When I try to run this, it crashes:

rosrun basic_head_api head_ctrl.py
Traceback (most recent call last):

    from ros_pololu_servo.msg import servo_pololu
ImportError: No module named ros_pololu_servo.msg

When I look at the sources, I see that there is no such message: it was deleted long ago, by Jamie Diprose. The available messages are currently:

MotorCalibration.msg MotorCommand.msg MotorStateList.msg MotorState.msg

To be clear: the core issue is the the hanson robotics fork of ros_pololu_servo was never merged back into mainline, and mainline then changed in an incompatible way ...

Vytai,

You may call me an idiot for doing this .. but: I am trying to staple eva_behavior onto either blender_api or onto robo_blender. I notice that eva_behavior generates messages that this node seems to listen to, and NOT messages that robo_blender listens to.

So, just so that I can play with eva_behavior for a while, I am going to add a shim that converts these messages into the old-style arther robo_blender messages. That is, when the /make_coupled_face_expr is received, it will publish the /cmd_exprssions that robo_blender wants. I think this is a reasonable thing to do ... but ... is there some easier way? Is there some existing node that already does this?

Once the https://github.com/hansonrobotics/pau2motors/issues/5 implemented. Need to update the expressions to be defined in PAU.

Somehow, this and pau2motors have or are going to have some sort of interaction, right? How?

Will this also be used to drive the blender api?

More generally, How do you run this? What are the pre-requisites?
