An operation device according to the present invention includes: a rotation operation unit that is rotatable about a rotation axis and is installed so that an operation site formed on a rotation surface is exposed outside through an opening formed in an operation panel; and a support unit that covers at least part of a separated site of the rotation operation unit located away from the operation site along a rotation axis direction and has a sliding site coming into contact with part of the separated site and slidably supporting rotation of the rotation operation unit. Then, the support unit is configured to form a space part retaining grease applied to the rotation operation unit between the support unit and the separated site located on a side opposite to the operation site of the rotation operation unit with reference to the sliding site.

An airplane rudder and brake pedal assembly includes a rudder arm assembly having one rudder arm with first upper and lower arm portions, and another rudder arm with second upper and lower arm portions. The rudder arm assembly is assembled to a beam at an intersection of the first upper and lower arm portions, and an intersection of the second upper and lower arm portions. The first and second rudder arms are configured to rotate about the beam at the intersection. The rotation of the first and second rudder arms is configured to adjust control surfaces that control a yaw axis of the airplane. A brake pedal is attached to the first and second lower arm portions. Rotation of the brake pedal brakes the airplane. A rotary sensor is assembled to the brake pedal and the lower arm portion, and configured to determine an extent of the brake pedal rotation.

Certain aspects relate to systems and techniques for an input device for controlling a robotic surgical tool. The input device can include a first pair of opposing links and a second pair of opposing links. The first pair of opposing links and second pair of opposing links can be arranged radially symmetrically. The input device can be configured to control operation of the robotic surgical tool.

A throttle operating device includes a fixing member, a throttle lever, and a detection sensor. A drive source of the transport is configured to be controlled based on the rotational operation angle of the throttle lever detected by the detection sensor. The throttle lever is configured to be rotated in a forward direction and a reverse direction. When the throttle lever is rotated in the forward direction, the drive source of the transport can be controlled. When the throttle lever is rotated in the reverse direction, a predetermined device mounted on the transport can be operated or an operation of the predetermined device can be stopped.

An operator control device has an actuation unit on a console unit. The actuation unit movable between an idle position and one or more actuation positions. The actuation unit is fixable in the idle position by a retaining device. In order to leave the idle position, it is necessary to overcome a retaining force provided by the retaining device. The retaining device has a coupling device with a coupling element that is magnetically couplable to the actuation unit and to the console unit in order to magnetically fix the actuation unit in at least the idle position.

An operating device includes a control knob, an actuator, a first switch, a second switch, and a holder. An accommodating space of the holder is defined by a first accommodating portion extending in a first direction. A first arm is accommodated in a first accommodating portion. A second arm is accommodated in a second accommodating portion. The first arm or the first accommodating portion includes an allowance portion that allows for tilting of the actuator in the second direction, without interference between the first arm and the first accommodating portion. The second arm or the second accommodating portion includes an allowance portion that allows for tilting of the actuator in the first direction, without interference between the second arm and the second accommodating portion.

A cruise control system for work machines. The system comprises one or more levers for controlling the velocity of the work machine and one or more magnet assemblies. The magnet assemblies comprise means of overcoming the neutral bias of a control lever so that the velocity of the work machine may be maintained without manual input from the operator. The magnets may act directly upon a control lever or a surface adjacent a control lever. Additional controls may be employed to set a maximum cruising speed for the work machine when cruise control is engaged.
