Nature provides animals and human beings with the ability to efficiently and safely interact with the environment. While vision, auditory and vestibular systems deliver mainly sensory information for navigation and path planning, the somatosensory system with its cutaneous (tactile) and proprioceptive receptors provide feature rich information whenever there is contact with the environment. The somatosensory system allows very fast and save cognition and reaction and is - as soon as the system is in contact with the environment - more reliable than the other parts of the perceptive system: Somatosensory information cannot easily be misinterpreted or occluded. For save, reflex like reactions very fast cognition and responses are needed. Therefore the somatosensory system processes, combines and organizes information already at receptor level and keeps the organization (somatosensory map) up to the highest processing levels in the brain. Also the nervous system conveys and processes information only if there is new information. This asynchronous, event based principle reduces the required transmission bandwidth and processing power and makes the system fast and efficient.
My research focuses on biologically plausible principles for fast and efficient tactile cognition with whole-body multimodal robotic skin and thus will enable robots to new kinds of whole-body interactions and fast reflex-like responses. I let myself inspire from nature while the goal is not to copy nature but to understand the principles nature uses to solve problems that we also have in engineering and robotics. In this way we can benefit from results of the biological optimization process which had millions of years to solve common problems while adjusting the found principles to the special needs of our artificial systems.
I’m currently working on making use of the local distributed processing units of our multimodal self-organizing robotic skin and on implementing efficient event generation in the skin cells themselves for reducing data load and processing power and improving temporal resolution.
