Abstract: The present invention relates to the technical field of spacesuit performance tests, and in particular to a robot for testing lower limb performance of a spacesuit, comprising a pressure maintaining box, an air circulation component, an air cooling unit, heat radiating hose components and two mechanical legs. The air cooling unit is connected with the pressure maintaining box; the air circulation component is arranged in the pressure maintaining box; the mechanical legs are installed on the pressure maintaining box, and the heat radiating hose components are arranged in the mechanical legs; air in the pressure maintaining box is cooled through the air cooling unit and delivered into the heat radiating hose components through the air circulation component; each mechanical leg comprises a thigh, a knee joint component, a shank, an ankle joint component and a foot; the thigh is connected with the shank through the knee joint component; the shank is connected with the foot through the ankle joint component; the knee joint component is provided with a knee joint driving component and a knee joint transmission component; and the ankle joint component is provided with an ankle joint driving component and an ankle joint transmission component. The present invention has high control precision of motion tracks and adjustable size, and is suitable for testing lower limbs of different spacesuits.
