A-pod program : strange behavior

guichome · September 26, 2013, 2:50pm

Hello,

I’m using the A-pod electronics : SSC-32-V2.07Alpha1A-EGP and the botboard II with the latest A-pod program in the atom PRO 28. I made the mechanic parts myself.
I managed to configure the neutral positions of the servos with Lynxterm (V1.11).
When I turn on the robot, it goes to the neutral position then when I start the PS2 remote, the tibias are parallele to the ground, pointing to the outside.
The second issue I’m experiencing is that when I press triangle on the PS2 remote, the body goes the farther possible from the ground instead of switching from 35mm from the ground to the walking behavior.

Programme in BAP 28 : apod_ps2.prj
Phoenix_Config_3DOFAPod.bas
Phoenix_Control_ps2.bas
Phoenix_Core.bas
Phoenix_Driver_SSC-32.bas
Version ofBasic Micro Studio : V2.0.0.18

Thank you,

Guillaume

Can you post an image of your setup? Also, did you mechanically copy the design instead of rotating one or more of the servos by 90 degrees or 180 degrees?

Hello
My setup is different because i changed the servos and i machined the tibias

This is my temporary installation (on a support and connect just three tibias for the test) :

When I press the triangle on the ps2 remote, here’s how the tibias are positionned :

And when I try to move the robot, the tibias don’t move correctly!

Sorry for my english but I’m french.

I hope you will go to help me succeed

If you want more explications, don’t hesitate to contact me

Thanks for all

Check how the servos are mounted - are they at 1500us when pointed straight down?

Let’s resolve the first issue first and see if that affects this one.

Here’s how the servos are positioned when in position 1500US !

,
it’s necessary to activate “initial to pulse offset” and “initial pulse width” in Lynxterm ? Otherwise starting the robot, tibias remains at the same position

Thanks

it would not be a program error in the bot board because the SSC-32 work correctly !!

Thanks for all

Good starting position. So what did you mean when you said “The tibias don’t move correctly”? Can you upload a video?

“The extension mov is not allowed.”
