Learning Precise 3D Manipulation from Multiple Uncalibrated Cameras

Akinola, Iretiayo, Varley, Jacob, Kalashnikov, Dmitry

Understand

In this work, we present an effective multi-view approach to closed-loop end-to-end learning of precise manipulation tasks that are 3D in nature.

  • Our method learns to accomplish these tasks using multiple statically placed but uncalibrated RGB camera views without building an explicit 3D representation such as a pointcloud or voxel grid.
  • This multi-camera approach achieves superior task performance on difficult stacking and insertion tasks compared to single-view baselines.
  • Single view robotic agents struggle from occlusion and challenges in estimating relative poses between points of interest.
