EXO / Exoskeleton Race

About the Team
RISE (Research and Innovation in Student Exoskeleton Development) is a collaboration between the Medical Engineering Department at TU Berlin and the student initiative "Sozial Engagierte Ingenieur*innen" (SEI). The goal is to develop a robotic exoskeleton to help individuals with paraplegia stand and walk. Over 100 students from diverse disciplines have worked closely with pilots to design, build, and optimise this high-tech assistive device. Since our start two years ago, the project has moved to organise into distinct yet collaborative work groups, such as concept, development, manufacturing, and training, culminating in a competitive exoskeleton for the CYBATHLON 2024.
About the Pilot
Jessica, our pilot, is a motivated and integral part of the team. She joined in early 2024 and is passionate about advancing technology to create a more accessible world. The system is currently in the concept phase and the student groups are developing the first functional samples in methodical steps.
About the Device
RISE Exo One is our debut entry for the competition. The exoskeleton represents a breakthrough for TU Berlin in hardware, software, and human-machine interaction, designed for current needs with future adaptability in mind.
The exoskeleton combines conventional manufacturing techniques with 3D-printed composite materials, ensuring strength and lightweight performance. It features six active and four passive actuators (including leaf springs) for multi-joint mobility, delivering up to 300 Nm of torque for tasks like stair climbing. It is Powered by a 48V supply with a peak output of 100A. Safety is ensured by Safe Motion technology in the hip actuators, using dual encoders for precise and secure movement, along with mechanical end stops. The system is designed for ongoing upgrades, with plans to integrate FSR sensors and IMUs for better balance control. ROS 2 enables easy future expansion, such as adding ankle actuators for improved performance on uneven terrain. The user interface, developed in close collaboration with wheelchair users, has been tested extensively. It supports multiple gait modes (standing, walking, stair climbing, squatting) controlled via crutch-integrated inputs.
Unfortunately, not all functions will be fully operational by the time of the competition, but we are very proud of our two-year development period.
