Partnering opportunity

Robotic ankle for research.


A Spanish technological company has developed a robotic ankle for research related to rehabilitation, biomedicine, and sports. It is an open system that can be fully controlled and programmed by the researcher and is equipped with different sensors. The company is looking for commercial agreements with technical assistance.

Partner sought

The Spanish company is looking for international partners in the healthcare and sports sectors willing to commercialize this solution to hospitals, research centres, and any other organization related to healthcare or sports. The kind of partnership sought is commercial agreement with technical assistance.


Different kinds of orthopaedic systems are used by researchers conducting investigations related to the lower-limbs movement. The problem is that most of them are not intended for research but for the final user, so it is not possible to control and program them and are not equipped with sensors. Therefore, if the researchers want to use them, they need to develop a control software and incorporate the required sensors. In this context, the Spanish technological company has developed a robotic ankle that has been specially designed to fit the researcher's needs in the fields of rehabilitation, biomedicine and sports. This technology allows controlling the quantity of movement and the velocity in the joint movement. Also, it incorporates encoders to estimate angular position and two pressure sensors inside the sole. The technology package incorporates all the systems needed to start working immediately, including a battery pack that lasts for 5 hours. Technical features regarding this solution are the following: -Total package weight: 1.865 gr (including battery). -5 hours LiPo (Lithium Polymer) battery. -Communications: CAN (Controller Area Network), Wi-Fi, Bluetooth -Sensors: joint position, joint interaction torque, foot/ground contact (heel and toe). -Actuators: 1 DoF (Degrees of Freedom), 1 motor, strain wave gearing. -Firmware free updates. The company is looking for partners in the healthcare and sports research sector willing to cooperate under a commercial agreement with technical assistance.

Advantages and innovations

-It is the first robotic ankle in the market ready to be used in research related to rehabilitation, biomedicine, and sports. It allows the researcher to adjust the control parameters of the system according to the investigation needs. On the contrary, the rest of the robotic ankles in the market are not intended for research but for the final patients so are designed with a completely closed architecture. -The robotic ankle can be customized according to the researcher needs. -The system is light and compact.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
