Build: 2HCC Plus

This is the 2HCC plus (Two Headed Creepy Crawler plus). As the name state: it’s a crawler. Due to the moveable, outer tracks, this crawler can overcome many obstacles. With the moveable tracks it can lift itself up to a higher level. At a certain point it has to approach objects from the back, lifting te main body up first. This depends off the hight of the obstacle.

This crawler also comes with a set of claws. The big grip can lift cans and bottles. The ingenious design ensures that the claws open and close with the same motor that raises and lowers the entire arm. The key of this trick lies in a differential gear which can shift it's power from closing the claws to raising the arm.

The 2HCC plus has 4 motors and 4 sensors, of which two are optional. 2 main motors provide the drive for the tracks. The third motor provides the front tracks to rotate. The key to this is a turnable gear which provides rotation to the frame where the outer tracks are located in. The forth powers the claws.
