Re: Minibot times

We're just under 3 seconds but time up is only part of the challenge. The other is deployment just after the 10 seconds which is also a challenge. We've added a guide to help hit the pole with a larger margin of error but still figure it will take another second or two to deploy it on the pole. That doesn't leave teams over 4 seconds much time to make it.

Re: Minibot times

Sadly we've been getting upwards of 6 seconds.

From what I know we've yet to solve the main problems of slippage and falling. (Minibot randomly falls from the pole due to it starting to drive away from the pole)

Re: Minibot times

Magnets...Neodymium are the way to go. Holds on real well.

Re: Minibot times

We are getting 3.5-4 seconds but may play with new wheels/magnets between now and GSR.

Re: Minibot times

Team 1827 is getting about a 3.5 second climb. Deployment time varies with a strategy choice. No magnets or custom wheels on ours.

Re: Minibot times

Consistently 4 seconds... Now my team is all "bloated in the head" after a scrimmage with majority of the teams did not successfully deploy a minibot once. We deployed correctly only about 50% of the time because the robot could not turn. Now my team captain does not want to optimize the minibot. Honestly I feel a slap of reality coming at the regionals.

Re: Minibot times

Minibots are cheap, David, relatively speaking. Do what a team member and I are doing between now and Duluth: build another minibot. Our current one can do 4.5 with half second deployment every time, no sweat; however, this can be done better, so we'll try with extra parts we have lying around.

I'l try to find you and show you at FLR, but it means that they have taken off the gearboxes on the tetrix motors, and are "gearing" them by using small wheels, usually custom manufactured.

We've tried that, and thus far are failing rather dramatically...
