Robotic arm with quick-connect clamping system and docking cradle
A system comprising an articulated robot arm including assembly of links interconnected with motorized joint units at joints between the links for movements of the links relative to one another, one of the links being a base link. A docking cradle is adapted to be connected to a structure and configured for being releasably connected and for supporting the articulated robot arm. A coupling configuration is between the base link and the docking cradle for powering contact to be made. A clamping system includes one or more clamp members and a clamp lever for locking the base link to the docking cradle at the coupling configuration.

a clamping system including two clamp members and a clamp lever for locking the base link to the docking cradle at the coupling configuration;
wherein the clamp members are each pivotally connected to a wall to define a female cavity therewith, the clamp lever pivotally connected to both of the two clamp members to tighten the female cavity.
2. The system according to claim 1 , wherein the clamp members are separated by a gap, and the clamp lever includes a cam-shaped end to open and close the gap.
3. The system according to claim 2 , further comprising a pin and pin receptacle set between the clamp lever and the docking cradle for vertical alignment of the docking cradle with the base link.
4. The system according to claim 1 , wherein the coupling configuration includes a male block on the docking cradle for being coupled into the female cavity.
5. The system according to claim 4 , wherein the base link has a vertical wall defining a portion of the cavity.
6. The system according to claim 5 , wherein the vertical wall is received between the male block and another male block of the docking cradle.
7. The system according to claim 1 , wherein the clamp lever and one of the clamp member are fitted into the other clamp member when tightening the female cavity.
8. The system according to claim 1 , wherein the female cavity is in the base link, and the coupling configuration includes a male block on the docking cradle for being coupled into the cavity.
9. The system according to claim 8 , further comprising wedge surface sets in the male block and the clamping system for vertical alignment of the docking cradle with the base link.
10. The system according to claim 1 , further comprising a lockable translational joint between one of the clamp member and the clamp lever to adjust the tightening.
11. The system according to claim 1 , further comprising a plurality of the docking cradle for one of the articulated robot arm, the articulated robot arm being releasably connected between the plurality of the docking cradle.
12. An assembly comprising:
a docking cradle adapted to be connected to a structure;
