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