Generally, a sterile adapter for use in robotic surgery may include a frame configured to be interposed between a tool driver and a surgical tool, a plate assembly coupled to the frame, and at least one rotatable coupler supported by the plate assembly and configured to communicate torque from an output drive of the tool driver to an input drive of the surgical tool.

A robot can be an indoor cleaning robot. The robot can include a main body, mobility module, robotic arm, different cleaning tools, tool change module, and door opening module. The main body can have an outer housing containing internal components that facilitate autonomous indoor cleaning. The mobility module can move the robot autonomously across floors. The robotic arm can have a fixed end, movable end, and multiple movable arm segments therebetween. Each cleaning tool can be mounted along an outer robot surface and can be removed and manipulated by the robotic arm to perform a cleaning function. The tool change module can facilitate securely coupling and uncoupling the robotic arm to each different cleaning tool. The door opening module can pull and hold open a spring-loaded door while the mobility module moves the robot through the open door.

A robot comprises a mobile base, a robotic arm operatively coupled to the mobile base, and at least one interface configured to enable selective coupling to at least one accessory. The at least one interface comprises an electrical interface configured to transmit power and/or data between the robot and the at least one accessory, and a mechanical interface configured to enable physical coupling between the robot and the at least one accessory.
