  2. RefreshmentReplenishingRobot Acquiring and Delivering

  3. 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.

  4. RRR Our Circuit!

  10. RRR 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

  11. RRR

  12. RRR Problems/Challenges Encountered • Triggering of circuit at specific moments; • Integration of digital circuit without use of DAC and ADC; • Minimizing total size of circuit for soldering.

  13. RRR Progress Completed • Entire robot circuit; • Most of robot enclosure. To do • Finish enclosure; • Make path and calibrate robot with it.
