I am sure its built like a tank, like all your robots in the past! 
Actually built more for speed:) only weighs about 106 right now. We had fun playing with your 2512 people at Grand Rapids this weekend.
I was a big fan of the hinged hopper so you could easily get to the wires.
A little history about the robots name, BB-876, Last summer we lost our mentor and part time drive coach Ben Bartle to a fatal work accident. When it came time to name the robot bunch of people independently came up with BB-876, a combo of Ben Bartle And the Star Wars droid BB-8.
Great looking robot
