Physics, Freshmen, Furniture... and a Grant Win!

There hasn't been a lot of action on this blog site so far this school year—but not because there aren't things worth writing home about! As you can imagine, I (Mr. Meadth) have been much busier on the ground each day with cleaning and supervision, let alone teaching the engineering class.

But some things are worth documenting and celebrating. So let's jump in!

1. Four New Freshmen

We took four new engineering students into the freshman class. A big welcome to Hunter, Abby, Teleios, and Eliana. These junior engineers are hitting the ground running, despite all the challenges. They are learning trigonometry before their time, taking baby steps into the world of computer-aided design (CAD), and just generally being awesome. Welcome, freshmen!

Hunter, Teleios, and Abby (Eliana couldn't make this
photo, but she's just as much a part of this group!)

2. College-Level Statics... From a Textbook

Despite my propensity to always design my own curriculum from the ground up, I tried something new this year: a textbook! It turns out this was the perfect year in which to do this, as it matched well to the statics studies that we've always done anyway. Don't be led astray by the name—Statics for Dummies—the lighthearted tone helps high schoolers get through those pesky equations. For those engineering parents out there, you'll find all of the fun you can handle in vector calculations, force couples, and free-body diagrams.



3. Independent Mode

This is a grand experiment, and one that we committed to from the start of the year. Can we commit to a full year of engineering studies in independent mode? Some would say that it's never been tried, but this is the year to come up with new solutions! Despite the absence of stimulating classroom discussions, this has allowed students to take seven classes plus engineering, and it allows students to watch at their own pace. Students have watched 18 videos so far this year, and responded with written assignments and discussion boards. They are now eagerly discussing their community design project in a shared Google Doc, which brings us to Number 4...

Acceleration sums in three dimension, anyone?
If you can't find the centroid of a composite area,
you just can't call yourself an engineer

4. Community Design Project

I'm so happy with how this project is rolling forward! We have two "clients", Mrs. Christa Jones on the San Roque campus and Mr. Gil Addison at PathPoint, who works with residents in wheelchairs. Our student teams are busily designing an adjustable standing desk for Mrs. Jones and an adjustable computer desk for Mr. Addison. Both of these designs are required to involve electrical/mechanical aspects, such as motorized lifts or built-in LED lighting. Once the student teams finalize their designs, complete with drawings and CAD models, I (Mr. Meadth) will be building their designs myself—in the interest of staying as contact-less as possible.



5. Lots of Publicity

We've received a surprising amount of national-level publicity lately. Our students use the CAD platform Onshape, and Onshape reached out to us to record a video and write a blog article. The video has been up for a over a month now, and the blog article will be published soon. Our Academy was also mentioned in another national publication by the American Institute of Aviation and Aeronautics (AIAA), Aerospace America, because we won a $500 grant to help build our remote-controlled aircraft.


6. Major Grant Win

Is it just me that believes in our outstanding Providence engineering program? Is it just the university lecturers who receive our already-highly-trained students? Am I just blowing my own horn over here? Apparently not! The Toshiba America Foundation decided that our second-semester robotics project was something worth funding, and we are pleased to announce that over $4,000 of the very latest in classroom robotics equipment will soon be arriving on campus. This will be put to use in our Mars Rover project, where different student teams will design, build, and code different components of one big vehicle. I'm looking forward to this one. Thanks, Toshiba!

One of the advanced Vex V5 sets: coming soon!

As always, stay posted for more exciting announcements. Our junior engineers are doing something very different, but making the most of it. I'm confident that their skills and experience will remain at the very highest level amongst similar programs in our area. Keep it up, students!

A Tour of JPL


(This is the eighth in a series of blog articles written by the Providence Engineering Academy students. Pedro in 11th grade reflects on his experience at the Jet Propulsion Lab in Pasadena on our class field trip earlier this year.)

“The trip was really inspiring way above expectations. I enjoyed the chance to see where they work, and the 2020 rover was a memory I will never forget.”

“It really re-awoke the third grade Nolan in me. The rover around Saturn replica was cool to see, it was a great experience, and I’m so glad I got the opportunity to go.”

These are the words Josh and Nolan stated about our class trip to the Jet Propulsion Laboratory (JPL). JPL was a fun and interesting experience, and in our tour we got to learn and see things that we’ve never seen before.

