"We improve the ability to move by reinforcing mistakes," the engineer said. It would be weird. However, if a stroke patient, for example, wants to take something, but is inaccurate, the rehab robot reinforces this inaccuracy by creating a slight objection. In this way, the patient has to work harder. The learning algorithm developed by Marchal-Crespo independently determines which patient complicates the task and which one facilitates it.

In addition to Armin, there is also a horizontal running machine in the Bern open-plan office. Marchal-Crespo can then assess a patient even during exercise on a magnetic resonance tomograph. He lied, actively or actively moved his legs there with a knee-jerk robot. Researchers want to know which areas of the brain are stimulated by such specific exercises and how neurons reconnect after a stroke. He is currently trying to mimic the feeling of walking as much as possible, so that, for example, the pressure on the soles is felt.
Originally from the suburbs of Barcelona, he laughs. He was fortunate that he received a scholar for the USA at that time. Because his parents were not academic, and his father made money as a taxi driver. Her mother has always supported her and her two sisters in every way, she added. One is now a mechanical engineer in Australia, the other is a chemist in Barcelona.
Since Marchal-Crespo's man also came from the capital of Catalonia, he talks to three children between the ages of three and seven as he speaks Spanish to them, Daily life with family and work is a challenge, but also exciting and a privilege, he will look. Her husband works as an engineer at ABB in Zurich. While the family lives there, he talks to Bern four days a week. "Whenever possible, we will all be doing outdoor activities over the weekend and either walking or biking."
Virtual Reality Therapy
Marchal-Crespo is at work particularly fascinated by the sheer possibilities of the virtual world. So one of his doctoral students is now releasing a glass of VR. If you open it, you are in a virtual room where suddenly there is an apple, then a pear or other apple hangs in the air. With a controller you now have the ability to control a ball exactly with these fruits and at the same time count the fruits.
