A mechanism 21 for converting rotating motion to rotating and reciprocating motion and/or vice versa. The mechanism has a housing or support 22, a first member 23 rotatable about a first axis and reciprocable along the first axis, and a second member 2 rotatable about a second axis spaced from the first axis. Rotation of the first member 23 or the second member 25 causes rotation of the other member. A guide 29a, 29b is configured to contact a cam surface 27a, 27b. The cam surface or the guide is provided on the first member 23. The cam and guide are configured to cause the first member 23 to rotate upon movement of the first member along the first axis, or to move along the first axis upon rotation of the first member 23.

A drive link includes a first bearing housing, a second bearing housing, and a central portion coupled between the first bearing housing and the second bearing housing. The central portion includes a central radial bearing configured such that the central portion twists in response to cocking of the first bearing housing relative to the second bearing housing.

A system that makes up at least a portion of a utilitarian article and having: a first body; a second body; and a first linkage assembly acting between the first and second bodies and configured to allow the first and second bodies to be relatively positioned to thereby reconfigure the article into which the system is incorporated. The first linkage assembly has first and second linkage parts. The first linkage assembly is configured so that: a) the first linkage part is movable relative to the first body around a first axis; b) the second linkage part is movable relative to the first linkage part around a second axis; and c) the second linkage part is movable relative to the second body around a third axis. At least one of the first, second, and third axes is non-parallel to the other two of the first, second, and third axes.

The present disclosure relates to a system that uses linear actuators to generate a torque on a shaft. In an example implementation, a system may include a shaft and an attached cam. The cam includes an involute portion. The system also includes a first linear actuator and a second linear actuator configured to move along a first axis and a second axis, respectively. The linear actuators are configured to detachably couple to the cam based on at least a reference angle of the shaft. That is, as the shaft rotates about its rotational axis at the reference angle, the first and the second linear actuators may couple to, and decouple from, various portions of the cam. As the linear actuators couple to, and decouple from, the various portions of the cam, different rotational torques and/or different ranges of such torques may be imparted onto the shaft.

Disclosed are device and method for driving a shift lever. The device may include a control unit that sets a travel distance of the shift lever when the shift lever is manipulated to a predetermined shift stage to be different than a reference travel distance of the shift lever, which is a travel distance of the shift lever when the shift lever is manipulated to shift stages other than the predetermined shift stage. The device may further include a driving unit which restricts a travel of the shift lever or moves the shift lever depending on a setting of the control unit.

The present invention relates to a bar member, an assembled component comprising the bar member, and a robot comprising the bar member. The bar member has a width and a thickness, wherein the width of the bar member is four times of the thickness thereof, and connecting holes running through the bar member along a thickness direction of the bar member are provided on the bar member. By using the bar member to form an assembled component, the need of conveniently realizing the most variety of movement mechanisms may be satisfied, and the most variety of movement functions may be achieved.

Embodiments of this disclosure are directed to devices that allow for adjusting of device parameters in a manner that does not involve power dissipation in an essential way. Thus, power demands when such devices are used in applications can be insignificant. This applies to both springs and inerters, which constitute basic lossless building blocks of mechanical device systems, and are analogues of inductors and capacitors in electrical circuits. Embodiments of this disclosure are also directed to a lossless adjustable 2-port transformer, and realization of mechanical translational and rotary transformers are set forth in the following. Embodiments of this disclosure allow for reduction of power demands in adjusting device parameters.
