Dont bother on that Vader arm. I bought one of those a year or so ago. There isn't any part of it you can mod as it is made very cheaply. As a model for inspiration maybe but it has no hack value.
As far as the gripper, I think even if it turns out to be slow to close and open, it is possible to mod.
I've been thinking about getting a pair myself but was concerned as to the proprietary connection on the connecting wire.
how would you wire this up? replace the tip with a servo wire or cut off the connector and connect the wires to a sabertooth controller?
Judging by the small size, I doubt you need many amps.
These are the motor specifications from Makeblock:
Code:
micro switches might be an option but i'm not sure how you would mount those on the gripper in any way that wouldn't interfere with picking up objects.
I cant see the video from my work computer but judging by the picture you could try a microswitch for the full open. Another option for picking up something are pressure sense pads on the tips of the claws and flex sensors across the back of the "fingers" to sense the amount of open/close.
it seems weight is 0.35 pound .
