GorrillaBot

Our initial goal was to build a custom bipedal robot capable of independently walking on two legs and transform into a quadrupedal stance using a servo-actuated hinge - as seen in the first image. As we got closer to the final deadline and realised our final grading was exlusively based on the speed of the robot - we pivoted!

We instead connected two of our existing bases together using scrap alumnium and zipties and build a quadrapedal robot that was fast enough to get us the highest grade! All in the last 2 days!

There were many important takeaways from this project, from the extensive (bordering on absurd) iterations the could have been minimised by more intentional thought to learning how to adapt engineering projects on the fly. Some of the hard skills learnt range from Robot CADs, Algerbraic topology for pieces, Sim2Real Python simulations, Developing gait patterns, etc.

High-Speed Arcade Button Pressing Mechanism

Designed a single-motor linkage to rapidly reposition and press multiple arcade buttons, optimized for low inertia and repeatability.

Owned mechanism + control optimization (encoder feedback, homing/limits, hard stops) to maximize speed and reliability.

Iterated through prototypes and timed trials, learning what actually matters when tuning real machinery.

Robotic Bartending Arm — Kinematics + Workspace

Modeled a multi-DOF arm with DH parameters and derived forward/inverse kinematics.

Analyzed workspace + singularities and validated trajectories in simulation.
