In this video, we are honored to showcase the in-depth application of CubeMars products in open-source projects from top universities worldwide.
The OpenExo open-source modular exoskeleton project developed by the team at Northern Arizona University successfully adopts CubeMars AK Series joint motors as the core power source, providing powerful and precise drive performance for key joints such as the hip, ankle, and elbow.
OpenExo is dedicated to creating a fully open-source and modular wearable robotics framework, and CubeMars high-performance motors serve as the ideal power solution to bring this vision to life.
The core goal of the OpenExo project is to make exoskeleton technology more accessible and easier to develop.
However, designing powered modules for human joints presents extremely demanding challenges:
Extreme balance between size and weight:The motor must be compact and lightweight enough to avoid adding extra metabolic burden to the user.
High torque output:Hip and ankle joints require significant assistance forces during walking and running.
Modularity and cost-effectiveness:As an open-source project, components need to be easy to obtain, plug-and-play, and suitable for university research budgets.
To overcome these challenges, the research team at Northern Arizona University conducted extensive evaluations and ultimately selected the CubeMars AK Series (especially the AK80-9 V3.0 KV100) as the joint actuator for the exoskeleton.
Its key advantages perfectly match the requirements of OpenExo:
Excellent Torque Density & Compact Design: The AK80-9 delivers up to 38 Nm peak torque while maintaining an extremely compact size and lightweight structure.This high torque density enables the actuator to easily handle the heavy load requirements of hip and ankle joints while keeping the overall exoskeleton lightweight.
High Integration, Perfectly Matching the Modular Concept: CubeMars AK Series motors integrate a brushless motor, planetary gearbox, dual encoders, and FOC driver into a single compact unit.This plug-and-play design greatly simplifies wiring and mechanical assembly of the OpenExo structure, allowing developers to focus more on higher-level algorithms and gait control.
Precise Control and Safe Human-Robot Interaction: Thanks to advanced FOC control algorithms and low cogging torque design, AK Series motors provide excellent force-control response.During user movement, the motor can deliver smooth and compliant assistance, ensuring safer and more comfortable human-robot interaction.
Through this video, you can directly observe the outstanding performance of the CubeMars-powered OpenExo exoskeleton in the following scenarios:
Hip joint module:Demonstrates the strong flexion and extension assistance provided by the AK80-9 during the walking cycle.
Ankle joint module: Shows the motor's rapid response and high dynamic output during plantarflexion and dorsiflexion movements.
Elbow joint module:Demonstrates precise torque control of the upper-limb exoskeleton during carrying and lifting assistance tasks.
Whether you are developing an open-source exoskeleton like OpenExo, a quadruped robot, humanoid robot, or robotic arm, CubeMars provides cost-effective miniature actuator solutions tailored to your needs.
