I know what you mean about being busy. You seem to be going down the same thought path as me, small controller for serial comms and maybe conventional gyro or accelerometer. You can get good 3-axis ones now too.

Keep us posted on your progress. I'll keep you updated with mine.

I working on a Gyro expansion for the Bioloid over serial interface but it take time I am very bussy at the moment.
I look for new Gyros at the moment and a small controller (Atmel) also a 3 Axis Acceleration sensor.

The standard Bioloid programming environment has no support that I can find for gyro's, however, you can program it in "C" so you could write your own code that does.

The second problem is that, without modification, there are no external I/O connections on the Bioloid controller. Such a connection would be needed to interface to a standard servo type gyro. The only connections that are available support the serial I/O protocol that is used to communicate to the intelliget servos and sensor module. It should be possible, however, to produce a unit that connects to the serial port on the controller and interfaces to a standard gyro. You would have to write some code for a microcontroller to do this though. The Bioloid programming environment may well then support gyros, an intelligent gyro.

These things are all very exciting for me and are all avenues I will be investigating when I get my Bioloid, however, I guess they may not be do-able for everyone.

There is no easy way I have come across yet to connect a gyro to a Bioloid but I am working on it.

The big attraction for me is that the Bioloid kit is like advanced Lego to me, you can make all sort of things with it. If you just want a humanoid go for a Robonova.

Sorry, I don't have a bioloid, still I am interested in Bioloid but I cannot
convince myself that Bioloid can have the important gyro feature.

Do you have a Bioloid then?

If the sampling rate is fast enough,
one can simply use a acceleration sensor to find the
angle displacement and the 1st and 2nd deviation of it,
making the corresponding compensator.
In control theory, it work.

My robot do not have program ability, so I cannot try.

I don't have the Bioloid yet but am planning to get one when Robosavvy get stock. I was wondering if anyone had managed to interface one to a gyro yet.

I guess some of the Mega128 ports will have to be brought out to external connectors so that a gyro can be connected. Then suitable C code will need to be written to utilise it. That is all a long way away for me at the moment but looks like an interesting challenge.

I like the Bioloids flexibility but don't like the lack of easy expansion capabilities that the Robonova has......

The Bioloid kit I have (purchased from Robosavvy) does not have a gyro with it as standard. In addition the interface to the processor is via a TTL level serial connection at half duplex running at a rate of 1 mbps. Anything you wish to interface to the Bioloid kit will require an interface or interfacing hardware that will allow it to communicate at these rates and using the published Robotis protocol.

I am unaware of any gyro on the market that can interface in this manner (but am more than interested if anyone else has come across one).

hope this helps

Has the Bioloid a Gyro onboard ???

Or you have a external gyro???

Please let me now.

Hi

Has anyone managed to gyro stabalise a Bioloid yet?
