The robot arm is expensive because it needs precision hardware (backlash free bearings/gearing). Your idea also requires precision hardware to move the sphere.

- ccozan 9y agoActually besides 3 step motors ( for rotating in three axis ), rubber wheels to hold the sphere and a sensor to measure the water level, I don't think you need more. What I don't know is how much water you need, probably this can also be computed. It's a better idea than dipping with a robot arm. And also faster.
