The EduExo Pro is an advanced version of our EduExo educational exoskeleton kit that includes additional content and more powerful exoskeleton hardware.
The kit contains the hardware that you need to assemble an arm exoskeleton. The handbook has several additional chapters compared to the smaller EduExo 2.0 that discuss additional aspects of exoskeleton development and technology.
The most obvious difference between the EduExo Pro compared to the other versions is its hardware. It is an entire arm exoskeleton spanning the elbow and the shoulders with a total of 3 degrees of freedom. The lifting of the shoulder joint is supported by a mechanical spring, while the elbow joint movement is supported by a motor. A force sensor in the lower arm, an angle sensor in the elbow joint, and an EMG sensor to measure muscle activity enable you to implement a wider range of control algorithms. The exoskeleton structure and joint consist mostly of metal parts and it is interfaced to your arms through cuffs and to your upper body through a vest.

The EduExo Pro handbook comprises ten main chapters introducing you to state-of-the-art exoskeleton technology. All chapters have a theoretical part that teaches you in-depth knowledge about exoskeletons. In addition, most chapters have a tutorial section that guides you through the following assembly and programming steps to build your exoskeleton with the hardware provided in the box.
Chapter 1: Introduction
The first chapter introduces the field of robotic exoskeletons - examining exoskeleton history, examples of existing systems, their functionality, and their applications.
Chapter 2: Exoskeleton Development
Who develops exoskeletons? And what do exoskeleton developers do all day? This chapter talks about the exoskeleton development process and required skills.
Chapter 3: Anatomy and Mechanics:
The third chapter covers the basics of human functional anatomy and exoskeleton mechanics. Here it gets hands-on with a tutorial on the assembly of the EduExo Pro.
Chapter 4: Mechanical Design
Time to discuss hardware design and manufacturing. Learn about technical drawing, CAD design, stress-strain analysis, and design a customized arm cuff that can be 3D printed.
Chapter 5: Electronics
This chapter teaches the basic electronics knowledge and skills needed to connect all electronic parts of the EduExo Pro safely.
Chapter 6: Software
This chapter covers the software that turns the mechanical exoskeleton into a robotic exoskeleton. It contains source code examples for all exoskeleton core functions.
Chapter 7: Basic Control Systems
Chapter seven introduces control systems. Different controllers that define the exoskeleton-user interaction are introduced, discussed, implemented, and tested.
Chapter 8: Advanced Control Systems
The most important task of the control system is to ensure that it provides support when needed. To do so, the user's movement intention and physical load are valuable information. They can be estimated using muscle activity.
Chapter 9: Virtual Reality & Video Games
Virtual realities and video games can be used with exoskeletons. They are, for example, used to increase motivation in patients that use exoskeletons for rehabilitation, e.g., after a stroke. In this chapter, we create our own video game and use the EduExo as a game controller and feedback device.
Chapter 10: Scientific Experiments
Now that the exoskeleton is finished, it is time to evaluate the support it provides systematically.
Teaching with the EduExo Pro
The EduExo Pro was designed to facilitate teaching practical courses on topics ranging from hardware design, electronics, control theory, and software design to scientific evaluation. The handbook contains all the information a student would need to assemble the exoskeleton and program basic control strategies. It is ideally suited for group work, allowing each student to contribute in a unique way (hardware, electronics, control, game design, experiments) or encouraging them to go through each step together.
The EduExo Pro can be customized in many ways, from implementing more advanced control strategies to improving the hardware. Educators have complete freedom to customize and add modules to suit their needs.
