Are robots with omni wheels capable of going up robots with ramps? i mean is there enough traction?
I’m pretty sure this is an impossible question to answer considering the different applications of omnis (tank steered and holonomic) as well as the different materials/angles teams might design their ramps with.
We did last year! It was pretty easy! As long as the traction wheels go up last
Do you mean using omni-wheels in a traditional scrub (tank) steering drive, or a full fledged omni-directional drive-train (holonomic, mecanum, etc.)?
Its also hard to tell becuase from what our team has calculated the ramps are gonna be pretty steep this year
last year I saw some teams with holos climbing up on ramps . . they got a good running start but they did it.
also I think the ramps this year are going to be easier than last . . least all the ramps Ive seen are;)
People saw how hard it was for some people to get up the 30 degree ramp last year so i’d venture to say the ramps won’t be that steep. we had omni wheels in the front last year and we got up the ramp pretty well. like said before…as long as you have the traction in the back, you’ll make it if you have enough power with it.
I think tank style might be able to go up a 20 or 25 degree ramp, but any other steering style won’t go up a ramp.
With enough traction and how small these ramps will be, it shouldn’t be a problem. Plus, if you code a gyro to make you drive straight, you don’t have to worry about swerving to the side.
I doubt a omni-wheel holonomic can, but I think both a omniwheel+treaded wheel and a mecanum wheel robot can go up a graudal ramp.
Our off-season practice mecanum drive base drove up last year’s ramp without difficulty – if it was perfectly lined up. Any significant error in approach angle made it lose traction on one corner or another, making it spin or slide unexpectedly away.
The main difference between last year’s 30 degree ramp and a 30 degree ramp (or steeper) this year will be the material the team chooses to make the ramp out of. A team could add grooves and use a material that provides more traction than diamond plate… I don’t expect ramps to be much of a problem for many drive systems this year… as long as the ramp isn’t made out of something like teflon.
Last year we used two pnuematic wheels and two undriven omni wheels. We made it up the ramp with a running start and the omni wheels in the back. If we tried putting the omni’s in front, they usually slid sideways.
