A remote wireless hydraulic cab preferably includes a cab member, a hydraulic sensor block, an electrical bulkhead, a cab bridge controller and a cab transceiver. The cab member preferably includes a cab enclosure, two hydraulic joysticks, two hydraulic treadles and electrical equipment. The hydraulic sensor block includes a sensor block and a plurality of hydraulic pressure sensors. Hydraulic lines from the joysticks and treadles are connected to the sensor block. Pressure measurements from the joysticks and treadles are sent from the plurality of hydraulic pressure sensors to the cab bridge controller. The cab bridge controller sends signals for wireless transmission through a cab wireless transceiver to a frame transceiver. The electrical equipment is supplied with electrical power and transmits signals through the electrical bulkhead. Electrical power to the cab enclosure is supplied through an electrical generator and hydraulic fluid to the joysticks and treadles are supplied through a hydraulic pump.

Remote wireless hydraulic cab

An adaptive joystick preferably includes a rotatable cylinder bar, an outer base ring, an inner ring and an industrial joystick base. An adaptive controller receives an output from the adaptive joystick and outputs a control signal to a valve solenoid to control a hydraulic cylinder. Angle, depth and pressure sensors are preferably used to monitor a position of the hydraulic cylinder. The sensor outputs are fed into the adaptive controller. An inward wrist curl of the rotatable cylinder bar combined with a forearm pull rearward of the outer base ring are used to cause a digging motion. An outward wrist curl of the rotatable cylinder bar combined with a forearm push forward of the outer base ring are used to cause a dumping motion. A hand movement to the left is associated with swinging the excavator left. A hand movement to the right is associated to swinging the excavator right.

One-handed joystick with adaptive control

A joystick having increased control functionality preferably includes an industrial joystick base and a rotary upper handle. The rotary upper handle preferably includes an outer base ring, a rotatable ring, a position sensor and a base portion. The outer base ring extends upward from the base portion. The base portion extends from the industrial joystick base. The rotatable ring is rotatably retained in an inner perimeter of the outer base ring. The position sensor is retained in a sensor cavity formed in an inner perimeter of the outer base ring. The rotatable ring preferably includes a ring portion, a rotatable cylinder bar and a compression spring. A center contact and a peripheral contact are retained in an end of the rotatable cylinder bar and make contact with the position sensor. The motion of the rotatable ring and the rotatable cylinder bar are sent to a ring controller for processing.
