I’m working on a Wall-e toy conversion making it into a Spark controlled robot over OSC. I’ve basically got everything working, however I have one problem to solve.
If you watch the above video, you may notice that when I trigger some of the servos, they actually interfere with some of the other servos, causing twitching or movement when they shouldn’t (A good example is when I trigger Wall-e’s left hand track, the right hand track also turns when it shouldn’t).
On this project, room is an ABSOLUTE premium so I can’t afford to have separate power supplies so I need to find a way to cut out the chatter as best I can.
I’m not sure if how I connect up all the servos is a problem, as I use a little board to plug them all into to share the power and then send the signal lines to Spark. The Spark is also powered off the same power rail.
I’ve heard adding capacitors in certain places might help, but I’m not quite sure of those places. Can anyone suggest any mods to my power rail I can make to try and minimise the chatter going on?
