Cap Kart 2.0: 8/21/2010 Test Drive

Cap Kart 2.0: 8/21/2010 Test Drive

Added over 5 years ago | 00:02:44 | 12436 views

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. Af...

Auto-Gyro-Twitch

Added over 5 years ago | 00:00:48 | 9373 views

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 t...

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

Cap Kart 2.0: 8/7/2010 Test Drive, ...

Added over 5 years ago | 00:01:13 | 12453 views

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 additi...

Edgerton Center Engineering Design Class 2010: Project Highlights

Edgerton Center Engineering Design ...

Added over 5 years ago | 00:03:37 | 26757 views

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 ...

Cap Kart Summer '10 Rebuild - Rear ...

Added over 5 years ago | 00:00:28 | 14412 views

The improved Cap Kart now has lightweight lithium-ion batteries and a custom rear differential. This is mostly a test of the rebuilt rear axle, but also always good to make sure the controller still works, since it's cursed. Next orde...

Added over 5 years ago | 00:01:00 | 13907 views

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...

HexBridge Shield Demo

Added over 5 years ago | 00:01:02 | 10256 views

This is a high-power motor drive shield that I designed for the Arduino. I'm testing it on a large separately-excited DC motor from the Cap Kart. It has six semi-independent outputs, three of which are controlling the armature winding an...

Custom ESC: Field Weakening Test

Custom ESC: Field Weakening Test

Added over 5 years ago | 00:01:13 | 11193 views

This is a test of the brushless ESC I built for my 1/10-scale RC car. It uses sinusoidal AC commutation and field-oriented control, which dynamically adjusts the timing of the motor to optimize torque. As an extension of this control met...

Rookie (the dog) likes to chase squirrels. RC cars look like squirrels, I guess.

Pirate Radio Control: Custom RC for...

Added almost 6 years ago | 00:01:49 | 11800 views

This is the first test drive of my modified 1/10th scale RC car. It can reach a top speed of nearly 40mph with this gearing. It does 0-30mph in 2.2 seconds. More information. The car is a Team Associated TC4 RTR. Modification I made inc...

LEAF Motor: Spin-Up

LEAF Motor: Spin-Up

Added almost 6 years ago | 00:00:56 | 11182 views

This is the very first spin-up test of the Less Epic Axial Flux (LEAF) motor, to about 1500rpm. The LEAF motor is a "DIY" coreless axial-flux brushless motor. More information. The LEAF motor is the end result of a cheap set of wedge ma...
