MULTI-CABLE ACTUATION FOR ENERGY-EFFICIENT TENSEGRITY ROBOTS

A tensegrity robot includes multiple tensile members connected to multiple structural members to form a spatially defined structure. Each structural member is connected to one or more other structural members by tensile members therebetween. The robot further includes multiple actuators operatively connected to the tensile members and the structural members, and multiple controllers configured to communicate with each of the actuators. The controllers direct control of at least one of tension or length of the tensile members by the actuators to cause a change in at least one of the size, shape or center of gravity of the spatially defined structure to effect robotic actions. At least two tensile members are connected to an actuator such that at least one of tension or length in both of the tensile members are changed in coordination by the actuator.

A robot includes a main body, a handlebar disposed on the main body and grippable by a user, a detection unit that detects a load applied to the handlebar, a moving device including a rotating body and moving the robot by controlling the rotation of the rotating body, and a switching unit that switches a support mode for supporting the user with walking. The support mode includes a first mode in which the robot autonomously moves to guide the user who is walking and a second mode in which the robot moves in accordance with a first load detected by the detection unit. When the robot moves in the first mode, the switching unit switches the support mode from the first mode to the second mode on the basis of the second load detected by the detection unit.
