3. 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. RRR

6. Light Sensor RRR

8. 4066 Quad Bilateral Analog Switch RRR

10. 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 RRR

12. 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. RRR

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