2016, BunnyBot Unveil and recap videos from 2471

[AlexanderLuke]

For those who read this and are in the same boat as me, here is a thread that 2471 also started with the drivetrain that is running on one of these robots. Also, Here are the rules for the competition.

These two robots look awesome! I'm not all that familiar with the BunnyBots competition, but please bear with me as I ask these questions (as perhaps their answers revolve around the rules of the competition)...

Before I start, ThunderMcBoomStix is one of the most unique and strangely hilarious names I've ever heard of for a robot.

1. Bumpers: What is the bumper fabric on Speedy, and how is that material holding up(looks unconventional from what I am used to seeing)? What was the reason behind trying it out(supposed to lower CoF, more durable, etc)?
2. Bumpers: Is that ballistic nylon on ThunderMcBoomStix?
3. Drivetrains: I saw the car drive on Speedy here, but what is powering ThunderMcBoomStix? Are there some omni wheels on it? The turning seems wonderful.
4. CAD: Please tell me there are CAD models that I can take apart to learn from these robots.
