Microcontrollers Status lights Battery Transmitter Serial Cable
Power • Self-Explanatory
Motor • Use shafts, bearing flats, and thin screws • Only Continuous Motors • Different from usual DC motors
Sensor • Limit • Creates a range of motion • Shaft Encoder • Counts rotations of wheel • Sonar • Measures distance
Transmitter • 6 Channels • “Trimming” • 9 Volts minimum
Transmitter • Crystal: Certain frequency • Connect to microcontroller with cable
Hardware • Parts that keep the robot together • Screws • Nuts • Standoffs • Shafts • Shaft Collars
Screws & Nut • Thick: • Most parts • Thin: • Motors • Rack Gears • Tips: • Push down and twist • Otherwise, they become stripped • If possible, tighten from nut
Standoffs • Very useful support • Columns • Press Limit Switch • Use regular screw
Shaft Collar • Tighten things in shafts • Stop motors and wheels from sliding • Tips: • Never unscrew too much • Not too tight • Use thin wrench
Tips Summary • Shaft Collar • Never unscrew too much • Not too tight • Screws • Push down while twisting (Becomes stripped) • Zip Ties • Only at end
