Overview
#

TachyAstroach: MoonLine is a mother-daughter rover system where the primary unit launches a secondary sub-unit, with both coordinated wirelessly through custom actuation mechanisms. The project was completed during a 36-hour intensive build at the GT IEEE Robotech Hackathon, transforming raw materials into a functioning extraterrestrial rover prototype.

My Role
#

I led the mechanical design of the rover system using Fusion 360, collaborating closely with teammates on electronics, control algorithms, and communication systems. Throughout the hackathon, we CAD’d, cut, soldered, coded, and debugged through the night to bring the rover to life.

Technical Details
#

  • Design Tool: Fusion 360 for full mechanical design
  • Materials: Tough 2000 resin, ISO bolts
  • Systems: Attitude control systems, bus communication protocols
  • Integration: Mechanical engineering, electronics, and software working in concert to enable wireless coordination between the mother and daughter units
