good job, thats impressive for tank tracks. did you try it on carpet?

#3

we dont have carpet at our school :frowning:

#4

get a large rug or something and ductape it down, thats what we haveā€¦

#5

yea reminds me of a robot 401 made years agoā€¦though we were using drill motors.

as for the carpet we are lucky to have a rather large area in our shop that is carpeted.

#6

Yes I would find some carpet. . . . if needed take it to a local business that has short commercial grade carpeting in their lobby. The robot may not turn how you would like it to. Just a word of warning.

#7

well it looks like its ment for speed,ā€¦ it needs bumpers and i pry for your sake that it dosent get crushed, but over all i love the performace givein from it
:smiley:
have fun building!

I feel like it is necessary to reiterate this statement. The friction of carpet is very different than what you are seeing in your tile hallway. Your robot WILL perform differently on carpet.

Every year I see this at least twiceā€¦a robot that is flawless in a hallway or a gym, but when it gets on the field it canā€™t overcome the friction and is only good at going in a straight line or worse it canā€™t move at all.

Please Please Please find some carpet and try it out, at full final weight.

I am going to third Gregā€™s request. Please get carpet and try it out on that. You will be suprised at the differences.

After 4 years of coming home from the pre-ship scrimmage and having to rework our drivetrain, Iā€™m going to jump on the ā€œfind some carpet to test it onā€ bandwagon. The scrimmage was always the first time we drove the robot on field carpeting. The year we did tank treads we had to significantly rework the drivetrain in the two days before shipping, and still had problems on the carpeting.

After that, we got a piece of actual field carpeting to roll out in the hallway for testing.

#11

no offense but ower robot is faster than that in first gear.:slight_smile:

#12

speed isnt everything budā€¦

and since im posting, i might as well jump on the bandwagon and beat this to death as well, carpet, carpet, carpet you will notice a considerable difference in your maneuverability and speedā€¦

If you havenā€™t figured out that testing on carpet is important, just one more post to that effect might convince you. It will be very different!
