Team 1629 GaCo's Test Bot On Field
 

These are videos of our test bot on a full sized field. The videos are taken from different angles.

The Robot actually turns better than I expected.

Wow, looks like you are getting great traction and great handling.

Have you really geared everything to limit your drive torque?

Re: Team 1629 GaCo's Test Bot On Field
 

Great video, that answers a lot of questions we had. Thanks for posting!

Re: Team 1629 GaCo's Test Bot On Field
 

I think our programmer just limited the power output to the motors. As far as I know we have the standard kit Andy Mark Tough Boxes on that test bot.

Re: Team 1629 GaCo's Test Bot On Field
 

That's really good! Does this mean your team won't be going with the brilliant 4 wheel steering system you had last year?

Re: Team 1629 GaCo's Test Bot On Field
 

We really arent sure yet.... I guess everyone (including me) will have to wait and see.

Re: Team 1629 GaCo's Test Bot On Field
 

is this on the regolith field?

Re: Team 1629 GaCo's Test Bot On Field
 

wow.. are you guys planning on having any kind of ball capture?

Re: Team 1629 GaCo's Test Bot On Field
 

Nice driving! We won't know until competition but I don't envision most teams moving faster than that around the field this year or they'll quickly find themselves crashing into the boards like a bad hockey player.

Re: Team 1629 GaCo's Test Bot On Field
 

This was on the "regolith" field. While we do plan on some sort of system to handle the balls, but we have not yet made a final design decisions on this system or the drive system.

Re: Team 1629 GaCo's Test Bot On Field
 

Notice they have the wide chassis setup as well. Easier to turn and maneuver as a lot of people have stated. It seems like you guys have more control than I thought the regolith would allow, so that's good. Thanks for posting the video.

Re: Team 1629 GaCo's Test Bot On Field
 

how much did the field cost?(just the regolith)

Re: Team 1629 GaCo's Test Bot On Field
 

I heard something like $1200.... We are just helping to keep Home Depot from going Bankrupt :D .

Re: Team 1629 GaCo's Test Bot On Field
 

Nice! How are you limiting your power? Is it a simple never exceed X% of power, or is there some sort of feedback loop?

Re: Team 1629 GaCo's Test Bot On Field
 

wow:yikes: you should let teams come use your field

Re: Team 1629 GaCo's Test Bot On Field
 

This is a prototype to test out the field conditions...This is NOT their complete robot.

A couple questions:

Does this thing weigh the full 120+bumpers/battery?
Did you have any feedback to determine when you are slipping or did you just limit your acceleration?
Is it as easy to control as it looks?
Any problems you've run into?

Re: Team 1629 GaCo's Test Bot On Field
 

That appears to be the general consensus. Most people apparently overestimated the lack of friction, including us. I still agree that most people probably won't be going too much faster than that.

Re: Team 1629 GaCo's Test Bot On Field
 

The Bot did not weigh anywhere close to 120 pounds. My best guess would be not more than 60 lbs. We only limited the acceleration by hand (slowly moving the joystick). It was also fairly easy to control, once you get used to the fact that you can't let the wheels spin and that you have to go easy on the joystick. One problem was that you cant just let go of the joystick to stop. If you do this you will slide. You have to slowly decrease the power just like you were accelerating from a stop. A steady and gentle hand is definitely a good thing. Also let the trailer help you turn. This comes naturally after a 30 minutes or so or practice.
