A robot arm comprises a plurality of joints ( 10 ) which are connected to each other by connection elements ( 12 ). The connection elements ( 12 ) carry heat-generating components ( 14 ), particularly electronic components comprising thermally critical parts. For cooling these components, at least one connection element ( 12 ) comprises a heat-dissipating element made from a ceramic material. Preferably, the whole connection element ( 12 ) is made from a ceramic material. Due to their low thermal expansion coefficient and their good thermal conductivity, ceramic materials offer considerable advantages in comparison with support structures made of aluminum.
