Iowa State University - Robotic Mining Competition
2017

 
This was a club I was in back in 2016 and 2017 at Iowa State.  These are a twin pair of mining robots entered in the NASA robotic mining competition.  I was responsible for all the PCB design, wiring harnesses, and software for the power management system. 
 
  • Zynq 7020 based system
    • White box on left side of the rear of the robot
    • Controls all motor drivers
    • Receives all sensor inputs
    • Communicates with base station for remote control
  • Power management system: Smart Management Of Robot Energy (S.M.O.R.E.)
    • Monitors and controls power for all motors, sensors, and the main controller
    • Manages startup, shutdown, and emergency stop
    • Prevents damage from inrush current
    • Supercapacitor backup to allow graceful shutdown when power is cut
    • Black, brown and white box (sort of resembles a s’more) on the right side of the robot
