Hi all, hope this is the right place to post. I am looking to build a ‘base’ that will carry 100kg, i.e. a person. The part I have no idea on is the motors, wheels and brackets to affix to a board. The motors will be driven by a motor controller, and the device powered by a 12v/60Ah lead acid battery. What motors do I need and what wheels do I want? Rather than two rear wheels for drive, and two front wheels on servos, I’m looking for the device to be able to turn on the spot. Perhaps 1 motor+wheel on the left, and 1 motor+wheel on the right that can turn in either direction via a motor controller, and then just one roller on the front and one on the back for it to balance straight on. Any help much appreciated! Ty!
Hi adamsinfo,
Welcome to the RobotShop Forum. You have come to the right place. We suggest starting with the Drive Motor Sizing Tool. This will help you select the right motors. We can save you a bit of time by drawing your attention to the CIM motor and associated gear downs. You can get away with one motor one each side (each connected to a wheel) and two swiveling casters at the front (so the weight is between the four wheels). To connect the motor to a wheel, you will need a hub, a key (appropriate size - please check) and two set screw or clamping collars and of course a wheel.
Hope this helps,
