Hi Guys
Please help a newby
I would like to install a gyro in my bot, I was amased at some of the videos seen with a working gyro.
Now the bad side I am not the best at programing . is there a kit + writen program Ie addon to existing Humanoid I could purchase Please Please Help

I just started selling a six-axis IMU (which actually includes 3 gyros).
You can get values from it using the BCP, although I haven't figured out yet how you would actually use them from there.

I know limor and a bunch of people have designed and built a more general I/O board that can interface to cheaper one-axis gyros - look at these threads:

Hi Jon
Thanks for your comments , you guys are the best. what Iam looking for is
1 the hardware in laymans terms Plug this to that
2 an existing bioloid program changed to suit new hardware
I know i may be a bit thick here but i'am not as good as you guys and some of the tec talk you use is beyond me at the moment

For #1, using my IMU will do the trick. You plug it in to a free bus plug, and you can access the data from it directly, the same way you access data from AX-12's and the AX-S1.
For #2, well, you're pretty much on your own right now. Having the raw data is one thing, being able to do anything useful with it is entirely something else. A lot of the other non-bioloid humanoids use simple helicopter-type gyros, which basically take a servo drive pulse and input and output a modified servo pulse. With my IMU, you get back numbers, which have to be then interpreted somehow.
I have a pretty good idea of how to do that with my setup, but I'm not using the CM-5 or the BCP. I talk to the devices on the bus directly from a PC, and I have a lot of memory and a lot of CPU to run more complex algorithms, and dynamically alter the motion profiles to take into account information from the IMU and other sources.
I'm hoping some of the people who end up using my IMU with the BCP will figure out a good way to use it.
