Vision-Based Multi-Task Manipulation for Inexpensive Robots Using End-To-End Learning from Demonstration

Rahmatizadeh, Rouhollah, Abolghasemi, Pooya, Bölöni, Ladislau et al.

Understand

We propose a technique for multi-task learning from demonstration that trains the controller of a low-cost robotic arm to accomplish several complex picking and placing tasks, as well as non-prehensile manipulation.

  • The controller is a recurrent neural network using raw images as input and generating robot arm trajectories, with the parameters shared across the tasks.
  • The controller also combines VAE-GAN-based reconstruction with autoregressive multimodal action prediction.
  • Our results demonstrate that it is possible to learn complex manipulation tasks, such as picking up a towel, wiping an object, and depositing the towel to its previous position, entirely from raw images with direct behavior cloning.
