Abstract: A robot R includes a pair of crawler devices 2 supported by a body 1. Each of the crawler devices 2 includes a crawler unit 3 supported by the body 1 such that the crawler unit 3 is rotatable about a first rotational axis L. The crawler unit 3 includes a support 10 extending along the first rotational axis L1 and a pair of crawler parts 20A, 20B mounted on the support 10. Each of the crawler device 2 includes a rolling driving member 46 connected to the support 10 of the crawler unit 3, a rolling motor 60 that rotationally drives the rolling driving member 46, a crawler drive shaft 41 extending along the first rotational axis L1 through a gap between the pair of crawler parts 20A, 20B, a crawler motor 50 that rotationally drives the crawler drive shaft 41 and a torque transmitting mechanism 42 that transmits rotary torque of the crawler drive shaft 41 to the pair of crawler parts 20A, 20B, The crawler motor 50, as well as the rolling motor 60, is disposed outside of the crawler unit 3.

Abstract: A traveling apparatus that can be moved in two directions includes a body 1, a pair of crawler units 5, crawler actuators 40 and rolling actuators 60. The crawler units 5 are supported by the body 1 such that the crawler units 5 are rotatable about a rotational axis L1. The traveling apparatus performs crawler moving in a direction of the rotational axis L1 by the crawler actuator 40 driving pairs of crawler structures 20A, 20B of the crawler units 5. The traveling apparatus performs moving by rolling in a direction orthogonal to the rotational axis L1 by the rolling actuator 60 making the crawler units 5 roll about the rotational axes L1. To prepare for the crawler moving, the crawler units 5 are made to roll to take a movable attitude based on attitude information of the crawler units 5 from rotary encoders 72.

Abstract: A crawler device 2 includes a crawler unit 5. The crawler unit 5 includes a first support 10 extending along a first rotational axis L1, a pair of crawler structures 20A, 20B mounted on the first support 10 and a pair of ground contacting structures 30A, 30B mounted on the first support 10. The pair of ground contacting structures 30A, 30B are arranged outside of the pair of crawler structures 20A, 20B in a direction in which the pair of crawler structures 20A, 20B are opposed to each other. The crawler unit 5 is supported by second supports 41, 42 such that the crawler unit 5 is rotatable about the first rotational axis L1. An outer periphery of the crawler unit 5 having a circular cylindrical configuration includes first zones Z1 occupied by the pair of crawler structures 20A, 20B and second zones Z2 occupied by the pair of ground contacting structures 30A, 30B alternately arranged in a circumferential direction.

Abstract: In the present invention, a crawler belt (10) is provided with: an endless belt main body (11); a plurality of tread lugs (12) formed at the outer periphery of the belt main body (11) with spaces therebetween in the peripheral direction; and a pair of disengagement prevention sections (13) that are formed along the peripheral direction of the belt main body (11) at the inner periphery of the belt main body (11) and are separated in the width direction of the belt main body (11). The disengagement prevention sections (13) are configured from a plurality of rib segments (13a) extending in the peripheral direction and disposed along the peripheral direction with spaces therebetween. Each rib segment (13a) is disposed at a position in the peripheral direction corresponding to a tread lug (12).
