In the framework of the research project “Innovative systems and services for transport and production” IDEX/I-SITE CAP 20-25 (Challenge 2) and the LabEx IMobS3, and thanks to a FrenchTech chair program, a postdoctoral position is proposed for highly motivated candidates interested in computer vision and mobile robots.


Mobile robot learning with minimal supervision

context of the project

This postdoc is funded through the FrenchTech/I-SITE CAP 20-25 Chaire d’Excellence program. The candidate will be joining the Image, Perception Systems and Robotics group of Institute Pascal which has long experience in computer vision and mobile robots. This research will be conducted in the context of an ongoing collaboration between Institut Pascal and Prof. Jochen Triesch from the Frankfurt Institute for Advanced Studies (FIAS).

Scientific project and objectives

The combination of reinforcement learning and deep neural networks has led to impressive results in the past few years, such as computers outperforming humans in certain games (Mnih et al., 2015, Silver et al., 2016) and it has shown promising results in robotic tasks when some priors are available (Lilicrap et al. 2015, Finn et al. 2016). However, learning complex tasks for mobile manipulation robots without strong priors remains a challenge since only very specific behaviors may lead to any rewards. Discovering these behaviors by exploring the consequences of random movements is extremely improbable. This suggests that the learning process cannot rely on random exploration but must be structured intelligently.

In a recent PhD thesis, we have proposed a new deep reinforcement learning framework to address this problem in the context of learning visuo-motor tasks (de La Bourdonnaye et al. 2017, 2018, 2019). We have considered an object reaching task on a robotic platform comprising an active binocular vision system and a robot arm. We demonstrated stage-wise sensori-motor learning using only miminal supervision. In particular, no forward/inverse kinematics, pre-trained visual modules, expert knowledge, nor calibration parameters were used. Nevertheless, by following a stage-wise learning regime, where difficult skills are learned on top of simpler ones, the complex touching skill was learned quickly. In this postdoc project, we propose to address more challenging tasks in the context of mobility by integrating a mobile robot platform.

First, our binocular vision framework will be adapted to deal with varying backgrounds and scenes that arise when the robot is moving. Second, using additional degrees of freedom, the robot will autonomously learn to approach objects so it can touch and manipulate them. In our previous work, we have already shown how the robot can autonomously learn whether an object is within reach. Now the robot will also learn to move towards the object so that it can be reliably touched and manipulated. In the final step, the robot will autonomously learn to follow objects (or people) through the environment. We will first restrict ourselves to simulations. And consider real-robot experiments depending on progress and results.
