Re: Who is using 10" Pneumatic Wheels

We had 6 harbor freight wheels mounted and running and had no problem with turning with a 1/4" drop. We had planned on articulating the center wheels to allow for a stable shooting platform, but when we built the whole thing it turned out to be a little heavy.

We are now running two of our pneumatic wheels in the center and 2011 kop wheels front and rear. Looks like it should be about the same performance, but it doesn't look as mean. Plus it weighs 40 lbs less, which is good if we want to attach anything that can do minor tasks like perhaps picking up an 8" foam ball and shooting it.

Re: Who is using 10" Pneumatic Wheels

we're using 10" pneumatics from harbor freight. They are our two front drive wheels and we have 2 casters on the back of the robot.

it turns pretty well, but that's all due to the casters.

If it was 4 pneumatics I can't say I know what would happen.

However, we had a team member sit on the robot and we noticed it drives much better under weight (the tires get more contact in the floor when pressed down).

I'd also suggest wearing them out a bit so the tread is flatter and, again, gets more contact with the floor.

Re: Who is using 10" Pneumatic Wheels

We're using 8" pneumatic wheels, one in the center of each side of our frame. We'll be mounting casters on the front and back eventually, but just driving with the two wheels and nothing else, it handles great! We're flying right over the bump and climbing the bridge with no difficulty.

How do you get up the bridge with casters on each end?

Sounds like they have some type of suspension system with a considerable amount of travel (well, compared to last year, it would have been fairly normal in 2010), or they've overlooked something.

Re: Who is using 10" Pneumatic Wheels

We are using 10" pneumatic wheels. Six wheel drive and it turns great, goes over the bump too. Here is a video.

Re: Who is using 10" Pneumatic Wheels

The wheels work really well on carpet and the bot spins like a top. We might need to power the front wheels, but we are getting over the bump with a moderate run up. It's like watching a monster truck.

Re: Who is using 10" Pneumatic Wheels

We have lowered the pressure on the front and rear wheels, which gives more of a cushion for hitting the bump, and gives higher traction for pushing on to the ramp at an angle.
