=== Control of Robot Arm === | |||
Someone on the public mailing list sold me a pair of robot arms for $150. It was a sweet deal so I took them. One of them has a controller to move it manually. The other one came with a handful of stepper drivers. | |||
* So far I've gotten the one with stepper drivers to move all its joints at the same time using an Arduino and a fancy stepper driver controller library. | |||
* I'm working on adding limit switches to each joint so I can move them to a known position at power on. So far I've managed to install two. | |||
** The first one was on the elbow. | |||
** The second one is on the shoulder. | |||
** I'll probably do the base next. I've had a few suggestions for how to do it. | |||
** The wrist will probably be the most difficult. I'll probably actually attach the switches so that they'll be triggered by the brass turnbuckles on the cables. | |||
** The gripper already has a switch for detecting when it's closed, so I can use that. | |||
* Once I can home the joints, I can add additional control software on top. I plan on working out the full inverse kinematics, then programming the bot to do things like block puzzles. | |||
* I may even add a camera above it for some more fun! :-) | |||

== Sidelined projects == | |||
These are projects that I'm technically still working on. I've realized that in order to actually get anything done, I need to focus on a single project, finish it, then work on the other projects. So I'll get back to these projects once I finish the project in the '''Current Project''' section. | |||
