Quick recap, “the mission”: we want to build an affordable open source industry quality robot arm. We think we can make it out of low quality components but stick an accurate sensor on the end effector (the ‘hand’) and sidestep the huge costs of precision mechanical components. Web cams are cheap, and people already own computers capable of the required visual processing, so we think that optical localization is a better strategy for many applications that researchers, entrepreneurs and engineers might like to do – if we can get the optical localization accurate enough.
Last time we calibrated our £18 Microsoft LiveCam 3000, and experimented using Vision Visp’s moving edge tracker. We found that the moving edge required a highly accurate object and we could not build one to the 0.1mm accuracy target we set ourselves. Furthermore, the actual moving edge tracker was not particularly CPU friendly, so we decided to pursue a different strategy this time.
This Friday, 18th May, is our monthly music night, starting from around 8pm in the lab. Come along to talk about music, hacking, and make some noise! The month before last I wasn’t there, and I missed out on Andrew and Tom’s resistive fabric synth, and James and Matt of Madlab making instruments out of jelly. Don’t make the same mistake I did: make sure you come to the lab on Friday!
This month Gareth is going to talk about using cSound to create sounds on your computer, and I hope we’ll have some live performances from anyone who fancies it. There’ll also be the usual blether and working on hacks throughout the night.
Bring your own hacks, ideas, news, and performances.
Hope to see you there
The guys at Shropshire Linux User Group have been busy designing boxes to put your Rasberry Pi in. Well, that is if you are lucky enough to have one. I don’t think I am far enough along the queue to get to place an order yet Damn I want so bad, I want one more than I wanted Lego when I was (twenty)8.
I am sure we will be cutting a few of these on our laser in the coming year!
