Refreshment Replenishing Robot

Acquiring and Delivering

Objectives

Build a line following robot that eliminates the need of a microcontroller;

Digitally control the activation of the robot’s movements;

Minimize human intervention;Adapt the mechanical aspect of the robot so it can

be integrated with the base (Team B10);Solder all components into a single circuit;Minimize the use of pre-manufactured and pre-

programmed circuits.
