    The reason I have it structured in its current way is so SLAM and pointclouds are as accurate as possible. Telemetry is spot on in gazebo and Rviz to what is happening on the actual robot. If you...

    The arbotix-m is not like a raspberry pi or similar boards. You can't connect a camera to it.

    Re: Hexapod in vertical surfaces

    I believe the problem is on a vertical surface ALL the weight is on the coxa's including the legs themselves. Where on horizontal that load is supported by multiple servos.

    Re: Hexapod in vertical surfaces

    Are you sure it isn't an overload due to trying to support all that weight? Dynamixels shutdown if it exceededs its torque limit.

    No, not without a firmware hack. It will destroy itself if it goes over that. That is why it is there. I'd suggest a small fan blowing into the vents.

    Constant on means there is something wrong with the servo. How did you hook this all up? Do you have any pictures of your setup? did you make your own wires or buy?

    Re: PhantomX controlled by a Raspberry Pi

    A USB2AX is plugged into the raspberry pi USB port. The same way an Arbotix-M or Arbotix Pro is. Essentially all three serve the same purpose. They just have various additional features.
