Abstract: A flexspline protective structure includes a first rotation member, a second rotation member and a plurality of fixing members. The second rotation member is sleeved on the first rotation member. The plurality of fixing members fix the first rotation member and the second rotation member together and are capable of breaking off in the event of jamming or other mischance to enable the second rotation member to rotate freely relative to the first rotation member. The disclosure presents a robot arm mechanism equipped with the flexspline protective structure.

Abstract: A compact and gearless driving mechanism with a reduced operational envelope includes a support frame and two driving assemblies. The support frame includes a top plate and a bottom plate. Each driving assembly includes a first linear driving module, a second linear driving module intersecting with the first, and a third linear driving module intersecting with the second. The first linear driving module drives the second linear driving module to move along the first linear driving module, the second linear driving module drives the third linear driving module to move along the second linear driving module. A driving direction of each third linear driving module is inclined relative to the driving directions of the first linear driving module and the second linear driving module.

Abstract: Compact robot with a reduced operational envelope includes a support frame, two robot arm assemblies, and two actuating mechanisms. The support frame includes a top plate and a bottom plate. Each robot arm assembly includes a first arm, a second arm intersecting with the first, and a third arm intersecting with the second. The first arm drives the second arm to move along the first arm, the second arm drives the third arm to move along the second arm. The actuating mechanisms are coupled to the two third arms. Each third arm drives an actuating mechanisms to move along the third arm. A moving direction of each actuating mechanism as driven by the third arm is inclined relative to the driving directions of the first arm and the second arm.

Abstract: A deceleration mechanism comprises a driving wheel, a driven wheel of a diameter exceeding that of the driving wheel, a transmission member coiling around the driving wheel and the driven wheel; and a tension assembly fixed to the driven wheel. The transmission member coils around the driving wheel, criss-crosses, and coils around the driven wheel. The tension assembly is arranged between the transmission member and the driven wheel and elastically resists the transmission member and the driven wheel.

Abstract: A conveying device includes a housing, a linear driving mechanism, a first sliding assembly, a second sliding assembly, and a carrying mechanism. The linear driving mechanism is assembled within the housing. The first sliding assembly is slidably assembled together with the second sliding assembly within the housing, and both sliding assemblies are driven by the linear driving mechanism to slide horizontally. The carrying mechanism is slidably sandwiched between the first sliding assembly and the second sliding assembly. The first sliding assembly and the second sliding assembly are driven by the linear driving mechanism to slide within the housing along either a same direction or along opposite directions. The carrying mechanism may slide linearly together with the first sliding assembly and the second sliding assembly, or slide upwards and downwards perpendicular to the linear sliding direction of the first sliding assembly and the second sliding assembly.

Abstract: A mobile platform with six degrees of freedom includes a static base plate, six branched chain, a dynamic moving plate and twelve fixing assembly. Each of the static base plate and the dynamic moving plate defines six spherical ball sockets. The dynamic moving plate is adjustably and movably mounted upon the static base plate. The six branched chains is adjustably assembled between the static base plate and the dynamic moving plate, enabling the dynamic moving plate to move relative to the static base plate along six degrees of freedom. Each branched chain comprises two ball heads rotatably engaged with one corresponding ball socket of the static base plate and one corresponding ball socket of the dynamic moving plate.

Abstract: A magnetic gear includes a gear base, magnetic members, rotating members, operating members, and a cover. Each magnetic member is a bar magnet. The magnetic members are rotatably positioned on the gear base, and a rotation axis of the magnetic member is substantially parallel to an axis of the magnetic gear. The rotating members are also received in the gear base. The cover is fixed to the gear base, and defines a plurality of through holes corresponding to the magnetic members. The gear base includes a connecting plate. Magnetic torque between two magnetic gears and also the transmission ratio of the corresponding magnetic gears can be both changed by rotating the operating members together with the magnetic members and the rotating members, and by having the rotating member resisting a different restricting surface of the connecting plate.

The first and the second kinematic chains are connected to the fixed platform and the movable platform respectively, and move on the same plane.

Abstract: A joint mechanism includes a first rotary unit and a second rotary unit. The first rotary unit includes a base and a first joining end. The first joining end defines a first chamfered rim. The second rotary unit includes a second joining end to join to the first joining end. The second joining end defines a second chamfered rim. The first chamfered rim and the second chamfered rim cooperatively form a slanted groove. The groove communicates with an outside of the first and second rotary units and has an opening facing the base.

The cable is fixed relative to the second member. A first through hole (128) is defined in the first member. The cable-protecting structure includes a bearing (161). The bearing includes an inside ring (163) and an outside ring (164) rotatable relative to each other. The bearing is received inside of the first through hole. The outside ring of the bearing is fixed to the first member. The cable is spaced from a ledge (1282) formed the first through hole and supported by the inside ring of the bearing.
