This is the the yearly pre-competition video for Ithaca NY based FIRST robotics team, 639: Code Red Robotics.
This years robot, named "Duck 'n Cover" because of it's distinctive bill was built to be a defensive robot, but is extremely versatile. Due to it's treads with two-speed transmissions, it is fast enough to act as a feeder, but if it encounters other robots on the field, it can plough through them.
The elevator can pick all tubes up from the floor, and lift them to the second level reliably, or take tubes from the feeder slot easily.
