DC Gear Motors

DC Gear Motors – Obstacle-Avoiding Robot

The DC gear motors provide the driving force for the obstacle-avoiding robot. For a beginner 2WD robot, a 6V 100 RPM TT-style DC gear motor is a good choice because its gearbox provides useful torque at a relatively slow and controllable speed. The motor is commonly used in Arduino-based smart cars, line-following robots and obstacle-avoiding robots.

A suitable budget model is the Generic 6V 100 RPM DC Gear BO Motor – TT Dual Shaft, which is approximately US$0.61 using an illustrative exchange rate of about BDT 123 per US$1. The motor operates at 3–6V and provides approximately 100 RPM at 6V.

Another option is the China 100 RPM 3–6V TT Dual Shaft DC Yellow BO Gear Motor.
