Here is a short video of our 2007 robot fitted with the 2009 wheels on the FRP with a trailer. The child interacting with the moving machine (retrieving orbit balls) is my son. So, bad parent alert, but he has been dodging robots all his life.:o
This is great. We did some testing today with our skid steer kit bot with mixed results. Would you mind commenting on how your drivetrain works? I can definitely see those front wheels rotating.
This 2007 robot has a three-wheel (what we call) “articulated” crab drive system. All wheels are driven with CIM motors and steered independently. The regular steering configuration is such that the wheels drive around the center of the robot, i.e., when it turns right, the front wheels go right and the back wheel turns left. Then crab is all in the same direction, of course. The crab drive is pretty handy for getting out of the corners with the trailer. This robot is not driving very well, because we just threw the wheels on and the software needs tweaking, but those guys are busy with the new design!
(I hope my answer isn’t too lame, I am the HoF/business group mentor. The technical guy around the house is soundly asleep in his chair - we just got home from the shop.)
Sorry to here about your robot … we have had some problems this school year to … But back to the fact …
excellent idea on the new wheels with the older robot … i have one question …
whats the steering like …and do you have any pointers on building it robustly …
we have our drivetrain built the same way with two all four but are having problems on mounting positions … because of are UNIQUE shape of our robot this year …
if you could get back with me that would benefit … im currently re-designing it to make it work but im struggling … sad to say:confused:
Are you asking what the steering is like on this floor?
