Abstract
An apparatus for determining oil leakage of a gearbox and an associated robot. The apparatus includes a base arranged between the gearbox and a motor coupled to the gearbox. The base can be made of a oil-absorbing material such that a volume of the base changes when the base contacts oil. The apparatus also includes a signal generator coupled to the base and configured to cause an electrical signal or a change in a physical property of the signal generator in response to a change in the volume of the base. The apparatus also includes a controller coupled to the signal generator and configured to detect the electrical signal or the change in the physical property and to determine the oil leakage in response to a detection of the electrical signal or the change in the physical property.
