I haven't made any of these yet, but I'm thinking of making one on the summer holidays.
What you have there is a master/slave robot arm, you could probably make one easily using potentiometers for angle sensors and servos for actuators and an Arduino for control. If you're looking to make one on...
The problem with bicycle hub motors is that they're optimized for higher speeds. If we use a motor that's optimized for bicycles that means that it's efficiency at lower speeds will be reduced. Hence we'll need a more powerful motor and we'll need more batteries, increasing the weight and cost...
Hi,
My classmates and I are doing a final project (undergraduate mechanical engineering).
The project is for a motorized walker for senior citizens living in hilly areas.
We are looking for an electric hub motor that's optimized for low speeds (up to 100 rpm,about 180-300w) and we are having...
