Use puppet as an example of controlling Baxter using joint velocity control.
Start the puppet example from an RSDK terminal session, specifying the
right arm as the "puppet", ex:
Grab the other arm (e.g. the left in this case) at the cuff and move it around using '0 G' mode to puppet the arm specified on the command line.
There are three modes of control for Baxter's arms, joint position, joint velocity, and joint torque control. This example will mirror any relative movement (joint velocities) on one arm to the other in 0 G mode.
For more information on Baxter's arms, see Using the Arms.
See the usage on the command line by passing puppet.py the
-h, help argument:
limb - Specify the limb to puppet: left or right
-h, --help - Show this help message and exit
-a, --amplification - Amplification to apply to the puppeted arm (ex: - setting to 0.5 will move the puppeted arm at 1/2X the velocity, setting to 2.0 will move the puppeted arm at 2X the velocity)
See the API Reference page for details.
