First testing after revision

9. December 2019

After intensive weeks of work and changes on the exoskeleton, our pilot Thomas Krieg has recommenced training with it.
During the revision of VariLeg enhanced, a more reliable footplate had been designed and produced. It is now made of aluminum instead of laminated carbon. A modular sole allows adapting it to the needs of the pilots Thomas Krieg and Rolf Schoch.
Additionally, a change was made to the electronics box, which contains all major electronic components. This package got smaller and more reliable.
The test went successful, and with the results, further improvements can now be made by our engineering team.
A team of EKZ accompanied the test session and had an interview with Thomas.

VariLeg and HSR enhanced at Swiss Handicap in Luzern

29. and 30. November 2019

From 29.-30.11.2019 visitors at Swiss Handicap had the chance to see the exoskeleton VariLeg enhanced and the wheelchair ZED evolution by HSR enhanced. Both teams were at the booth of CYBATHLON and presented their race-exo and –wheelchair built for the CYBATHLON 2020 in Zürich.
Besides a static display of both prototypes, there were three demo-runs per day with the wheelchair tackling two CYBATHLON obstacles. The wheelchair was piloted by Florian Hauser, gold medalist at CYBATHLON 2016 in Zürich and at CYBATHLON Wheelchair Series 2019 in Kawasaki.
VariLeg enhanced was in the Tele1 news with an interview by exo-pilot Thomas Krieg and CYBATHLON-initiator Robert Riener (in German):

VariLeg enhanced went live on Japanese TV NHK World!

Japan's national TV visits VariLeg enhanced

25. September 2019

The Japanese national broadcasting organization NHK  visited us at HSR! They filmed our exoskeleton demo and interviewed our paraplegic pilot Thomas Krieg.

Paraplegic pilot Thomas Krieg: «I'm not the kind of guy who just sits around»

22. September 2019

„It’s been over four years since Thomas Krieg ended up in a wheelchair. Today, he tells us how he got back on his feet.
As a child, he played football, and later he became a bobsledder. He was a competitive athlete when the accident happened. Today, he has lost 37cm of leg circumference, and he only trains his upper body at the gym. Despite this, he still has a fighting spirit, the humour and the joy of life. In this portrait, he explains how he stays the same even though everything has changed.“

CYBATHLON experience at HSR

20. September 2019

The “CYBATHLON Experience at HSR: Next generation exoskeletons” gave visitors the chance to experience how paraplegic people can climb stairs again thanks to state-of-the-art assistance technology.  At the University of Applied Sciences Rapperswil (HSR), VariLeg enhanced and TU Delft’s Project March  showed how current exoskeletons make standing, walking, climbing stairs and standing up possible for their paraplegic pilots. Thank you to our exopilot Rolf Schoch!
The evening before, on September 19th, interested parties also had the opportunity to attend the panel discussion „Walk again? Perspectives on the current status of exoskeletons“. Experts with a medicine, research and industry background discussed the potential of exoskeletons for paraplegic people, the technical hurdles still to be overcome and the stumbling blocks between research and everyday use that still have to be removed.

CYBATHLON at Weltklasse Zürich

27. August 2019

The ETH Zurich CYBATHLON together with Weltklasse Zürich hosted a number of thrilling competitions at the Zürich main station. Commuters had the possibility to find out how innovative technology can assist people with disabilities in everyday life. There, our VariLeg enhanced pilot Thomas Krieg participated in the powered exoskeleton race! Thank you to Elektrizitätswerke des Kantons Zürich (EKZ) for supporting the sport we love.
