NASA Human Exploration Rover Challenge

Executive Summary

The purpose of the NASA RC Rover project is to design a robotic vehicle capable of completing all challenges listed in NASA’s guidebook. These challenges include navigating rough terrain and performing precision tasks, such as drilling and vacuuming samples, with no contamination. This design attempts to meet all of NASA’s challenges and successfully perform through testing. Since this is the first time a team from Texas Tech is participating in this challenge, this design will become a framework for other teams to build off in the future. :contentReference[oaicite:0]{index=0}

Notable components of our design include a rocker-bogie suspension system—modeled after Curiosity & Perseverance—for stability over rough terrain; a lightweight aluminum frame; and 3D-printed components to reduce cost without sacrificing strength. Testing led us to switch to 14 gage wiring for the drive motors and upgrade the vacuum’s power source. We also recommend ≥ 1″ bearings in the arm joints for full operational reliability. Overall, the suspension and controls meet NASA standards, and this rover is a solid first step for future Texas Tech teams. :contentReference[oaicite:1]{index=1}
