    This looks very interesting for G-Seat applications. I'm probably going to give it a try.

    Here too on Amazon.co.uk & slightly cheaper:



    It's a bit slow at 0.5s/60 degs but with so much torque, the point of leverage can just be extended. I figure its kind of equivalent to 100kgcm with 0.1s/60 degs, but what I'm hoping is that by running at 24v it will cope with a load better than a 7.4v servo.

    Arduino should drive it shouldn't it?

    Well it's encouragingly chunky. I emailed the suppliers to get dimensions. Compared to my KingMax 65kgcm, which is 66mm*30mm*57.5mm, this one is 135.5mm x 96.5mm x 67mm.

    Is it crazy to think of using this for a platform, not just a g-seat? With a 10cm lever, 120 degrees of movement would give 20cm vertical displacement in 1 second and it could cope with 50kg. I don't know what the real speed would be with a load of 50kg, but on a 6DOF and a platform weight of say 150kg each would only need to lift 25kg.

    Any comments on my numbers?

    Parameters are great. But I think there can be issue with overheat in closed case.

    Good point. I just found this which might be better. Its only 110kgcm, but the speed is 0.12s/60 degrees so it moves almost 5x quicker than the sealed one, making it somewhat equivalent. Its also cheaper and open to aid cooling.

    Development of servos seems to be fast moving at the moment, no doubt driven by robotics. I think they could have a useful role in low-cost simple-design motion platforms - your DofReality kind of thing in fact!
