The command :
dxl_io = pypot.dynamixel.Dxl320IO('COM3', use_sync_read=True)

works fine :
%timeit dxl_io.get_present_position((1, 2, 3, 4)) -> 100 loops, best of 3: 6.9 ms per loop

but using "sync_read": true in the json configuration file raise error :

WARNING:pypot.dynamixel.error:Communication error after sending DxlSyncReadDataPacket(ids=[1, 2, 3, 4], address=46, length=1)

What means this error ?? Why to motors 254 ??

For the software the module can not be named poppy_4dof... because the function camelcase_to_underscore(name) in poppy.creature.abstractcreature.py return a module named poppy4dof_arm_mini althought it should be poppy_4dof_arm_mini.

def camelcase_to_underscore(name):
s1 = re.sub('(.)([A-Z][a-z]+)', r'\1_\2', name)
return re.sub('([a-z0-9])([A-Z])', r'\1_\2', s1).lower()

I don't see a simple solution, just avoid to use number just after underscore in the name of the creature.

Cuttings for brace are missing in the pdf file.
It could be better to put diameter hole to 3.9 mm and not 4.1 because the laser has 0.2mm wide (to much clearance).

@matthieu-lapeyre How did you process to make the PDF file for laser cutting from the onshape drawing ? I can update the doc. with the cutting for the brace.

Hi! I just installed Poppy Ergo Starter using:

curl -L https://raw.githubusercontent.com/poppy-project/raspoppy/master/raspoppyfication.sh | bash -s "poppy-ergo-starter"

I can use Poppy with Jupyter, but I can't move it using Snap! I can only get the motor list, get current position, and change LED colors, but I can't move the motors.

How can I use Poppy with Snap?
