A one-handed joystick for excavators allows an operator to make all necessary motions with a single hand and arm for manipulating an excavator tool. The one-handed joystick includes a rotatable cylinder bar, a rotatable ring and an industrial joystick base. The rotatable cylinder bar is grasped with a hand. The industrial base is moved front to back, or right to left. The following are preferable hand/arm motions. A downward hand curl is associated with a bucket digging motion; an upward hand curl is associated with a bucket dump; a forearm forward push is associated with a boom/stick extension; a forearm reward pull is associated with a boom/stick retraction; a left-hand movement is associated with swinging the excavator left; a right-hand movement is associated with swinging the excavator right; a clockwise hand twist is associated with a stick/boom extension; and a counter clockwise hand twist is associated with a stick/boom retraction.

A one-handed joystick for cranes allows an operator to make all necessary motions with a single hand and arm for manipulating various components of a crane. The one-handed joystick includes a rotatable cylinder bar, a rotatable ring, an industrial joystick base, a rocker switch and at least two push button switches. Motions of the rotatable cylinder bar, the rotatable ring, the industrial base and the rocker switch are used to raise and lower the auxiliary hoist; raise and lower the telescopic boom for luffing a hoist; raise and lower the main hoist; slew the boom base in a clockwise or counterclockwise direction; and extend or retract the telescoping boom. The speed of main and auxiliary hosts may be changed with the two push button switches. A Deadman's switch may be installed on a back side of the rotatable cylinder bar.

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.

A synchronous joystick sensor is provided, the synchronous joystick sensor includes a joystick, a joystick arm assembly, a swing detection assembly, a reset assembly. The joystick arm assembly is sleeved on the joystick, the arm assembly is driven by the joystick to swing in a first direction and a second direction perpendicular to the first direction. The swing detection assembly is configured to swing detection assembly, and configured to measure the swing amount in the first direction and the second direction through a magnetic detecting element, and convert the swing amount into a first electronic signal and a second electronic signal; a reset assembly configured to make the joystick being in a vertical reset state when there is no external force.

The invention relates to a manually operable control device for operating at least one actuator of a vehicle, comprising a manually operable control lever element which can be displaced from a default position by means of a rotation about a first axis and/or about a second axis, wherein a degree and/or a direction of a corresponding displacement of the control lever element can be detected by means of a sensor device, further comprising at least a first actuator device with a first drive unit and a first output unit, wherein, by means of the first actuator device, the first axis can be acted upon with a first torque, a second actuator device with a second drive unit and a second output unit, wherein, by means of the second actuator device, the second axis can be acted upon with a second torque, wherein the first output unit is rotatably mounted about the first axis and the second output unit rotatably mounted about the second axis.

A mechanical controller provides four-axis control of a vehicle's position and movement. For example, the controller provides control of a vehicle's operations through a lateral axis, longitudinal axis, directional axis, and a grip axis (e.g., operating a thumbwheel of the mechanical controller that provides additional control inputs to the vehicle). The mechanical controller can provide independent force feel mechanisms in each of the lateral, longitudinal, and directional axes of movement. Additionally, the mechanical controller may provide a redundant force feel mechanism (e.g., for increased safety). For example, redundant springs and dampers may be incorporated in each axis's force feel mechanism. The mechanical controller may include a plunger and spring assembly to provide a force feel mechanism in the lateral and longitudinal axes. In addition to this spring force, surfaces of a contact region between the plunger and a plunger actuating plate may be shaped to produce force feel characteristics.

In the hydraulic excavator, the control unit outputs the drive signals, which gives the motion corresponding to the motion of the hydraulic cylinder, the revolving motor of the revolving unit and the traveling device to the work implement operating lever, the right work implement operating lever and the traveling lever, to the drive section. The control section outputs the control signals based on the motion of the left work implement operating lever the right work implement operating lever or the traveling lever operated by the operator when the motion of the left work implement operating lever, the right work implement operating lever or the traveling lever operated by the operator is different from the motion corresponding to the motion of the hydraulic cylinder, the revolving motor of the revolving unit and the traveling device.

A work vehicle includes an operating lever configured to operate a work implement, an actuator configured to move the operating lever, and a control section configured to control the actuator to move the operating lever to a retreat position outside an operation range of the operating lever.

A joystick includes a casing, a stick body, an identification mark and an optical sensor. The casing has a hole. The stick body is movably disposed on the casing. The stick body has a first section and a second section. The first section penetrates through the hole to protrude from the casing, and the second section is inside the casing. The identification mark is disposed on the second section of the stick body. The identification includes a first line group and a second line group crossed to each other. The first line group and the second line group respectively has a plurality of lines with different widths and arranged adjacent to each other. The optical sensor is disposed inside the casing and adapted to acquire an identification image containing the identification mark to determine a gesture of the stick body.
