USB Robot arm control with Python and Raspberry Pi
I was asked recently if the USB robot arm could be programmed - I knew the answer was yes. The Arm came from the CBiS Education Robot Arm kit ( http://www.cbis.education/Product-Details.aspx?prodid=2 ) which comes with a Raspberry Pi and SD Card with software to control the Arm. So the question has become - How do I program it in Python from scratch ? Well, the honest answer is I don't I use what others have done before. A good starting point is this site http://www.wikihow.com/Use-a-USB-Robotic-Arm-with-a-Raspberry-Pi-(Maplin) , it gives most (pretty much all) of the answer, including where to get the pyusb library need; setting it up (be careful don't use the zip file but the tar.gz version - you might need to scroll down the screen to do this) and an example. A second source that was very useful was http://notbrainsurgery.livejournal.com/38622.html?view=93150#t93150 which contains an explanation of the 'triples' (for example [32,0,0] ) used to select w
