See you in L.A.!

Even though we had the mass available for a turreted arm, we opted out. We were concerned about robot stability and the extra complexity for marginal benefit. Closing distance on the ball when it's not in front of the robot would require some sort of swerve/omni/crab drive, which we don't have.

Enjoying winter?

Is the circular "palm" of the gripper a touch sensor? Or is it an elaborate device for something more specific?

No, it's just a fiberglass "dish" that a student wanted to make to cradle the ball. We might mount an ultrasonic range finder in it, since high-power radar is not an option...

Do it! I like robots with character. I'm pretty sure I'm not the only one. Again, can't wait to see it.

Yep...Though the Minnesota folks around here think it's not cold enough! (We had blowing snow all morning and early afternoon, and it's currently +20 F...)

Haha, it's +3 F here at the University of Minnesota, but I would trade it for +20 in a heartbeat!

On topic, it looks like you guys built a solid robot that should be able to consistently perform.

The last two nights it's been in the negative double digits and my house. Tuesday night was -16F and last night was -12F. I love winter! I just wish we had more snow for the snowmobiles.
