In various embodiments, a zero-turn radius robotic base may comprise a substantially rectangular (e.g., rectangular) base portion that comprises a plurality of wheels. In various embodiments, the plurality of wheels are configured to support the robotic base adjacent a support surface (e.g., the ground, a suitable flooring surface within a building, etc.). In some embodiments, the robotic base comprises a first and second driving wheel and a plurality of stability wheels. In some embodiments, an axis of rotation of the first and the second driving wheel are collinear. In various embodiments, the plurality of stability wheels are spaces apart from the axis of rotation of the first and second driving wheels to provide stability to the robotic base.

A purpose is to improve storability of a plurality of connection pieces coupled bendably. A robot arm mechanism includes a revolute joint and a linear extension and retraction joint. The linear extension and retraction joint includes a plurality of first connection pieces coupled bendably and provided with a hollow square cross section and a plurality of second connection pieces coupled bendably and each shaped like a flat plate. The second connection pieces are overlapped on the first connection pieces in upper part of the first connection pieces, thereby forming a columnar body by constraining bending. The columnar body is released when the first connection pieces and the second connection pieces are separated from each other. An ejection section forms the columnar body by joining the first connection pieces to the second connection pieces and supports the columnar body. The plurality of first connection pieces are coupled at an upper part and a lower part of each piece to be folded in a zigzag pattern and stored in a base with top faces of adjacent first connection pieces folded on top of each other and bottom faces of adjacent first connection pieces folded on top of each other alternately.

A refuse vehicle includes a chassis, tractive elements, a lift apparatus, and a reach assembly. The tractive elements couple with the chassis and support the refuse vehicle. The lift apparatus includes a track and a grabber assembly. The track includes a straight portion and a curved portion. The grabber assembly releasably grasps a refuse container and ascends or descends the track to lift and empty refuse into a body of the refuse vehicle. The reach assembly includes an outer member, a first extendable member, and a second extendable member. The first extendable member is received within an inner volume of the outer member and translates relative to the outer member. The second extendable member is received within an inner volume of the first extendable member and translates relative to the first extendable member. The lift apparatus is fixedly coupled at an outer end of the second extendable member.

A robotic arm control system including a robotic arm configured to deploy one or more tools in an operating space, one or more sensors, and a control system operably configured to: scan the operating space with the one or more sensors, identify a surface of the operating space based at least in part upon information sensed by the one or more sensors, establish a virtual barrier offset from the surface, and limit movement of the robotic arm based at least in part upon the virtual barrier.

A rigidity of a robot arm mechanism including a linear extension and retraction joint is enhanced. In a robot arm mechanism including the linear extension and retraction joint, the linear extension and retraction joint includes an arm section and an ejection section, the arm section includes a first connection piece string including a plurality of first connection pieces and a second connection piece string including a plurality of second connection pieces, and the second connection piece string is joined to the first connection piece string to thereby constitute a columnar body having a certain rigidity. The ejection section includes lower rollers and upper rollers for joining the first and second connection piece strings and supporting the columnar body. The lower rollers and the upper rollers are disposed with the columnar body sandwiched between the lower rollers and the upper rollers.

An electrodynamic apparatus includes a first arm extending in a first direction, a second arm supported by the first arm, and a first linear actuator that is provided in the first arm or the second arm and moves the second arm along the first direction with respect to the first arm. The first arm includes a first power transmission antenna. The second arm includes a first power reception antenna. The first power transmission antenna supplies electric power to the first power reception antenna wirelessly. The first power reception antenna supplies the supplied electric power to a load electrically connected to the first power reception antenna.

Some embodiments of the invention relate to a mechanism for actuating a shaft having two degrees of freedom, comprising: a first actuator configured to rotate the shaft around the shaft axis, and a second actuator configured to bend the shaft using one or more elongated elements attached to the shaft, wherein actuation of the first actuator indirectly manipulates the elongated elements controlled by the second actuator, thereby affecting operation of the second actuator. Some embodiments relate to motorized actuation of a system comprising at least one surgical arm.

A robot arm includes a second coupling rod fixedly coupled to a second intermediate base at an end of the second coupling rod located closer to the second intermediate base and coupled to a tip base via a second joint at an end of the second coupling rod located closer to the tip base so as to enable the second coupling rod to turn with respect to the tip base, and the first intermediate base and the second intermediate base are coupled together via an intermediate joint so as to be able to turn. The robot arm also includes a turning actuator that turns the second intermediate base with respect to the first intermediate base.
