CARS: Collapsible Autonomous Robotics Structures

Designed and built a modular block-based construction robot capable of scalable assembly. The project emphasized end-to-end development, from CAD modeling and FEA validation to fabrication, assembly, and testing. The robot was engineered to demonstrate structural integrity, manufacturability, and adaptability for real-world robotic applications.

The project began with the team identifying a real-world problem and developing a novel engineering solution. As a group, we explored several potential challenges before ultimately selecting the problem of modular space construction, focusing on how robotic systems could assemble structures efficiently in constrained or extraterrestrial environments. All team members contributed to shaping the overall concept and defining what the primary system architecture would look like. Once the core idea was established, the robot design was divided into four major subsystems, allowing parallel development. I focused specifically on the Z-direction locomotion mechanism, responsible for the robot’s climbing and vertical motion, and led the design and implementation of this critical subsystem while also helping with the other subsections.
