Leg Mechanics Engineer
Humanoid
Engineer humanoid locomotion – design robust leg systems, optimize dynamic stability, and propel RoboTUM’s walking innovation!
Responsibilities & Tasks
Design and optimize the mechanical structure of the humanoid robot’s legs, focusing on weight, durability, and dynamic performance.
Develop and integrate actuators, linkages, and joints to achieve efficient and natural walking motions.
Analyze and simulate forces, torques, and stresses acting on the leg components using FEA and other modeling tools.
Select materials and manufacturing processes (e.g., 3D printing, CNC machining, carbon fiber layups) to balance strength and weight.
Work closely with control and software teams to ensure mechanical designs are compatible with dynamic walking algorithms.
Prototype and iterate designs, conducting physical testing to refine the hardware.
Document designs, findings, and improvements to ensure knowledge transfer within the team.
General Responsibilities: Attend weekly/bi-weekly departmental & organizational RoboTUM meetings, as well as occasional spontaneous meetings as needed. Answer emails and messages within 24 hours (be comfortable using Slack). Adhere to RoboTUM policies and be willing to help when the team needs you
Minimum Qualifications
Passion for robotics, biomechanics, or mechanical design.
Basic experience with CAD software (e.g., SolidWorks, Siemens NX, or Fusion 360).
Understanding of mechanical structures, kinematics, and statics/dynamics.
Ability to collaborate in a team environment and work on complex engineering challenges.
Willingness to learn and iterate based on testing results.
Optimal Qualifications
Experience with robotic actuators and transmissions (e.g., harmonic drives, belt systems, or tendon-driven mechanisms).
Knowledge of finite element analysis (FEA) using tools like ANSYS.
Familiarity with material science and lightweight structural design.
Practical experience in rapid prototyping and working with machining tools (CNC, laser cutting, etc.).
Experience with biomechanics or human-inspired motion analysis.
Background in control engineering to understand the mechanical-electrical interaction in dynamic walking.
