    Injured robots learn to limp

    Published on May 27, 2015

    Like most computers, robots are highly efficient… until something goes wrong. But could they learn to adapt to mechanical faults? Scientists have been deliberately sabotaging walking robots to see how fast they learn to cope.

    Towards semi-episodic learning for robot damage recovery

    Published on Mar 31, 2016

    "Towards semi-episodic learning for robot damage recovery"

    Konstantinos Chatzilygeroudis, Antoine Cully and Jean-Baptiste Mouret

    Paper submitted to "Artificial Intelligence for Long-Term Autonomy" (AILTA) workshop in ICRA 2016.


    The recently introduced Intelligent Trial and Error algorithm (IT&E) enables robots to creatively adapt to damage in a matter of minutes by combining an off-line evolutionary algorithm and an on-line learning algorithm based on Bayesian Optimization. We extend the IT&E algorithm to allow for robots to learn to compensate for damages while executing their task(s). This leads to a semi-episodic learning scheme that increases the robot’s life-time autonomy and adaptivity. Preliminary experiments on a toy simulation and a 6-legged robot locomotion task show promising results.

    This video shows a 6-legged robot performing locomotion tasks despite the left middle leg being removed using our technique.

    This work was supported by the ERC project “ResiBots” (grant agreement No 637972), funded by the European Research Council.

    Learning and adapting quadruped gaits with the "Intelligent Trial & Error'' algorithm

    Published on Mar 29, 2019

    Eloïse Dalin, Pierre Desreumaux & Jean-Baptiste Mouret

    We use the IT&E algorithm (Cully et al., 2015) to learn gaits for an intact quadruped robot and to adapt to damage, in less than 35 trials (usually less than 10).

    This work received funding from the European Research Council (ERC) under the European Union's Horizon 2020 research and innovation programme (GA no. 637972, project "ResiBots")
