Team 3512 Sneak Peek
 

Footage from the initial day of testing our 2015 bot, Talos:

I wish I had captured more video of it! Maybe tomorrow.

Looks speedy! If you guys have a second robot, some good programming could turn it into a real demon.

Re: Team 3512 Sneak Peek
 

Thanks!

Only built the one bot unfortunately! But we have another week of software to test with lots of encoders and limit switches to implement so hopefully it'll be much faster and smoother by stop build day.

Very fast elevator! I noticed the motor back-drives. Does your team have a solution for it?

Re: Team 3512 Sneak Peek
 

What motors/gearbox are you using to drive the lift?

Re: Team 3512 Sneak Peek
 

Mechanically no, but we are planning to do this in software.
Also, it doesn't drop that dramatically under normal conditions, but in the video, the programming team disabled the robot a second after it starts lifting which is why it drops suddenly.

We are running an AndyMark Super Shifter 30.1:1 (not utilizing the high gear) with 2 CIM motors. On the output shaft of the gear box is a 48 tooth sprocket which is connected by #35 chain to a 26 tooth sprocket at the top of lift.
