This paper's most distinctive feature lies in its proposed Transformer Transformer model, which can directly participate in the robot's body design. Only by inputting a segment of conditional trajectory into the model can one generate a complete robot structure suitable for completing these actions, encompassing links, joints, motors, and inertial properties.