First off, we saw a video that was amazing to watch. This video showed us the gigantic size of the whole universe and taught us that most of it hasn’t been explored. It also showed some satellites and spacecraft that were launched into space, and we were able to look at smaller scaled models of these around the room.

Our host shows the various scale models of historical space probes

Next, we got to see the control room, which was full of screens and numbers. This is the room where they gather information from every spacecraft, rover, and satellite. It is also the place from which they controlled the landing of the Mars rover, Curiosity, in 2012—which we learned was a really terrifying seven minutes for these hard workers! 

The control center, from which every robotic space mission
has been monitored
Then, we got to see photos from one of the rovers on Mars. These photos had been taken just hours earlier and we got to see them on a screen!

After that, we got to see the construction of the 2020 Mars rover. Amazing! We learned that anyone that is eighteen or under can get their name applied on the 2020 rover.

Our final stop was the gift shop, which sold “space” ice cream, sweaters, and some cool toys for your kids. Overall, JPL was a fun and really cool experience for all of us.

Space: The Final Frontier

(This is the second in a series of blog articles written by the Providence Engineering Academy students. In the light of our recent trip to Jet Propulsion Laboratory in Pasadena, Ben in 12th Grade describes some of the history and future of space exploration.)

The concept of space travel has captured the public eye since the late 1800s with science fiction. As humans learned to blow things up in a certain direction more effectively, what was once science fiction became science speculation and from there we continued in our search for what lies beyond.

The entire group poses inside the famous JPL facility

On September 25, 2019, the Providence Engineering Academy was given the opportunity to take a glimpse into our country’s efforts to see just what else God has created in our universe at the Jet Propulsion Laboratory in Pasadena. We humans, as stewards of creation, have a special role in discovery and advancement of our world, and this stewardship is taken seriously at JPL. They have produced deep space telescopes, orbital telescopes, weather telescopes, rovers, etc. for this exact purpose.

Our host stands next to the life-size (non-functional!) sister of
the currently active Mars rover, Curiosity

Mankind continues our search for life on other worlds as JPL designs their next Mars rover, set for launch in 2020. This rover is designed to search the soil of Mars for any signs of life. As an engineering student, I am greatly inspired by the efforts that we as stewards make to find out more about our neighboring planets. Scientists are also hoping to research the seas of Europa, one of the largest moons of Jupiter, to see if there is any life below the outer icy shell. Since there are large bodies of water on Europa, many scientists wonder if creatures live there, just as there is sea life on earth.

this site, with a scale model of the Cassini probe in the background

Meanwhile, deep-space telescopes have been expanding the radius of what we know. There are upcoming missions for my generation to develop, based on all of the ground-breaking work done by the gifted scientists at JPL and other locations. One such mission is to develop a telescope to photograph other solar systems so that we can see if there are similar planets to Earth in those systems.

We deeply appreciated the enthusiasm and brilliance on display at JPL, and we wait with anticipation for what the future might hold—perhaps we'll be a part of it!

Summer Camp 2019

This summer, the Providence Engineering Academy once again hosted the very special Robot City summer camp. With assistance from four capable high school engineering students (Alena, Davis, Pedro, and Zach), Mr. Eves and Mr. Meadth put on an unforgettable experience!

(Please note that all photos in this article have been selected to avoid showing camper faces, since not all students are from Providence with a photo release. Apologies if you're looking for your loved one's smiling face!)

Day 1: Architecture
After breaking into four teams, each group selected the theme for their quadrant of Robot City. The Green Team chose Time Travel, the Blue Team settled on a Medieval Castle, the Yellow Team laid out an Alien Attack on the Beach, and Red Team was Future City. A quick lesson of folding geometric nets, and all campers from 3rd to 7th Grade were ready to build!

The skyline emerges! A colorful mess of card and tape!

Red Team's skyscraper went up and up and up, and needed to be
tied down with guy ropes!

Blue Team's "Nice No-Trap Castle". Should we believe them?

With inspiring challenges like "Tallest Tower" and "Most Colorful", each team worked hard to lay out their cities. Skyscrapers rose up six feet into the air, zip lines were strung out, and spaces carefully divided out.

Day 2: CAD and 3D Printing
It might sound complex, but physically printing CAD (computer-aided design) models is something within the reach of any elementary student! Mr. Meadth taught the campers how to use Tinkercad, a free in-browser design tool created by AutoDesk. Designers can use simple shapes such as cylinders, cones, spheres, and prisms to create more complex models, such as houses and rocketships and characters.

