4pcb is a miniature quadrotor built on a single printed circuit board. (The board is its structure and its electronics.) It weighs 125 grams and is powered by four brushless motors. The processor is an Arduino Mini. It's radio controlled and has a 6-degree-of-freedom inertial sensor for stabilization. The control loop still needs some tuning, and yes it could also use some landing gear. More info: http://scolton.blogspot.com/search/label/4pcb

tinyKart is our ultralight electric go-kart. It currently weighs 55lbs with a final target of 53lbs. The top speed is 30mph (controller limited). The custom chassis is made from aluminum plate and extrusion. It's propelled by two 2kW RC airplane motors and two electric bike controllers. The battery is a 37V/9Ah lithium polymer pack weighing 6lbs. The range is unknown.

This is the first test drive of Pneu Scooter, an electric kick scooter with 6" pneumatic wheels and a custom rear hub motor. It's version 1.-1 because, for this test run, it's running on an off-the-shelf brushless DC electric bike controller. In the future, it will have custom synchronous AC control.

[LESS INFO] 11 VIEWS | ADDED 12:43:30 11/01/10
Here are two of the first test-spins of the custom pneumatic wheel-motor for my latest scooter project. The motor is a three-phase brushless outrunner, designed for about 1600rpm at 33V and a peak torque of about 5ft-lbf. The controller is also custom, a 48V/1kW field-oriented synchronous AC drive that still has some software? glitches to work out. More info: http://scolton.blogspot.com/search/label/scooter.

Cap Kart 2.0: 8/21/2010 Test Drive

[LESS INFO] 1 VIEWS | ADDED 16:08:56 08/23/10
This is our second test drive of the new Cap Kart. The first run ended similarly to the first test drive: with a dead MOSFET in the controller. This time we came prepared with a field soldering kit and a less volatile replacement FET. After that, things went smoothly and we got a good chance to test the various improvements we implemented this summer. These include: - Thundersky 40Ah lithium iron phosphate batteries to replace the old lead acid batteries for a weight reduction of about 100lbs. - A custom rear axle differential based on design from LOLrioKart (of internet fame). - New field control modes for the separately-excited DC motor, including "three speed manual", reverse, and continuous field weakening. - Better data visualization and logging, plus fault detection.

This video demonstrates some upgrades to Twitch, Jr., my linkage-drive robot. It was pretty difficult to drive, so to help I added a yaw rate sensor (gyroscope) and a heading control loop. I also added a mode that automatically selects the wheel positions based on a single joystick input. For more information, click here .

Cap Kart 2.0: 8/7/2010 Test Drive, Conquering the Turn

[LESS INFO] 4 VIEWS | ADDED 02:37:57 08/10/10
Okay, so it's not the fastest or most impressive test drive we've ever had. (The kart suffered a[nother] MOSFET failure after a few runs.) But it highlights one of the new features: a custom-built rear axle differential. With this addition, and savings of about 100lbs by switching to lithium-ion batteries, it easily navigates the slalom course. Back in 2008, clearing the u-turn was nearly impossible even at low speeds. Don't ask why Elmo is used as a slalom cone. For more info about the Cap Kart, see http://web.mit.edu/first/kart.

This summer's Edgerton Center Engineering Design class produced four awesome projects in four weeks: - A functional RC quadrotor built with commonly-available RC equipment and an Arduino microcontroller board. - A 4x3x(8x8) LED matrix screen capable, among other things, of playing accelerometer-based pong. - An illuminated polycarbonate-based makeover of the DIY self-balancing scooter featured in 2007, also with functional steering. - A lighter, faster, and more maneuverable Exkate-based electric longboard.

Imprecise Aggressive Maneuvers for Remote Control Quadrobots (a.k.a. Twitch, Jr.)

This is the very first test drive of Twitch, Jr. It's named after its larger predecessor, Twitch, built by FIRST Team #1565 in 2008 ( video ). I'm not associated with 1565...I just decided I had to make a small Twitch. The "linkage drive" and omni-wheels allow it to take several different robot drive configurations, including standard, wide, and diamond layouts. With practice, it should be able to move seamlessly from one configuration to another. With practice... For more information, click here .

DIY Segway @ Wayland HS
08/30/07

The DIY Segway makes a trip out to Wayland HS, and gets truly put to the test by some of the designers/builders. They know how to push it to (and sometimes past) its limits... More info: http://web.mit.edu/first/segway A group of about 12 students (MIT undergrad and grad plus high school students from FIRST Robotics teams 97 , 2043, and soon-to-be-numbered Wayland HS rookies , and The Education Cooperative , have taken on the summer task of constructing a functional Segway-like scooter. Sponsored by The Edgerton Center , the D.I.Y. Segway is both a fun summer project and an educational experiment for hands-on engineering curricula.
