Robotic massage end effector
A massage robot arm end effector includes a mounting interface that is attachable to a robot arm. It further includes a surface distal from the mounting interface having a variable curvature that comprises a plurality of interaction regions. The surface is paired with a garment worn by a subject.
1 . A massage robot arm end effector, comprising:
a mounting interface of the massage robot arm end effector that is attachable to a robot arm, wherein attaching the massage robot arm end effector to the robot arm comprises inserting of the mounting interface into a slot of a receiving portion of the robot arm, wherein the receiving portion of the robot arm comprises a screw, wherein the mounting interface of the massage robot arm end effector comprises a threaded insert, and wherein securing of the massage robot arm end effector to the robot arm is facilitated at least in part by turning the screw of the receiving portion of the robot arm about an axis along which the mounting interface of the massage robot arm end effector slots into the receiving portion of the robot arm, wherein the axis about which the screw is turned is perpendicular to an axis passing through the receiving portion of the robot arm and the mounting interface of the massage robot arm end effector;
a surface distal from the mounting interface having a variable curvature that comprises a plurality of interaction regions that have different shapes;
a shell with varying material thickness for different interaction regions;
an internal skeleton that supports the shell and over which the shell is molded, wherein the internal skeleton comprises a rigid structure that is shaped with local concavities or convexities to accommodate the varying material thickness for the different interaction regions; and
one or more heating elements placed on the internal skeleton and between the shell and the internal skeleton.
