Why self-learning Embodied Agents?

Our approach of Qualitative Causal Models: position paper. Presented as a poster at IMOL 2025.


Introduction

The goal is to let robots learn themselves starting from an ‘empty’ brain to control their world. This will make robots more robust and versatile since they will be able to adapt to new environments and changes in their environment.
Humans are the example. Babies are born without any skills, they even don't know how to control their muscles/limbs. They just have the skill to learn... And become experts in understanding and controlling the world. Better than animals preprogrammed with instincts. Or at least more versatile.

Our strategy is to start with incrementally learning the system's structure—dependencies, causal connections and phase transitions—by doing a qualitative analysis rather than learning a monolithic quantitative model.
The result is a decomposition based on reusable, monotonous components that are then transformed into quantitative models. Learning takes place gradually and is closely intertwined with exploration and exploitation.

Current work

We are currently working on the Qualitative Causal Model framework to let our robots explore, learn and perform tasks.
It is based on the following preliminary studies:
