A waist imitating device of robotic rat based on multiple-connecting-rod transmission comprises a pitch parallel connecting rod group (8) and a yaw parallel connecting rod group (2). The pitch parallel connecting rod group (8) and the yaw parallel connecting rod group (2) are respectively connected with a front joint and a back joint of a waist of a robotic rat. Under the drive of a first motor (4), crank connecting rods drive the yaw parallel connecting rod group (2) such that left-right yaw motion of the waist of the robotic rat relative to wheels and forelimbs can be achieved. Under the drive of a second motor (14), crank connecting rods drive the pitch parallel connecting rod group (8) such that upper-down pitch motion of the waist of the robotic rat relative to the wheels and the forelimbs can be achieved.

The invention relates to a joint arrangement having at least one driven axis, in particular for activating a movement of a component of a robot, wherein a first base element (15) receives a first rotary element (16), and the first rotary element (16) is rotatable about a first axis of rotation (14), the first rotary element (16) receives a second axis of rotation (18), separate from the first axis of rotation (14) and about which a second rotary element (22) is pivotably mounted on the first rotary element (16), the second rotary element (22) has a third axis of rotation (25) separate from the second axis of rotation (18) and about which a second base element (26) is rotatable with respect to the second rotary element (22), the second axis of rotation (18) has an axial offset (19) in relation to the first axis of rotation (14), and the second axis of rotation (18) is inclined with respect to the first axis of rotation (14), and the first and second axes of rotation (14, 18) have a point of intersection (29) which lies outside the joint arrangement (11).

Provided are an SEA, a method of controlling the SEA and a system using the same. The SEA includes a motor-side rotation unit coupled to a driving motor and rotated by rotatory power of the driving motor, a load-side rotation unit coupled to the motor-side rotation unit to transfer the rotatory power of the driving motor to a load, and at least one pair of elastic members provided in spaces between the motor-side rotation unit and the load-side rotation unit. A frame having accommodation spaces to which the pair of elastic members is fixed is formed in any one of the motor-side rotation unit and the load-side rotation unit.

A robot that includes a base that is provided with a flat installation surface member that is disposed on an installation target surface and a columnar member that extends upward from the installation surface member; and a first arm, one end of which is supported so as to be rotatable about a first horizontal axis located above the columnar member of the base and that has a motion range below the first horizontal axis. The columnar member has a length that is equal to or longer than the length of the first arm and has a uniform transverse sectional area that is the same as the first arm.

A housing of a joint of a collaborative robot, where at least part of the material of the housing is configured to include a plurality of lattice structure units. Since the at least part of the material of the housing is configured to include the plurality of lattice structure units, the weight of the joint may be reduced with respect to a completely solid housing. Further disclosed is the joint of the collaborative robot.

A reusable mechanism is disclosed for coupling two robotic appendages, such that an unintended force acting against a side of one of the appendages may decouple the appendages. The mechanism includes a revolved male dovetail mated to a revolved female dovetail. The mechanism may further include a channel within the male dovetail and a detent that inhibits rotation of the male dovetail in relation to the female dovetail.
