EduExo Pro

Educating Future 

Exoskeleton Pioneers

The EduExo Pro is an advanced exoskeleton kit that offers universities an accessible and cost-effective way to integrate exoskeleton technology into higher education and research.       

The EduExo Pro kit includes all the components needed to build an arm exoskeleton that spans the shoulder and elbow joints. Combining this hardware with a comprehensive handbook, it connects theoretical concepts to hands-on experience and supports its users in grasping fundamental principles, acquiring practical skills, and developing the confidence and mindset needed to develop real-world solutions.              
 

In educational settings, it offers a project-based exoskeleton learning experience that fosters critical thinking, creativity, and collaboration among students from diverse backgrounds, including engineering, health sciences, and medicine.

The Handbook

The EduExo Pro handbook is a comprehensive resource with over 180 pages. It explores various aspects of exoskeleton technology, offering valuable knowledge and skills.

Organized into ten main chapters, it covers a broad range of topics crucial for understanding modern exoskeletons, including human anatomy, mechanics, design, electronics, software, control systems, virtual realities and video games, and scientific experiments.

 

Each chapter begins with an introduction to the theoretical background of a topic. Most chapters then continue with a practical tutorial section that enables readers to combine theory with hands-on practice. These tutorials are structured to guide users step by step in building and programming the EduExo Pro exoskeleton, deepening their understanding of the theory and training their practical skills.

In educational settings, the handbook's structure allows individuals or groups to go through it step by step or divide it among group members, with each member specializing in a different topic.

exoskeleton technology

The Hardware

The EduExo Pro is designed as a versatile exoskeleton platform that reduces the time and resources educators need to prepare hands-on, project-based learning experiences.

The EduExo Pro hardware has been optimized to meet the needs of higher education and research. It is easy to assemble, operate, and maintain, and the hardware features many aspects of professional, modern exoskeletons to enable the user to train highly relevant skills and access state-of-the-art technology.


The box provides all the parts required to build a full arm exoskeleton with a 2-degree-of-freedom Shoulder joint and a 1-degree-of-freedom Elbow joint. A mechanical spring in the shoulder can support the user's arm against gravity, and a motor in the elbow joint allows active, programmable arm support. Different sensors help measure movements, forces, and even human biosignals, which are then used to program and test various control systems.

Hardware Components and Features Overview

  • 2 degrees of the freedom shoulder joint, with shoulder lifting supported against gravity by a mechanical spring with easily adjustable pretension, enabling students to experience different levels of support.

  • 1 DoF-powered elbow joint. The motor provides around 5 Nm of torque.

  • Force Sensor in forearm cuff to measure human-exoskeleton interaction forces.

  • Angle Sensor in Elbow joint.

  • An Arduino Nano 33 IoT allows you to program the main exoskeleton control system, read sensors, and control the motor.

  • IMU Sensor (on Arduino Board) located in the upper arm allows movement detection and static pose estimation.

  • Electromyography sensor to measure muscle activity and use it for advanced control concepts. The sensor is shipped with 50 electrodes, allowing for extensive experimentation before replenishing supplies.

  • Easy to assemble: With prior assembly and soldering experience, the first EduExo Pro takes around 3-4 hours. If you build more than one, the subsequent units can be assembled in around 1-2 hours.

  • Robust and reliable design, optimized for classroom use: thanks to a custom-made PCB, little risk of cable clutter and assembly errors and enhancing overall robustness.

  • Easy battery access: Battery replacement is quick and straightforward, facilitating uninterrupted use.

  • Optional external power supply: Available for easier programming, preparation, debugging, and testing.

  • Push buttons can be pre-programmed with various behaviors, allowing for quick and easy demonstrations or testing of different programs.

  • Versatile assembly options: The kit can be assembled as either a left- or right-arm exoskeleton. If you have two kits, you can easily combine them to create a full upper-body exoskeleton.

A versatile education and
research platform
The EduExo Pro

The EduExo Pro hardware was designed to be modifiable and expandable, offering its users many possibilities to adapt it if
they want for their classrooms
and projects.

Several open ports allow additional components, such as sensors, to be connected to the microcontroller. The cuffs and covers are all 3D printed and can exchanged with your own designs to customize it.

New games can be developed to create unique, immersive experiences using the arm exoskeleton as a controller and haptic feedback device. Relying on well-known Software frameworks such as the Arduino Microcontroller or the Unity 3D game Engine, users will find a ton of resources that allow them to explore these technologies further and adapt the EduExo Pro as they wish.

 

This allows you to customize the EduExo Pro according to your needs or simply get creative and try new ideas that go beyond the content of the handbook.

We use the EduExo Pro in the practical course “Haptic Control of an Arm Exoskeleton” for Mechanical Engineering students. This lab is held every week during the semester for several groups of students, each working with their own EduExo Pro. The EduExo Pro provides a great teaching platform and allows us to connect theoretical knowledge with practical experience. The students love it!

I am a second-year PhD student working on the development and control of upper-limb exoskeletons to assist patients with Duchenne Muscular Dystrophy. The EduExo Pro from Auxivo provided a straightforward and easy-to-set-up platform, allowing me to test my initial ideas quickly. The frame of the device is made with high precision and quality, offering a robust structure for testing.
