Build: Cran3 Master

CRAN3 MASTER is made using mostly parts from the Lego Mindstorms 31313 EV3 set, with some spare parts included. The build ended up covering the buttons on the EV3 intelligent brick, so I built my own buttons to press to ones on the brick. This robot can move forward, backward, and do zero-point turns. It can drive over rough terrain, and is very well balanced. It can also raise and lower a rope with a hook attached, and can lift up to four ounces, without putting to much strain on the rope and the belt that turns it. I built a pulley system that not only keeps tension on the rope, but also ensures that it does not bounce out of position. It is easy to take the batteries out: just take the beams off of the bottom and open up the intelligent brick. I hope you enjoy: CRAN3 MASTER!
