SUMMARY
I.Ca.Ro. (Innovative Cartesian Robot) is the prototype of an innovative parallel kinematics robot developed by the Machine Mechanics Group. The robot kinematics provides the mobile platform with three degrees of freedom of pure translation. This feature is of great interest for a wide range of applications. One of the most interesting performance is the thrust of 4300 N that the robot can develop downwards in a vertical direction, whereas in the same direction the maximum speed and acceleration are respectively 1.06 m/s and 9 g. The control system is implemented on a dSPACE board: a PID position control currently allows to drive the robot end-effector along desired trajectories, whereas an active impedance control allows an interaction of the manipulator with the external environment.
