Connected the Armdroid to my Bench Power Supply - unfortunately, I don't have an original power supply, voltage was set around 15v and switched on :
No smoke, a promising start...
You can see the arm is still dismembered for re-stringing and repairing mechanical problems.
You'll notice when the motors are ideal, little more than 3Amps is drawn - this actually drops when motors are spun because of the fact they are always energized:
Temporary connection made to the Power Connector terminals :
A discussion on the power connecter can be found at the Society of Robots
I was amazed to find out Maplin actually stocks something useful !
Hand controller connected, cable clamps prevent accidental pulling out - an enhancement made by the University and seems a sensible idea :
And so here we go....
All stepper motors responding to Hand Controller
I put stickies on the motor shafts in this video - makes things easier to see what's happening:
