At present, robots typically require extensive training to successfully accomplish a single task. However, to truly enhance their usefulness in real-world scenarios, robots should possess the capability to perform multiple tasks effectively. To address this need, various multi-task reinforcement learning (RL) algorithms have been developed, including multi-task proximal policy optimization (PPO), multi-task trust region policy optimization (TRPO), and multi-task soft-actor critic (SAC). Nevertheless, these algorithms demonstrate optimal performance only when operating within an environment or observation space that exhibits a similar distribution. In reality, such conditions are often not the norm, as robots may encounter scenarios or observations that differ from those on which they were trained. Addressing this challenge, algorithms like Q-Weighted Adversarial Learning (QWALE) attempt to tackle the issue by training the base algorithm (generating prior data) solely for a particular task, rendering it unsuitable for generalization across tasks. So, the aim of this research project is to enable a robotic arm to successfully execute seven distinct tasks within the Meta World environment. To achieve this, a multi-task soft actor-critic (MT-SAC) is employed to train the robotic arm. Subsequently, the trained model will serve as a source of prior data for the single-life RL algorithm. The effectiveness of this MT-QWALE algorithm will be assessed by conducting tests on various target positions (novel positions). In the end, a comparison is provided between the trained MT-SAC and the MT-QWALE algorithm where the MT-QWALE performs better. An ablation study demonstrates that MT-QWALE successfully completes tasks with a slightly larger number of steps even after hiding the final goal position.

该研究旨在用多任务软演员-评论家算法（MT-SAC）培训机械臂，以使其能够在Meta World环境中成功执行七项不同任务。接下来，训练模型将作为单一生命强化学习算法的先前数据，并通过在各种目标位置（新颖位置）进行测试来评估MT-QWALE算法的效果。最后，通过比较经过训练的MT-SAC和MT-QWALE算法，发现MT-QWALE的表现更好。消融研究表明即使隐藏了最终目标位置，MT-QWALE也能够成功地完成任务，并且所需的步骤略多。
