A robot on EBRAINS has learned to combine vision and touch
On the new EBRAINS research infrastructure, scientists of the Human Brain Project have connected brain-inspired deep learning to biomimetic robots.
How the brain lets us perceive and navigate the world is one of the most fascinating aspects of cognition. When orienting ourselves, we constantly combine information from all six senses in a seemingly effortless way – a feature that even the most advanced AI systems struggle to replicate.
On the new EBRAINS research infrastructure, cognitive neuroscientists, computational modellers and roboticists are now working together to shed new light on the neural mechanisms behind this, by creating robots whose internal workings mimic the brain.

In the Human Brain Project, Pennartz has collaborated with computational modellers Shirin Dora, Sander Bohte and Jorge F. Mejias to create complex neural network architectures for perception based on real-life data from rats. Their model, dubbed “MultiPrednet” consists of modules for visual and tactile input, and a third that merges them.
The way these networks “train” resembles how scientists think our brain learns: By constantly generating predictions about the world, comparing them to actual sensory inputs, and then adapting the network to avoid future error signals.
To test how the MultiPrednet performs in a body, the researchers teamed up with Martin Pearson at Bristol Robotics Lab. Together they integrated it into Whiskeye, a rodent-like robot that autonomously explores its environment, using head-mounted cameras for eyes, and 24 artificial whiskers to gather tactile information.
The researchers observed first indications that the brain-based model has an edge over traditional deep learning systems: Especially when it comes to navigation and recognition of familiar scenes, the MultiPredNet seems to perform better – a discovery the team now investigates further.
To accelerate this research, the robot has been recreated as a simulation on the Neurorobotics Platform of the EBRAINS research infrastructure.

ABOUT THE RESEARCHERS
Cyriel Pennartz is full professor at the Department of Cognition and Systems Neurosciences of the University of Amsterdam. He is one of the leaders of the Human Brain Project and member of its Scientific and Infrastructure Board. In this function he has been working to integrate empirical neuroscience, computational modelling of brain networks and theories on perception, memory and consciousness. Chief characteristics of his work are its multidisciplinarity and integrative approach to neuroscience, combined with a theory- and model-driven basis for in-depth experimentation and with technologically innovative capacities.
Martin Pearson is a Senior Research Fellow and theme lead for biomimetic and neurorobotics research at the Bristol Robotics Laboratory. He has a B.Eng. degree in Electrical and Electronic Engineering from Manchester University with an MSc. and PhD. in Robotics from the University of the West of England, Bristol. He has authored/co-authored 19 journal articles and over 50 peer reviewed conference papers in the fields of robotics, animal behaviour and embedded neuromorphic hardware.
ABOUT THE HUMAN BRAIN PROJECT
The Human Brain Project (HBP) is the largest brain science project in Europe and stands among the biggest research projects ever funded by the European Union. At the interface of neuroscience and information technology, the HBP investigates the brain and its diseases with the help of highly advanced methods from computing, neuroinformatics and artificial intelligence, and drives innovation in fields like brain-inspired computing and neurorobotics.
