what would you guys say are the main part for building an Arduino robot that every hobbyist usually uses for electronic components n and sensors and motors
You’ve already used many of these I think. Robot car chassis, Gear motors, compatible Wheels, Motor driver modules L293/L298, SG-90 servo, ball caster, On/Off switch, Arduino compatible battery pack. These are common parts. Choice of Sensors depend on the features of your robots. For example, IR transmitter and receiver packs for line follower and maze solver robots, SONAR for obstacle avoiders, HC-05 bluetooth module for android controlled robots, Flame sensors for fire fighters and the list goes on…
