The transmission path includes at least one wireless transmission sub-path for wireless transmission of data signals, and at least one wire-guided transmission sub-path for wire-guided transmission of data signals. The rotation-compatible data transmission device includes at least one first wireless transmission unit and at least one second wireless transmission unit, interconnected via the transmission path and arranged to wirelessly transmit and receive data signals along the wireless transmission sub-path. An industrial robot can have a plurality of such arm modules.

An instrument holder generally includes a carriage rotatable with respect to a carriage support, a light pipe extending axially through the carriage, and an electrical conductor extending through the carriage radially outward of the light pipe. The light pipe can transmit light energy and the electrical conductor can transmit electricity between a proximal end portion and a distal end portion of the carriage to a medical instrument. The rotatable carriage may include a sterile adapter assembly positioned at the proximal and/or distal end portions of the rotatable carriage. The sterile adapter assembly may include a roll disk rotatable with respect to the outer frame, an inner disk rotatable with respect to the roll disk, and a light pipe to transmit light energy through the roll disk. The inner disk can transfer movement of an actuator between the rotatable carriage and the instrument.

One or more of a thermal management, a power distribution, or a communication is effected through the second link.

A unique electro optical robot design is disclosed, which includes hollow optical members creating a beam delivery system. The laser beam is coupled to an input aperture on the robotic arm and travels through hollow arms which rotate in respect to each other. Said input laser beam is delivered to a specific point in space within the reach of the arms with great accuracy. The arms themselves are designed to minimize angular deviations by using elongated periscopes or retroreflectors. This design is characterized by the ability to deliver a near collimated laser beam with great accuracy and capable of fusing together several laser beams of different wavelengths. Moreover, since the laser beam travels in a collimated mode, a lightweight focuser is the only necessary optical element, thus significantly reducing the load on the end tip of said robotic arms. The purpose of this invention is to offer a multi wavelengths accurate beam delivery system, acting in a robotic mode.
