COMPETITION

The objective of the competition is to build and design a small robot to navigate a 16x16 maze, traveling from a random corner of the maze to the center in the shortest time. The competition is open to any undergraduate group, and 2017 is the sixth year that we have participated at the Brown University IEEE Robotics Olympiad.

MICROMOUSE 2016

Our team claimed First Place in the 2016 Brown IEEE Micromouse Competition. Our robot managed to solve the maze in less than half the time it took the second place robot to do so!

MICROMOUSE 2017

In 2017, our team placed 2nd at the Brown IEEE Micromouse Competition and also won the Best Design award! 

 

We are currently developing a new and improved Micromouse to compete in 2018!

2016 Design Specifications

  • 3 IR distance sensors and 2 Hall Effect motor encoders to determine the robots position and orientation as well as for detecting walls.
  • Powered by 2 DC motors, controlled throuh a H-bridge motor controller via a pulse-width modulated signal
  • Controlled by an Arduino Micro
  • Integrates the information from all onboard sensors into a flood-fill maze navigation algorithm.

2017 Design Specifications

  • 5 ToF sensors at the front of the chassis, giving 180 degree input range. 
  • Custom PCB design - smaller, faster, minimal wires for sleeker design.
  • One magnetic Hall effect quadrature encoder on each motor.
  • Quadrature encoder library keeps track of motor shaft position.
  • PID control:
    • run on shaft position for dead reckoning.
    • run on ToF sensor reading for wall-following and front-aligning.
  • Teensy 3.2 microcontroller
  • Integrates the information from all onboard sensors into a flood-fill maze navigation algorithm.
