Years ago, while in middle school I noticed one of these robot arms in my technology class in junior high. It looked very cool, but I spent all of my time on Lego Logo projects. Fast forward to recently where I found one of these old arms on EBay. I was lucky enough to have the winning bid. The lot only contained the arm (no power supply, interface cables, manual, etc). Soon after that I found the training manual for the arm at an online used book store. Fortunately, this book contains the schematic and all sorts of technical details about the arm.
The plan:
- Hook up an old ATX power supply to the arm (the arm requires +5V and +12V)
- Start figuring out the parallel port protocol. Will try using an Arduino. If that doesn't work, will grab a USB parallel port adapter.
Well, I've gotten nowhere. Unless you count moving the arm from place to place. I've powered it up before using an ATX power supply, but that's about it. I have the technical manual for it and can copy / post the schematics if it's helpful. Heck - this is making me thinking about dusting it off and getting to work!
You should dust it off! Fortunately, I was able to find the manual, too. Before I moved houses I had my robot working and receiving commands through an arduino. It can only perform routines I’ve programmed right now, not real-time control.
I need to pull it out again and get it set up, but I did document some of how I got it working. It’s the only project I have up on hackaday so if you’re interested you’ll be able to find the documentation I put up. Happy to chat about it!
hey, where are you at with this project. I have the same robot and would totally be up to compare notes
