A mobile robot includes a movable platform including wheels, and a manipulator having a base supported by the movable platform and an arm attached to the base, wherein a base attachment surface to which the base is attached is inclined relative to a movement surface on which the movable platform is to move.

An arm joint for a manipulator having a motor with a transmission, comprising a gear wheel that can rotate about a transmission axis of rotation, wherein the gear wheel is rotatably mounted in a housing of the arm joint and has an adapter on at least one of its end sides, and wherein the adapter has an opening that is central relative to the transmission axis of rotation on the side facing away from the end side of the gear wheel The central opening has an internal thread for the purpose of a simple construction, easy assembly and a great number of variation possibilities in terms of construction and application.

A structure of a robot includes: a first member having a hollow portion in the vicinity of a horizontal axis; a second member rotatably supported on a side surface of the first member and having a hollow portion in the vicinity of the horizontal axis; a drive motor producing power for rotating the second member; and a speed reducer reducing the rotation speed of the drive motor and transmitting the rotation to the second member. The speed reducer includes: an output hypoid gear formed of a ring gear disposed coaxially with the horizontal axis and fixed to the first member; an input hypoid gear engaged with the output hypoid gear; and a transmission mechanism transmitting rotation from the drive motor to the input hypoid gear while reducing the speed. The drive motor, the input hypoid gear, and the transmission mechanism are supported in the second member in an accommodated state.

A tunable actuator joint module of a robotic assembly comprises an output member and an input member, where the output member is rotatable about an axis of rotation. A primary actuator (e.g., a motor) is operable to apply a torque to rotate the output member about the axis of rotation. A quasi-passive elastic actuator (e.g., rotary or linear pneumatic actuator) comprising an elastic component is tunable to a joint stiffness value and is operable to selectively release stored energy to apply an augmented torque to assist rotation of the output member and to minimize power consumption of the primary actuator. The tunable actuator joint module comprises a control system having a valve assembly controllably operable to switch the quasi-passive elastic actuator between an elastic state and an inelastic state during respective portions of movement of the robotic assembly (e.g., a hip or knee joint of an exoskeleton). Associated systems and methods are provided.
