As you may know, I'm building a humanoid robot. I'm looking for a good gyroscopic sensor that could fit into my robot (the new back allows a bit more space, so if it's bigger it could fit) and is easier to code (I need it to stabilize the robot and tell it to get back up if it falls over). I've been looking at a gyroscopic 3-axis sensor at radioshack: http://www.radioshack.com/product/index.jsp?productId=12310182 Would this be easy to work with? Thanks a bunch!
EDIT: Also, this is the distribution block i'm getting for my 4 micro servos. How would I connect the ground/power to this and the signal to the EZ-B, and the battery to the distribution block? Once again, thanks. http://www.radioshack.com/product/index.jsp?productId=2103983&locale=en_US
The control signal is not part of the power terminal block and is connected to a digital port of the EZ-B using the white lead from a servo cable to your servo.
Terminal block electrically should look like this:
-----(+)-----(+)-----(+)----(+)----(+)----(+)---------> Positive battery
-----(-)-----(-)-----(-)------(-)-----(-)-----(-)---------> Negative battery
i was thinking to do whit desame thing but whit the robi robot.love to see it.
tip the cm-510 is the best controller for bioloid.you can refirmwire servo's and controllers.
whits cm-5 and cm-530 dont do.you can use a 510 whit the comprehencive too,
then you have ports for touch sensors or other.
I have no gyro advice or experience. Sorry.
But just to be clear, you're trying to connect external power to the servos so they don't draw from the EZB, correct?
Here's the project thread.
Ez-robot Humanoid Project
I've never used a gyro but I'm guessing it would plug into the board but it may require a little bit of work. Kind of like an H-bridge does to connect it the the ezb v3
Back to the V4...where the hell is the manual and the specs? seems weird to sell an electronic device without the electrical specs, It might be just me but I for one will never purchase and electronic device until I know what the specs are, I know , I know, the EZ-B V4 is wonderful, there marvelous there the best thing since sliced bread but its an industry standard to provide the specs before purchase not after
Anyhow yes, split the wires on the servo's, provide 6v to them and plug the signal wire to the v4 outputs, the accelerometer has analog outputs that would go to the v4 analog inputs ( 3 of them ) and they can be powered by various voltages depending on which one you buy.
On each output the accelerometer outputs a variable, on the one i'm using , from 0 to 512 for one direction and from 0 to -512 for the other direction.
It's a simple matter of using those numbers in a variable in EZ-B to manipulate the servo outputs.
I know i ramble on but I do have a Hexapod that runs 20 HS-5645MG servo's that is programmed with very similar scripting as EZ-B but uses an Atom BotBoard and a SSC-32 serial control board with the aforementioned accelerometer from Spark Fun.
It has also been discussed and explained in some depth in the forums here amongst bits and bobs in other topics.
It reminds me of another thing I rant about , NEW MOVIES , like coming JUNE 2015 , hell I may be dead of old age by then!
Well for now I'll continue with my V3 EZ-B and my Atom BotBoard.
