The EduExo
The EduExo is a robotic exoskeleton kit that you assemble and program yourself. It contains the hardware that you need to build an elbow exoskeleton. An accompanying handbook contains a tutorial that will guide you through the different assembly steps. In addition, the handbook provides background information on exoskeleton history, functionality and technology. In the end, you will have a good understanding about exoskeleton technology and its application, together with hands-on experience building and programming your own robotic exoskeleton.
The EduExo hardware combines off-the-shelf components (motor, force sensor and Arduino microcontroller) with a rigid exoskeleton structure and cuff interfaces.

Project Background
When thinking of robotic exoskeletons, movies such as Iron Man, Aliens or Elysium may come to your mind. But already today there are many real world exoskeletons that support rehabilitation of stroke patients, enable people with paraplegia to walk again or assist workers lifting heavy objects.
And todays systems are just the beginning of a very promising and quickly growing field that is in need of many skilled talents within the next years.
Due to the novelty of the field, getting involved and learning about robotic exoskeletons is difficult as learning material or even exoskeleton course or classes are not widely available yet. This is made even more difficult as learning about exoskeletons is not possible by theory alone, but also requires practical hands on experience (you have to see and feel it to understand it). Unfortunately, the necessary exoskeleton hardware is expensive and there are no dedicated and affordable learning devices available. This is what we intend to change with the EduExo.
The EduExo recently won the Wearable Robotics Association Innovation Competition in April 2017.
This prize was awarded to us by a jury of CEOs and CTOs of leading exoskeleton companies, highlighting their demand for exoskeleton talents. Click on the banner above to learn more.

What You Will Learn
By going through the tutorial, you will learn how the mechanical design resembles the human anatomy, how to connect the sensors and the electronics board, and how to design and program a control system. Further, you will connect the exoskeleton to a computer and learn how to use it as a haptic device in combination with virtual reality. Each chapter of the tutorial introduces one topic, starting with the necessary theoretical background, followed by a set of exercises that the user implements with the hardware.
The following topics are covered:
Exoskeleton Introduction
The first chapter will introduce you to the field of robotic exoskeletons and to exoskeleton technology. What are robotic exoskeletons? What are they used for? How do they work? Since when are they being developed and used? The introduction will get you started and inspired.
Mechanics and Anatomy
This chapter covers the basics of human functional anatomy and exoskeleton mechanics: How does the human create forces and is able to move? How does the exoskeleton provide support? How is the exoskeleton designed to match the form of the human and how is it attached? During this tutorial, you assemble and wear the exoskeleton.
Electronics and Software
The next chapter covers the electronic and software components that convert the mechanical exoskeleton into a robotic exoskeleton. You will connect the electronic components, sensors and actuators to an Arduino microcontroller, and write the basic software routines to read sensor signals and control the motor.
Control Systems
The control system defines the behavior of the exoskeleton. After a general introduction into exoskeleton control, different controllers that define the exoskeleton-user interaction are introduced. Step-by-step we discuss, implement and test them.
Virtual Reality and Video Games
Video games and virtual reality simulations are well-established methods in use with medical exoskeletons. They are used to increase motivation in patients that use exoskeletons for rehabilitation, e.g. after a stroke, to keep them engaged even in therapy sessions that can last for hours. You will learn how to create a computer game, connect the exoskeleton to your computer (Windows PC) and use it as a game controller.
The Muscle Control Extension
The muscle control extension adds a muscle activity sensor (EMG) and a new chapter to the handbook.
Measuring the user's muscle activity to estimate movement intentions is an interesting way to control a robotic exoskeleton and the EduExo will show you how it can be done.
The extension contains a muscle activity (electromyography-EMG) sensor, cables to connect it to the Arduino microcontroller and electrodes to connect to the user to get you started.
We chose to offer it separately because the EMG sensor is comparatively expensive. This way you can decide for yourself if you want to learn about this advanced robotic exoskeleton control approach or if you prefer to first get started with the basic kit. The extension will be offered separately after the full release of the kit.
Beyond the Tutorial
The EduExo tutorial introduces you to all you need to know for a deeper understanding of robotic exoskeletons. But, of course, there are many more possibilities of what you can do, and the EduExo is the perfect platform for your own experiments and ideas. Maybe you want to develop your own control algorithm or a new computer game that can be controlled with the EduExo? Or you want to learn more about mechanical design; you can start by designing new parts and interfaces to optimize the exoskeleton for your own arm anatomy. If you have implemented a great idea with the EduExo, we will be happy to share it on our website and YouTube channel.
Why we need your support
We have working prototypes of all components and have written many sections of the handbook. But we still have to finalize the hardware, finish handbook and tutorial, scale production and order the components. Therefore, we need your support. By contributing you will help us to create a STEM education kit to make robotic exoskeleton technology truly accessible. In return, you will be among the first to get the EduExo and gain knowledge and skills in a seminal field
Stretch Goals
We have reached 150% of our minimum funding goal (or 12k CHF)! Thank you so much for the support! As we have more than two weeks to go, we added stretch goals in case the campaign gets even more support. Of course, the stretch goals will benefit all backers.
The Rewards
Project Timeline
The EduExo project started as a side project (besides a PhD in robotic exoskeleton research) and has been in development from early 2016. But only with the beginning of this year we were able to commit more time to turn the prototypes into a product to offer the EduExo to interested users, schools and universities. With your support, we expect to finish the development within the next months and start shipping in August. When we fulfilled all Kickstarter rewards, the EduExo kit will be fully released.

