Re: Effective Drive Base

Hey I have a question:

Do anyone have any idea to build swerve drive wheels?
Our team needs help designing the wheels and distributing the power from the motors.

I hope anyone can help and i cant wait till i see you all come to my hometown of the St.Louis regional!!!

I would recommend looking at the WildSwerve (look at the Andymark website) if you're interested in doing a swerve. However, if you aren't confident in the design principles behind a crab, I would not recommend undertaking it this late in the season.

Re: Effective Drive Base

There seems to be a lot of mis-communication and conjecture in this thread. I would suggest you simply build the kit bot using the wheels that came in the KOP and make a determination from that experiment/prototype. Each type of drive carries it's own set of pros and cons and risks for this game. Tank treads will climb but can cause excessive (near stall) current in turns if not implemented properly. Crab drive can be hard to control and requires a ton of practice to get it right. Drive systems that have a low COG on the floor may not have the same stability when crossing the bump. Prototype and then let the team decide which drive seems to work for the strategy and brainstorming you have (should have) done.

the WildSwere will not work going over bumps because there is a plate that is about 1" above the ground, and will get stuck on the bump before the wheel can make contact. My team is doing 6wd because of this problem (and our programmer doesnt want to have to figure out a swerve drive in 6 weeks)

I never said a Crab would be a good idea, nor that it would make it over the ramp. It would be possible to make a crab that can climb. Heck, it's FIRST! Teams have proven it's possible to make almost anything!

Edison,
I've seen you post this same question in at least four other threads. It is usually bad form to ask the same question multiple times, especially in different threads. I've seen your question was answered multiple times. Are you still having issues?
