Thanks. I was going to post a link to the āfirst stepsā video clip, but then I did some work on the stepping sequence, cleaned it up a bit, etc., and figured Iād post a clip with a somewhat āprettierā gait than that one.
That, and itās just a raw clip from the camera - I need to see about firing up the editing software, and shooting some cleaner video.
From the video information:
āControl is through a Bluetooth module from SparkFun Electronics, feeding commands to a Lynxmotion SSC-32 servo controller board.ā
Yes, as mentioned above (and in the comment section), the remote side is a BlueSMiRF module (with RP-SMA connector and 2.2 dBi ārubber duckyā antenna). The base side of the link is an MSI StarKey USB bluetooth dongle, connected to a notebook thatās running the SEQ software.
After working with the BRAT configuration a bit more, Iām pretty sure that Iāll be adding at least a couple more axes to get a little more flexibility out of it.
Iām still pretty ambivalent about walking as a means of robot locomotion; itās just too complex and resource-heavy for my liking, but that wonāt keep me from playing around with it for a while. If nothing else, a walker - particularly a biped - has a lot more āgee whizā factor than most other designs, since coaxing a machine to get up and walk around is something thatās recognizably difficult to do, even if you know nothing about electrical and mechanical control systems.
Besides: Itās an SES project. If I decide that Iāve āplayed outā on bipeds, I can always disassemble it and turn it into something else later.