What the EduExo is not
To make sure that your expectations match our intentions, here are the things that the EduExo is not:
- It is not a medical device that is intended to be used for any kind of therapy or medical application.
- It is not an exoskeleton that will make you super strong. The actuation is weak. It is only intended to illustrate basic exoskeleton principles while being affordable and safe. You will not be able to do more chin-ups. It rather provides a gentle guidance of your voluntary movements.
- It is not a plug-and-play device that works out of the box. You have to make it work, that is a feature!
Requirements
The EduExo is designed for users that are new to robotic exoskeletons. Basic programming and electronics skills are benefitial, but you can learn everything you need while using the kit. The tutorial includes step by step explanations and sample solutions.
To use the EduExo some preparation is necessary. Most of the electronics can be connected without soldering and a breadboard and jumper cables are included to get you started. The force sensor requires soldering to connect it. For that you need a soldering iron and some basic tools. Don't worry If you have not done this before. The equipment is not expensive and we include a step-by-step explanation in the tutorial. The Muscle Control extension also requires soldering. To program the exoskeleton (Arduino UNO microcontroller) you need to install the Arduino IDE. It is for free and can be downloaded on the Arduino website for several operation systems. For the "virtual reality and video games" chapter, you need to install the Unity 3D game engine. It is for free for private and non-commercial use but requires registration. So far we have only tested the Windows (7 and 10) version of it and cannot promise that the communication between exoskeleton and game works (similar) on other platforms.
Due to shipping regulations no battery is included. For all the tutorials we use the Arduino's power out to supply the sensors and the motor. While it is limited in power, it is sufficient for the tutorial. You can expand it later with a motor shield and even replace the actuator if you like. The Arduino itself has to be battery powered when wearing the exoskeleton (safety).
Shipping and Taxes
We are shipping the EduExo from Switzerland and ship worldwide. The shipping fees are listed with the rewards and will be added during checkout. You are responsible for any taxes, customs charges, etc. required by your country. We will attach the bill to the parcel and the product will be labeled as 'educational robotics kit' with its real value (what you paid for it). This should minimize any delay in case it gets processed by customs.
Risks and challenges
We use mostly off-the-shelf components that are widely available. But sometimes products change, are (for some time) not available and in stock or are discontinued. To minimize these risks we use parts which are interchangeable with little adaptation of the design.
In case we run into supply problems and have to adapt the design, it could delay manufacturing and shipping of the boxed kits. If you choose the maker edition (3D print it yourself), we will send you new STL files in case we update the design because of component supply problems.