Two of our campers work on their CAD models (Owen's model
on the right is shown in detail below)

This is a great tool to get kids thinking in terms of linear dimensions, negative and positive space, perspective, volume, and it's just plain creative fun! Here are a couple of examples of what the kids came up with. We also had spaceships, tanks, flying cars, and castles. Wow!



Once created (the models above took the students less than an hour to build), the designs were sent to the 3D printer. At a small enough print size, most models were done in about an hour, in a range of colors. Of course, after the camp the students got to keep whatever they have printed!

It's just as addictive as watching TV, but at the end of the program
there's actually something to show for. Thanks, Raise3D!

Day 3: Electrification
Always a favorite! Mr. Meadth gave a quick lesson on simple circuits, explaining terms such as "LED", "voltage", "series", and "parallel". Each team was given a supply of copper tape, coin batteries, and LEDs, and shown how to connect them together to power their city. It wasn't long before the entire room was lit up with red, blue, orange, white, and green!

(the tidal wave was added later)

The Green Team's time travel zone included some helpful signs
(because time travel can be confusing)

All teams took up the extra challenges as well, building working paper switches, including both series and parallel circuits, and working to match their lighting arrangements to their theme. Blue Team created "laser traps" for their medieval castle, and Green Team strung out a long neatly-lit road to mark out their different time travel zones. Billboard were illuminated and "stained-glass" windows lit from the inside.

LEDs don't come through well in photos, but you get the idea!

When parents arrived for pickup on Wednesday, the lights went out, and the party started!

Day 4: LEGO Robotics
What's a Robot City without robots? This year, Mr. Meadth and Mr. Eves guided the campers on how to incorporate LEGO Mindstorms robotics sets. Rather than creating robotic systems that would move around (and potentially destroy delicate buildings and circuits!), the teams focused on stationary mechanical systems. Mr. Meadth gave some lessons on essential mechanical systems (bevelled gears, gear reductions, universal joints, cams and cranks, etc.), issued some fun challenges, and away they all went!

Does this look like anybody's bedroom floor? Times it by 16.

What's a medieval world without an authentic, functional windmill?

We were blown away by all of the amazing creations that campers and their team leaders built: several working elevators (with tracks and with pulleys/windlasses); a slowly rotating time travel portal (sadly not actually functional); a crank-powered shooting spaceship; an amusement park ride; drawbridges; a merry-go-round; several demolition machines!

(P.S. For any parents of elementary students wanting a more cost-friendly version of LEGO Mindstorms, I highly recommend LEGO Boost. At about $150, it is a somewhat simplified system, still with sensors, motors, and fully programmable using a block-based system. The only downside is that it does always need a tablet/phone/computer app to be running via Bluetooth to make it work.)

Day 5: Do Over
At this point in the camp, the kids have learned so many different things and have typically gravitated towards one or the other. Some of them think that LED illumination is the coolest thing, and others just can't get enough of making CAD models online. So on the fifth day, Mr. Meadth and Mr. Eves issued a few more challenges of various sorts. The teams helped put together a welcome sign with their photo on it; they all constructed a wearable accessory lit up with more lights and batteries. Some made hats and funky glasses and others made glowing swords!

The fun keeps coming on Day 5!

Robot City continued to grow in complexity and variety. Some teams incorporated sensors into their robotic systems, using touch triggers and infrared detectors to more accurately control their elevators and bridges.

By the time parents arrived at 12:30, the teams were ready for the final wrap-up. All points were tallied, and the all-girl Green Team took the grand prize, much to their delight!

Parents were delighted to see everything
the kids had accomplished... and that
someone else was handling the cleanup!

Mr. Meadth and Mr. Eves would like to thank all families for making our third Robot City camp such a success! We intend to run this again in 2020 (new ideas are already in the works!), so please spread the word amongst family and friends. You can start by sharing this article with someone who might be interested! And remember, this camp is open to all students, not just those from Providence. We're always glad to welcome new friends from outside our regular community.

Until next year, may these junior engineers keep on designing and keep on building!

Searching for Solutions: Search and Rescue Robot Challenge

(Our latest blog article comes courtesy of Joshua in the 10th Grade.  Thanks, Josh!)

