Unified Data Collection for Visual-Inertial Calibration via Deep Reinforcement Learning

1 code implementation30 Sep 2021 Yunke Ao, Le Chen, Florian Tschopp, Michel Breyer, Andrei Cramariuc, Roland Siegwart

Our approach models the calibration process compactly using model-free deep reinforcement learning to derive a policy that guides the motions of a robotic arm holding the sensor to efficiently collect measurements that can be used for both camera intrinsic calibration and camera-IMU extrinsic calibration.

Volumetric Grasping Network: Real-time 6 DOF Grasp Detection in Clutter

1 code implementation4 Jan 2021 Michel Breyer, Jen Jen Chung, Lionel Ott, Roland Siegwart, Juan Nieto

General robot grasping in clutter requires the ability to synthesize grasps that work for previously unseen objects and that are also robust to physical interactions, such as collisions with other objects in the scene.

Learning Trajectories for Visual-Inertial System Calibration via Model-based Heuristic Deep Reinforcement Learning

1 code implementation4 Nov 2020 Le Chen, Yunke Ao, Florian Tschopp, Andrei Cramariuc, Michel Breyer, Jen Jen Chung, Roland Siegwart, Cesar Cadena

Visual-inertial systems rely on precise calibrations of both camera intrinsics and inter-sensor extrinsics, which typically require manually performing complex motions in front of a calibration target.

Comparing Task Simplifications to Learn Closed-Loop Object Picking Using Deep Reinforcement Learning

1 code implementation13 Mar 2018 Michel Breyer, Fadri Furrer, Tonci Novkovic, Roland Siegwart, Juan Nieto

We learn closed-loop policies mapping depth camera inputs to motion commands and compare different approaches to keep the problem tractable, including reward shaping, curriculum learning and using a policy pre-trained on a task with a reduced action set to warm-start the full problem.
