摘要:
A work apparatus includes a parallel link mechanism, a position control actuator, a linear motion mechanism, and a rotating mechanism. The parallel link mechanism includes three or more link mechanisms that couple a distal end side link hub to a proximal end side link hub such that a position of the distal end side link hub can be changed relative to the proximal end side link hub. The position control actuator operates the parallel link mechanism. The linear motion mechanism moves a working body in an axial direction orthogonal to a central axis of the proximal end side link hub. The rotating mechanism is mounted on the distal end side link hub and rotates a work object about a rotation center axis parallel to a movement direction of the linear motion mechanism when the central axis and a central axis are on the same line.

Embodiments of the present invention provide methods and systems to analyze wearable technology. A robot with snake assembly works in conjunction with a server in order to simulate the locomotive actions of appendages and to concomitantly determine the response of wearable technology devices, which are attached to the snake robot assembly, to the simulated locomotive actions.

The disclosure concerns a robot of the type including a base element and a mobile element coupled to the base element through an element for triggering movement. The movement-triggering element includes first and second subassemblies. The first assembly is designed to move the mobile element along a substantially vertical direction. The second subassembly connects the first subassembly to the mobile element and includes at least three actuators capable of acting in parallel to move the mobile element in a substantially horizontal plane independently of the first subassembly.

Then an end effecter is used to operate a heavy object, a large bending moment may act on arms of a manipulator to bend them. Consequently, an operating section cannot precisely control positions. Thus, according to the present invention, three arms 14 are attached to a base section 11, each of the arms 14 being composed of a first link section 15 having one end connected to a rotating shaft 12 on the base section 11 and a second link section 17 connected to the first link section 15 via another rotating shaft 16. These arms 14 support an operating section 19. The second link section 17 is connected to the rotating shaft 16 and to the operating section 19 using universal joints 18a and 18b. Direct acting driving means 13 is composed of a driving shaft 13a and a driving source that advances and retreats the driving shaft 13a. The driving shaft 13a is driven to advance and retreat to move the operating section 19 to a desired position. In this case, the operating section 19 is always kept parallel with a particular plane. Loads on the operating section 19 act in the axial directions of the driving shafts 13a. This prevents the driving shafts 13a from being bent or deformed, thus enabling precise positional control.
