CycleManip introduces an imitation learning framework that enables robots to perform cyclic manipulation tasks reliably by integrating efficient historical perception and understanding mechanisms. It achieves superior performance on both simulated and real-world cyclic tasks, reducing cycle count deviation and improving success rates, while also proposing a new benchmark for this domain.

Key insights

• Reliably performing non-Markovian cyclic manipulation tasks requires an explicit and efficient mechanism to incorporate historical context, beyond short-term observations.
• A cost-aware sampling strategy can effectively expand the observation window without incurring prohibitive computational costs, by distinguishing between high and low overhead observations.
• Guiding the policy with an auxiliary task to predict its progression through a cycle enables a deeper understanding of the task's temporal structure, leading to more accurate termination and execution.
