摘要:

训练端到端的深度机器人策略需要大量特定于域、任务和硬件的数据,而这些数据的提供成本通常很高。在这项工作中,我们建议通过采用具有模块化架构的深度神经网络来解决这个问题,该架构由独立的感知,策略和轨迹部分组成。系统的每一部分都是在合成数据上或在模拟中完全训练的。数据在系统的各部分之间交换,作为示能表示和轨迹的低维潜在表示。然后在一个zero-shot传输场景中使用弗兰卡熊猫机器人arm.Results的性能进行评估表明,从RGB图像中提取的场景启示的低维表示是足够的成功训练机械手的政策。我们还介绍了一种方法的启示数据集生成,这是很容易推广到新的任务,对象和环境,不需要手动像素标记。

英文摘要:

Training end-to-end deep robot policies requires a lot of domain-, task-, and hardware-specific data, which is often costly to provide. In this work, we propose to tackle this issue by employing a deep neural network with a modular architecture, consisting of separate perception, policy, and trajectory parts. Each part of the system is trained fully on synthetic data or in simulation. The data is exchanged between parts of the system as low-dimensional latent representations of affordances and trajectories. The performance is then evaluated in a zero-shot transfer scenario using Franka Panda robot arm. Results demonstrate that a low-dimensional representation of scene affordances extracted from an RGB image is sufficient to successfully train manipulator policies. We also introduce a method for affordance dataset generation, which is easily generalizable to new tasks, objects and environments, and requires no manual pixel labeling.
