Final Year Studio - Development - Large Servo Test

With the small servos struggling to cope with the momentum and weight of the acrylic screens I thought it may be a good idea to test the torque on some large servo motors. As you can see above they operate in exactly the same way as the smaller ones but without attaching anything to them they already felt slightly loose in inside. So to finally test to see if they would work with out wobbling I attached a screen to the servo arm and tested a single servo unit. Unfortunately the weight was still too much, and still vibrating occured.

In testing this though I came up with a possible solution. My theory is that if I can get a light enough semi-circle screen to attach to the servo arm and use a two way switch to turn the servo motor off once it arrives at its specified angle, I may be able to salvage a workable screen. Possible materials to experiment with for the servo screen could by polystyrene or the 'Oasis' blocks used by florists in flower arranging. Both highly durable very light materials that wouldn't put too much strain on the servo motor and its arm.
