An operation system includes an operation device and an information terminal connected to the operation device. The operation device has an operation section including a plurality of operating elements. The information terminal includes an operation registration section configured to register an operation involving use of at least one of the plurality of operating elements to a target operating element constituted by at least one of the plurality of operating elements, an operation determination section configured to determine whether or not the target operating element is operated, and an information generation section configured to generate, when the target operating element is determined to be operated, operation information corresponding to the operation registered to the target operating element by the operation registration section. Either the operation device or the information terminal includes an information transmission section configured to transmit the operation information generated by the information generation section.

There is provided a drive power transmitting mechanism that can transmit drive power losslessly and can be used in environments where silence is required. The drive power transmitting mechanism includes a rotor having a first outer circumferential surface and rotatable about a first rotational axis, a rotor having a second outer circumferential surface pressed against the first outer circumferential surface and rotatable about a second rotational axis due to a frictional force produced between the second outer circumferential surface and the first outer circumferential surface, a gear rotatable in unison with the rotor about the first rotational axis, and a gear rotatable in unison with the rotor about the second rotational axis, in which the gear and the gear are brought into mesh with each other when the second outer circumferential surface slips against the first outer circumferential surface.

A rotation device includes a two-axis rotation mechanism including a first bevel gear, a second bevel gear disposed at a position where the second bevel gear coaxially faces the first bevel gear in an axial direction, a third bevel gear that meshes with the first bevel gear and the second bevel gear, a first motor for supplying rotational force to the first bevel gear, and a second motor for supplying rotational force to the second bevel gear; a one-axis rotation mechanism including a drive shaft and a third motor for supplying rotational force to the drive shaft; and an attachment member that attaches the two-axis rotation mechanism to the one-axis rotation mechanism such that a rotational axis of the drive shaft passes a point of intersection where a rotational axis of the first bevel gear and the second gear and that of the third bevel gear intersect with each other.

A floor reaction force to a foot of a legged mobile robot is detected with a suitable degree of accuracy, by use of a strain sensor having comparatively low sensitivity. The foot includes an upper frame connected to a movable leg, a lower frame which is disposed under the upper frame and contacts with a walking surface, a strain generating member which is connected to the upper frame and the lower frame at different positions from each other in top plan view and undergoes bending deformation according to a change in distance or inclination between the instep member and the sole member, and a plurality of strain sensors disposed at positions different from each other on the strain generating member.

A configuration that exerts floor reaction force directly to a force sensor in a foot of a legged mobile robot requires a sensor having a large withstand load. A foot () includes an upper frame () that is connected to a movable leg and receives the load of a robot, a lower frame () that is deployed under the upper frame () and contacts with a walking surface, a high rigidity spring () attached the lower frame () and elastically supporting the upper frame () against the load, and a plurality of sensor mechanisms that detect floor reaction force at positions different from each other on the lower frame (). Each of the sensor mechanisms includes a force sensor () attached to one of the upper frame () and the lower frame () and a sensor spring () that is an elastic body having rigidity lower than that of the high rigidity spring () and has a supporting point deployed on the other one of the upper frame () and the lower frame () so as to exert pressing force to the force sensor () according to a change of the distance between the upper frame () and the lower frame ().