In the event of an emergency, robots may be called upon to enter into areas which have been devastated by natural disaster. The thirteen students from the Foundations of Engineering II class split up into four groups to build such robots, and testing came after eight weeks of work and dedication!

The original CAD model of the obstacle course, constructed
over several weeks by our indefatigable teaching assistants,
seniors Josh and Claire

The testing included nine phases (any of which could be skipped) all while carrying a payload. The teams would go through two gates of different sizes, over a gravel pit, up onto platforms of varying heights of 50 and 100 mm, push a block with the mass of one kilogram, go across a chasm, and make their way up a 45° incline. At the end of the run, the robot would be required to drop off the payload. The driver for each team would first do this routine while watching from nearby, and then once again using only a first-person camera view.

no worries at all

The first robot to test was the "Trapezoidal Tank”. This robot was built by Nolan, Davis, and Alan. They felt ready for the first trial of the course, but decided to skip the 45° incline. Everything ran smoothly until the payload drop at the very end. They realized something was wrong.

The payload mechanism’s motor came unplugged!

Davis, the driver, thought up an idea. The payload was resting on top of the robot. What if he just flipped the whole robot over? Using the tank’s "tail", he flipped the robot up onto its end and delivered the payload.

Although not able to climb the full 45 degree slope, with a slight
modification the Trapezoidal Tank was make it at 40 degrees

A moment of pure glory! Davis upends the entire robot and performs
the obligatory victory dance!

On the camera-only run, the course was successfully completed again with only one obstacle skipped.

clambers over the gravel pit obstacle

no easy feat! 

Pushing the one-kilogram block away, the package waiting to be
delivered is clearly seen on the right-hand side of the robot

This complex (and squeaky) maneuver involves a series of
high-torque gymnastic activities


Next up was “Daddy Long Legs,” a robot with motorized wheels attached to extended legs. It was built by Caleb, Sydney, and Zach. Caleb, the driver, slowly completed the run, also skipping the very difficult 45° incline. On the camera-only trial, the robot was not able to place the payload in the designated area.

Anaconda brings its bulk to bear on a one-kilogram block of wood

This monster robot leaps 100 mm platforms with
a single bound!


Next was “Anaconda”, built by Sam P., Isaiah, and Pedro. It’s most notable feature? The robot’s tracks could rotate all the way around to point in the opposite direction. Sam P. took the wheel, and on his first run, he only skipped the smaller gate. On the camera-only run, he made it through the same obstacles without any issues.

James steers the Iron Horse through both gates and up onto
the 100 mm platform

Finally, the "Iron Horse” entered. This robot was built by Sam K., James, Joshua, and Kaitlyn. The design was simple yet effective. However, the extra mechanism they had added to their robot at the last minute broke! It was designed to help them get up onto the two platforms. Fortunately, there was enough power available for it to slowly assist with the obstacle it was built for.

Charging over the gravel pit with a huge ground clearance

Shortly after, that extra mechanism fell off and so did the payload. In a lengthy and complicated series of maneuvers, James used the one-kilogram block to push the payload over into the designated area.

End of the road: the Iron Horse capsizes while trying to free its
jammed package (the small yellow catch was supposed to release
and allow the hinged door to fall)

On the camera-only run, the Iron Horse's payload wouldn’t release. James used the gravel pit to try to get the payload to come loose, but the robot flipped over. He attempted to flip the robot back over, but it tipped over on its side instead. This run was incomplete.

The lesson to be learned for these four groups? Each problem can be solved in many different ways, but some are more effective than others. In every problem you encounter, consider those many solutions and then choose the most effective one.

Search and Rescue Robot Photos: Josh Guinto

One of the strengths of our Engineering Academy is the opportunity to assign older students to act as teaching assistants for the younger group. This year, we are privileged to have Josh and Claire, both seniors, working behind the scenes day in and day out. Josh and Claire take care of so many important things, freeing me up (Mr. Meadth) to focus on teaching and assisting students.

Following on from the highly successful robotic arm project, our current robotics challenge is to design and build a search and rescue robot. This idea has been widely explored by many universities and private companies. We are proud to have four separate teams, each developing a unique solution for a robot that can navigate a defined obstacle course and deliver a survival package to a person on the other end. Such a robot might be used in an earthquake scenario.

No more talk from me! Let me simply share some excellent photos taken by Josh (thanks once again!) We'll send out an update once this project is completed, so stay posted.
