1. A sealing assembly comprising:
a housing adapted to be arranged on and cover an end of a first component of a robot and comprising a circumferential coupling section;
a flange adapted to be arranged on and cover an end of a second component of the robot that is coaxially rotatable relative to the first component, so that at least the circumferential coupling section of the housing abuts and surrounds the flange coaxially; and
an elastic sealing ring comprising:
a coupling portion coupled to the circumferential coupling section; and
a sealing portion arranged between an inner circumferential surface of the circumferential coupling section of the housing and the flange with an interference fit, the sealing portion is of a shape to match shapes of the housing and the flange to enable a seamless transition from the housing to the flange.
