• Design and calculation of transmissions (e.g., harmonic drives, planetary gears, cycloidal gears)
• Dimensioning of motors, bearings, shafts, and couplings
• Evaluation of feedback efficiency, stiffness, play, and wear
• Close cooperation with control engineering, electronics, and system architecture
• Support in prototype construction, testing, and commissioning
• Analysis of failure mechanisms and derivation of improvement measures
• Technical coordination with suppliers and evaluation of purchased components

• Degree in mechanical engineering, mechatronics, or comparable field
• Several years of experience in the design of actuators and/or gearboxes
• Very good knowledge of:
  • Gearbox technology
  • Drive design
  • Machine elements
• Understanding of dynamics, cont rollability, and system integration
• Experience with CAD systems (CREO, Solid Works, NX) and mechanical design
• Ability to translate mechanical requirements into system characteristics
• Good knowledge of German or English

• Experience in robotics or humanoid systems
• Knowledge of motor control and power electronics
• Experience with torque control or direct drive concepts
• Knowledge of thermal design of drive systems
• Experience with endurance and life cycle testing
