Just thinking of potential uses for a small robotic arm, so far I'm coming up with some very needed tasks, thanks to Obama and his supporters, but they aren't politically correct.
Reloading assistant, grab primed brass from tray, add powder, place in reloading press, grab bullet. Operator, cylinder, or motor actuates press.
Attach a gun and machine vision camera, have robotic arm automatically aim at potential threats, use manual fire control after viewing image of the target.
Dangerous jobs such as assembling fireworks or other dangerous or explosive chemicals.
Loading and unloading cnc machine, perhaps even too changing for machines without automatic tool changers. Should be great for AR-15 and AK-47 receivers!
Or, the most anti-liberal idea yet, learning a skill to get a (gasp!) JOB!!!
Ok, now to be serious, I'm interested in trying to write an updated control software using kinematics to position various points about the end efector. One idea is to position to the center of one of the "claws" on the gripper, rotating the gripper would cause the robot arm to move about to keep the "finger" in position while rotating, such as if you wanted to insert the claw into a hole to grab something. Sounds like interesting and challenging programming anyway!
