An adapter has a proximal end and a distal end, with the proximal end connected to the flexible ball base, and an end-effector connected to the distal end. | 02-11-2016 |
20160067868 | MODULAR END EFFECTOR - A system and method is disclosed of configuring a robotic end effector to prevent two or more axes of joints of a robotic arm from being in alignment. A connecting part is attached between a robotic arm and a tool in a pre-determined configuration chosen to prevent the two or more axes of joints of the robotic arm from being in alignment for a selected process involving the tool. Reconfigurable end plates may be disposed between the connecting part and the robotic arm, and between the connecting part and the tool to put the connecting part into the pre-determined configuration which prevents the two or more axes of the joints of the robotic arm from being in alignment for the selected process involving the tool. | 03-10-2016 |
20160101526 | ROBOT AND ROBOT JOINT MECHANISM - A robot according to an aspect of an embodiment includes a driving body, a driven body that is rotatably coupled to the driving body, a driving device that drives the driven body and is provided on the driven body, and an encoder that is attached to a final output shaft of the driving device. | 04-14-2016 |
20160114491 | WRIST STRUCTURE FOR AN ARTICULATED ROBOTIC ARM - A wrist structure for an articulated robotic arm includes: a wrist body, a rotary member, a signal processing circuit board, a connector, a control unit and a drive unit. The wrist body includes a front end portion, a rear end portion, a receiving portion, and a wiring hole formed in the rear end portion. The rotary member is rotatably connected to the front end portion. The signal processing circuit board is removably disposed at the rear end portion, located inside the receiving portion and includes a gap aligned with the wiring hole. The connector is disposed in the wrist body and signal connected to the signal processing circuit board. The control unit is disposed inside the receiving portion and signal connected to the signal processing circuit board. The drive unit is disposed in the receiving portion to control the rotary member to swing with respect to the wrist body. | 04-28-2016 |

20160158943 | ROBOT WITH WRIST AND END EFFECTOR DIFFERENT MATERIALS - An apparatus including a robot arm comprising a wrist, and an end effector. The wrist includes a frame member. The frame member includes a first material having a first coefficient of thermal expansion. The end effector is connected to the wrist at a connection. The end effector is configured to support a substrate thereon. The end effector includes a first member and a second member. At least one of the first and second members has a different second material with a different second coefficient of thermal expansion. The connection includes the first and second members being stationarily attached to each other with a portion of the frame member sandwiched therebetween. The connection is configured to substantially prevent the different respective coefficients of thermal expansion to deflect the end effector relative to the wrist when the end effector and wrist are heated and/or cooled. | 06-09-2016 |
