This is an interesting height debate. What are other teams thinking ?

High wall cover prevents opponents from scoring over you.
Too high and your partners can't kick over you.

The DiscoBots are going with a similar wall robot with medium height.

What are you going to do to keep the soccer ball from going under your robot from the sides and rear?

Good Catch. We did not add the apparatus when the picture was taken.

Our solution is very simple, adds very little weight, allows us to go over the speed bump and easily removable. Any guesses?

I really like the use of COTS components. Very nice.

How does the both climbing and getting climbed on system work?

how do you keep balls from being trapped on top of the bot?

Here is the video of our robot lifting that I promised.

Estimated 300 pounds hanging on it after the lift.

First time I looked at it, I though the shelf with the little platic boxes on it was your electrical panel, but then I noticed it look unbelievably clean compared to any electrical work I've seen. Very nice looking robot. How comfortable is the driver with the mechanum drive (just asking, I have nothing against mechanum)?

Our driver absolutely loves the wheels and drivability. He was one of the reasons we went to these. This is his third year as our driver and he is incredible with what he can do given the right tools. We wanted to make sure that we gave him a very maneuverable bot for his senior year. He deserved it. As an example, last year during one of our competitions the robot lost all control of one side of our drive train. I lost my cool more than him (I'm the coach) and told him to do the best he could. Most would have quit. He could actually drive straight and make turns under these conditions. The team members in the stands new something was wrong but had no idea of the severity until we told them. I could go on and on with his abilities but just one more example. One of our mentors brought in a radio controlled helicopter. Long story short, with no exaggeration, he had it up and flying and doing circles all over the place in 3 minutes. He is truly amazing.
