Hi Taylor and community,
I am a robotics and ML engineer. I somehow landed on this forum after watching Taylor’s video Starting a Business in Silicon Valley: A Personal Story. There are interesting discussions on the making a rover and the VESC. This seems like the right place to have discussions on interesting robotics problems. I have been thinking about a problem and I wanted some help with it. I am not sure if this is the right place to ask. Forgive me if this isn’t.
I want to build a 4WD robot that can travel vertically by pushing against opposite rails. The wheels push against the rails and generate friction, the robot moves upwards as the wheels rotate. This is the side view that I am thinking of:
If one side moves faster than the other then the robot would loose grip and fall down. I have to ensure that the wheels on both sides rotate at the exact same speed. How to maintain the same speed on both sides?
