80   Interface for Kinova Jaco2 robot.
81 
82   This class is a wrapper over Kinova Jaco SDK that could be downloaded from Kinova Robotics
83   <a href="https://www.kinovarobotics.com/en/knowledge-hub/all-kinova-products">software resources</a>
84   by following the link under `Gen2 7 DoF > SDK 1.5.1`.
85 
86   It allows to control Kinova Jaco2 robot Gen 2 with 7 DoF, 6 DoF and 4 DoF.
87 
88   To select the degrees of freedom corresponding to your robot use setDoF().
