Autonomous
robot

Five tasks. Forty seconds.

Built for a 40-second autonomous competition, this robot combined a launcher, passive carousel, and folding delivery arms on one compact chassis. I created the full SolidWorks assembly and developed the launcher, then fabricated and tested the robot with three teammates.

Final design

Inside the robot

One motor drives the chassis. A single pneumatic cylinder releases the launcher and swings the delivery arms. MDF decks, aluminum axles and arms, and custom 3D-printed parts keep the assembly within the size and budget limits.

Pneumatic-release launcher

Rubber bands store the launch energy, and the pneumatic cylinder pulls a retaining pin to release the arm. An adjustable stop controls its travel. The launcher reached the second scoring tier in competition.
