Hi, My goal is to create a camera operator that replicates shots that I demonstrate to it. It needs to go 1-1.5 metres a second - bonus if it can go up to 3 m/s. For that in my research and measuring the area required, I need to create a 3 axis system at least. The X axis needs to be 7.2 Metre X 2 Y axis at 3.53 metre X 1 Z axis at 2.34 metre X 1 The camera equipment (approx 3-4kg) sits on a moving carriage with a breaking motor on a stable Z-axis . It would be belt-driven with stepper motors on the other two axis. For the long length, I would join two rails with flat butts together with one inversely positioned so the gaps are not the same. I would use a displacement sensor to collect position data. Now I need help, I am not sure if any of this is right for this length and weight. I have discussed this with a couple of other people who say that the load on the x-axis might be too much for the belt since the length is long and the speed is this fast and. That instead I should use steel ropes and a pulley mechanism. It would be a bonus if I could have panning and tilting. What are your thoughts? I would deeply appreciate your help with planning this out. Where possible please include the components needed and their configuration. Any additional help is also appreciated.
