About Us

Lambda Health System was founded in 2015, in Yverdon-les-Bains, Switzerland, and wants to democratize advanced robotic assistance for the rehabilitation of the locomotor system.

We develop solutions to help people recover from traumas involving the locomotor system

We do our best to make it as easy as possible to use for both patients and therapists

We help therapists to enhance their programs with new and innovative approaches.

And we do it in a cost effective way to make it available for the majority of rehabilitation centers.

Prof. Dr. Francis Degache
UNIL & HESAV Professor

Francis is currently Associate professor in the University of Health Sciences (HESAV) of Lausanne. He did his PhD on different training modalities in chronic heart failure patients. He is currently developing new methods of evaluations and training under hypoxia conditions in disabled subjects. He specialized in “physical activity and health”. He aims at investigating the effect of regular physical activity on health in different kind of diseases. Recently, he used hypoxia model to explain neurophysiologic process (i.e. postural stability) in healthy subjects. It is noteworthy that Professor Degache is also internationally recognized in the field of muscular isokinetic evaluations.

Prof. Dr. Reymond Clavel
Professor Emeritus EPFL

Reymond, obtained his degree in mechanical engineering and his PhD degree in parallel robotics at EPFL. After nine years of gathered experience in industrial plants (research and development), he was appointed professor at the EPFL in 1981. He was consecutively entrusted with the following positions: Head of the department, President (dean) of the lecturers’ board of micro engineering and, in 1993, Director of the Laboratory of robotics’ systems (LSRO). His research topics where high speed and high precision robotics, medical robotics’ applications, surgical instrumentation and precision mechanisms. Reymond is at the origin of 30 patents.

Prof. Dr. Stéphane Gobron
HE-ARC Professor

Stéphane is Professor at the University of Applied Sciences HE-Arc, where he leads the Graphics Team. His research interests mainly focus on Serious Games for Health and geometric modeling applied to the field  of radiotherapy. He recently wrote a book on WebGL, i.e. real time computer graphics for Internet. Concerning the LHS, Stéphane's team currently focuses on the Serious Games developments.

Lambda Health System can count on the support of different institutions.

Medical partners

Ingénierie & Santé

A Health-Engineering platform was developed during the last years to federate engineers and health professionals for common realizations. The Lambda robot is a pilot project for this new interesting structure.


The Lausanne University hospital and particularly its service of neurorehabilitation is a key partner for the medical input since the early days of LHS. The CHUV is currently the sponsor of the first clinical trials of the Lambda robot. Practicians of the service of neurorehabilitation are co-investigator of this study.


The University of Health Sciences of Lausanne and some of its physiotherapists have collaborated during the Lambda robot development to ensure usability for the therapist and usefulness for the patient. A physiotherapist of the HESAV is also co-investigator in the Lambda robot first clinical trials.

Academic partners


The University of Applied Sciences of Neuchatel, is our close partner for all computer graphics challenges, including Serious Games and Virtual Reality using head-mounted display. The current Serious Game platform is the result of more than 3 years of their work and a few Bachelor and Master Thesis – see the Graphics Team, "Groupe de Compétence Imagerie"


LHS is a spin-off of the University of applied Sciences of Yverdon-les-Bains. Since the early days, and for the future, it is our privileged partner for R&D. A lot of bachelor or master thesis linked to LHS have been done in the field of engineering or marketing and finances.


Located in Geneva, the Robotics Laboratory of hepia is our partner for the development of all robot motion control algorithms. Several bachelor and master thesis have been achieved and are currently in progress on this topic.


The Center for Technology Transfer of the University of Applied Sciences of Canton de Vaud helps us to valorize the company. As the winner of the HEIG-VD Start-up grant 2013, LHS disposes of a seed funding to develop business and an access to the services of the University.

Furthermore, our start-up is currently in the phase 2 of the CTI-Start-up Coaching process.

Venture Kick!

Turning scientific innovation into entrepreneurial activity and job creation is the basis of societal and economical prosperity. In the very early stages, startups bear very high risk that are neither carried by public money nor by private investors. That's why Venture Kick was created to support seed stage startups, like our!


GENILEM is a non-profit organization founded in 1995. Its mission is to support the creation of innovative companies in all areas. Constituted as a network, it works with other independent antennas in the German et French-speaking parts of Switzerland. LHS has the chance to benefit from a coaching of 3 years given by GENILEM experts.
