I am building a line following robot, and I can't decide which motor would be the fastest. Below I have posted a table of the Micro Metal Gearmotors from Pololu Robotics and Electronics. Here is a product listing and chart of all the motors. Please post the product name, and a link if possible. Thanks! (If you have any other ideas to make a low profile robot awesome, post it in the comments below)
- Gearbox Shaft Only means it is the shaft directly from the motor
- Gearbox & Motor Shafts is an extended shaft
