Chassis Front End Design

[J.Warsoff]

Camer up with this last night. It's hard to read, but the angle measurement at the bottom of the slope reads "30 - 45 degrees" and is just a rough estimation.

Comments?

We prototyped something similar with the kitbot with the plate made out of lexan, the plate sat a little higher than yours in relation to the wheel and had a 30 degree angle, it worked at very slow speeds successfully and calmly, only thing is you will need to do 8 wheel drive (to make it easy)

What about a nylon block / strip?

Did you have a wide or long chassis? We were testing it on a test wide chassis, and it was not pretty. The thing jumped straight up 3-4 inches off the ground. Once we get a test long chassis going, we will see what we need for wheels and drive. We had a similar system for our 2010 bot, without the lexan though. That was only 6 wheels, but did really will. We'll just have to see

Also, the drawing is not completely accurate. We actually have the entire wheel set a little farther back, so it is behind the lexan plate.

We tested a narrow base, this obviously helps, I'll try to get a video on Monday (our team doesn't meet Sundays)

EDIT: Also, our skid plate was curved rather than a straight angle, and was long enough so that it pulled the 6 inch wheel's center right at or little above the bump, thats the key
