Autonomous pallet handling is a central task in warehouse automation, yet
classical control pipelines for forklifts assume structured environments and
near-perfect pallet placement, leading to failed attempts when pallets are
positioned with significant positional and orientational variation.
Reinforcement learning (RL) offers an alternative that can learn robust control
policies directly from experience. This thesis investigates RL for autonomous
forklift pallet handling in a high-fidelity simulated warehouse environment
built in NVIDIA Isaac Sim and Isaac Lab, focusing on robustness to variation in
pallet yaw and forklift starting position across both ground-level and
rack-level scenarios. The work was conducted in collaboration with Toyota
Material Handling Europe.
The task was formulated as a Markov decision process and solved with Proximal
Policy Optimization using privileged state information, isolating the control
problem from perception. Three training strategies were compared under
equivalent conditions: a no-curriculum baseline, a success-predictor curriculum
(SPCL), and a demonstration-based curriculum (DCL). A reward function was designed for the task, and an ablation study quantified the contribution
of each shaping component. The best strategy was then evaluated across three deployment scenarios.
The results show that SPCL achieved the best performance among the training strategies, with a final success rate of approximately 92%, compared to 87% for the baseline and 85% for DCL, while reaching an 80% success rate in 59 M timesteps against 78 M and 116 M. DCL matched the baseline in success rate but produced roughly three times the collision rate. The ablation study showed that each reward component served a distinct role, with progress, stop, and smoothness terms being essential for learning. Evaluated across three deployment scenarios, the selected policy reached success rates of 90.8%, 81.3%, and 61.7%, with the lowest performance on the elevated rack-level configuration.
