I would really like a six-axis force/torque sensor for my robot, but I just can't afford one. I was thinking about making one of my own.
I have experience using strain gauges, but I can't work out how to arrange them so as to create a six-axis force/torque sensor.
- Is this something I could feasibly make myself?
- How do they work? What is the theory behind them?
I'm curious to know how they work, even if it's not feasible to make one myself.
Just to be clear, I'm talking about force / torque sensors, like this ATI Nano 17:
I am not talking about accelerometers or gyros, or MEMS IMUs.
