This 3 speed automatic transmission was built out of Legos. The transmission is driven mechanically, as there is no motor or external device required to change gears. It works using a spinning wheel that contracts and expands. The spinning wheel is connected to a gear shaft that moves between 3 states. At rest, a rubber band holds the spinning wheel fully contracted. As the car’s wheels speed up, the centripetal force required to keep the spinning wheel contracted exceeds the force of the rubber band, causing the spinning wheel to expand. So as the spinning wheel increases speed, it expands and the gears are shifted. (more…)

I designed and built this claw specifically for my high school’s remotely operated underwater vehicle (ROV). The claw is powered by a servo that has been multiplexed to open, close, and rotate the claw. The claw was built completely out of Legos. The servo somehow fit nicely in the Lego design (I don’t know how everything fits with Legos). (more…)

My school’s science club built this underwater robot for the MATE ROV (remotely operated vehicle) competition.  This was our first year in the MATE competition. (more…)

I designed this robot using the Lego Digital Designer (LDD) software. It consists of 1407 pieces, taking many hours to create.

The press of a button triggers a chain reaction built to launch a single dib across my room and into my mouth! (more…)
