Pressure feedback for electronic joystick

An assembly for operating a tool, wherein the assembly comprises:

• a hydraulic system having a hydraulic tool drive for moving the tool;
• and
• a control system including a joystick and an electronic controller,
• wherein the joystick includes a joystick handle configured to be manipulated by an operator for indicating desired movements of the tool and joystick sensors for sensing movements of the joystick handle, wherein the joystick is configured for providing control signals to the electronic controller based on the movements of the joystick handle;
• wherein the control system is operable to provide feedback to the joystick handle should there be an increase in hydraulic pressure sensed at the hydraulic system related to the tool.

A method comprising:

• providing a tool and a control system for controlling movement of the tool, the control system including an electronic controller and a joystick connected to the electronic controller,
• the joystick sending control signals to the electronic controller,
• the electronic controller controlling supply of hydraulic fluid to a hydraulic tool drive to move the tool based upon the control signals from the joystick, a pressure sensor sensing a hydraulic pressure at the hydraulic tool drive as the tool moves;
• and
• the electronic controller providing a pressure feedback signal to the joystick to provide a feedback force based upon the sensed hydraulic pressure.
