1. A remote control device, comprising:
a first arm supported by a base part;
a second arm connected to a tip-end part of the first arm;
two rotary bodies disposed side by side at a tip-end part of the second arm;
a link structure in which link members are fixed to the two rotary bodies, respectively; and
a user interface attached to the link structure,
wherein the two rotary bodies are independently and rotatably supported by respective coaxial drive shafts disposed horizontally,
wherein the user interface is pivotable with respect to the second arm on each of mutually-perpendicular three axes passing through a center point of the link structure,
wherein the link structure is disposed at a lateral side of the rotary bodies so that the center point is located on an axis of the two drive shafts,
wherein the link structure comprises:
a first link member connected to a first rotary body of the rotary bodies a base of the first link member directly connecting to an off-center portion of a first outward facing side surface of the first rotary body spaced apart from and not connected to the respective coaxial drive shaft thereof;
a second link member connected to a second rotary body of the rotary bodies, a base of the second link member directly connecting to an off-center portion of a second outward facing side surface of the second rotary body opposite the first outward facing side surface. and spaced apart from and not connected to the respective coaxial drive shaft thereof;
a first bracket that is connected to the first link member, is located on an axis of a rotation shaft passing through the center point, and rotates about the rotation shaft; and
a second bracket that is connected to the second link member, is located on the axis of the rotation shaft, and rotates about the rotation shaft, and wherein the user interface comprises:
an offset arm that is connected to the second bracket, on the axis of the rotation shaft, on an opposite side of the link structure from the center point, rotates about the rotation shaft, and extends in a direction which is oriented away from the axis of the rotation shaft and intersects with the axis of the rotation shaft; and
a grip extending from the offset arm in a direction which is oriented away from the axis of the rotation shaft.
