The trip to Parallax referenced in the previous post was a fruitful one indeed, as we (Folsom Lake College) ended up being the recipient of a sweet, brand new Propellor QuadRover.
The bot is a burly little beast, a sturdy metal frame housing a 4-stroke Honda gasoline engine, a hydraulic propulsion system, disc brakes, and a powerful Propeller microcontroller.
Spent Saturday trying to find ~4 cups of ISO-46 hydraulic fluid, and finally ended up buying 2.5 gallons, which means I ended up with all the robot will need for the foreseeable future. In any event, the hydraulic system and the motor check out, and after charging the battery, I tried in vain to get the RC controller to communicate with the bot. I’m pretty sure the receiver is shot, so I’m looking into either securing a new one, or undertaking the delicate soldering that will make it work.
What will we do with the QuadRover? That remains to be seen. I’ve lately been thinking of both the rover and the soon-to-arrive quadcopters as sensor platforms. That is, the plan is to equip them with an array of sensors and data loggers, and figure out amazing instructional activities that make use of the data. Ideally, I’ll get the whole system working, and then challenge students to come up with the use cases. Any bright ideas?
Spent the morning at Parallax, meeting with various folks and talking about partnership opportunities and that sort of thing. Nick (he’s working on the ELEV=8 platform, and he’s helped me a great deal, answering technical questions and providing guidance) flew a Y-shaped ELEV-8 prototype for us.
Chance favors the connected mind.
So I had this idea. Perhaps it’s more appropriate to say “we” had this idea. More about that below. About 40 seconds into this video, it hit me: use quadcopters to gather high resolution images that can be used by students in the Geosciences.
Meanwhile, Gary Hartley (Dean, Instruction and Technology), has been wrapping up a multi-year grant called CPATH. In a nutshell…
CPATH is concerned with Computational Thinking – a way of describing problems and devising solutions that can effectively utilize the power of computers and computing
Additional information about CPATH can be found here. I’ve been in conversations lately with Gary about the successor grant, and multi-year, multi-dollar affair NSF grant called Computing Education for the 21st Century, or CE21. You can read about it here. The content of those conversations, which also involved Stu Van Horn (Dean, Instruction and Careers and Technical Education) had to do with re-imagining CIS at Folsom Lake College. Over there is a little cocktail napkin drawing that I devised to frame the conversation. I’d love to see the college move toward a DIY, hardware hacking ethos, with iRobot Roombas tooling around the college building 3D maps using Microsoft Kinect sensors, and all kinds of fabrication and Makerbots and lasers and Arduinos and that sort of thing. An interdisciplinary, maker/hacker/tinkerer sort of program. Applied computing and engineering and art and GIS and music and biology and everything else. Blinking lights and whirring sounds and the sharp smell of ozone – that’s what learning should be like. Perhaps one day the college will get there.
In any case, a month or so ago, a student named Dave approached me about starting a robotics club at FLC. He’s working on the charter as of this writing, and I will serve as one of the faculty advisors. About that same time, I became aware of a local organization called Dweeb Den, a collection of folks attempting to establish a hackerspace in Sacramento.
On Saturday, February 18th, 2012, I attended the Dweeb Den kickoff meeting. The meeting took place in a conference room at Parallax, a local company that makes microcontrollers and robotics kits. The meeting concluded with a demonstration of Parallax’s ELEV-8 quadcopter platform. Equipped with a GoPro camera, the quadcopter flew around the parking lot, then soared high into the air. A week later, the Dweeb Den folks posted the video of the quadcopters flight, and at ~40 seconds into the video, it all hit me like a bolt of lightning.
As if consumed by fever, I quickly drafted a proposal and budget, and working with Jason and Gary and Stu, we were able to find funding for a prototype. The project will help FLC students develop technical geospatial analysis skills and learn contemporary applications of geospatial imaging, and the images will be used for spatial analysis; evaluating landscape changes, hazard analyses, and investigating rural and urban development.
Requisitions are moving through the system now. I want to document as much as I can about the project, about successes and failures, hurdles and challenges and red tape and process. It is my hope that, should the project prove successful, others might find the information here that they need to engage in similar projects, or better yet, that they might extend and adapt the idea.

TL;DR We’re going to put cameras on quadcopters and take pictures for students studying Geosciences to use.
