Abstract: A radiation emission device is provided. The radiation emission device may include a cathode configured to emit an electron beam and an anode configured to rotate on a shaft. The anode may be situated to receive the electron beam from the cathode. The radiation emission device may further include a rotor configured to drive the anode to rotate. The rotor may be mechanically connected to the shaft. The radiation emission device may further include a sleeve configured to support the shaft via at least one bearing. The cathode, the anode, and the rotor may be enclosed in an enclosure that is connected to the sleeve. At least a portion of the sleeve may reside outside the enclosure.

Abstract: The present disclosure provides a master manipulator. The master manipulator may include an arm assembly including at least one arm joint mechanism and a wrist assembly movably connected with the arm assembly. The wrist assembly may allow an operator to perform a corresponding operation. The wrist assembly may include at least one wrist joint mechanism. The master manipulator may also include a support assembly configured to support at least one of the arm assembly and the wrist assembly.

Abstract: Embodiments of the present disclosure provide a robot and a master manipulator thereof. The master manipulator includes: an end control assembly; and an attitude adjustment assembly. The attitude adjustment assembly may include a first mechanism and a second mechanism, the first mechanism and the second mechanism are connected to the end control assembly, and the end control assembly controls the first mechanism and the second mechanism to move through the connection between the first mechanism and end control assembly and the connection between the second mechanism and the end control assembly.
