Objectives l.jpg

RRR

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.

Digital Controlling Logic

  • Logic gates truth table.

« Pressure » Switch (A)

« Position » Switch (B)

No refreshment on robot; Position = Base. Nothing

Refreshment on robot; Position = Base. GO!

Refreshment on robot; Position = Couch. Nothing

No refreshment on robot; Position = Couch. GO! back
