Modification of a deep learning algorithm for distributing functions
and tasks between a robotic complex and a person in conditions
of uncertainty and variability of the environment
Abstract:
In the real world, conditions are rarely stable, which requires robotic systems to be able
to adapt to uncertainty. Human-robot collaboration increases productivity, but this requires effective
task allocation methods that consider the characteristics of both parties. The aim of the work is to
determine optimal strategies for distributing tasks between people and collaborative robots and
adaptive control of a collaborative robot under uncertainty and a changing environment. Research
methods. The paper develops a graph-based approach to task allocation based on the capabilities of a
human and a robot. The LSTM memory mechanism is built into the reinforcement learning
algorithm to solve the problem of partial observability caused by inaccurate sensor measurements
and environmental noise. The Hindsight Experience Replay method is used to overcome the
problem of sparse rewards. Results. The trained model demonstrated stable convergence, achieving a
high level of success rate of manipulation of objects. The integration of LSTM and HER methods
into reinforcement learning allows solving the problems of distributing tasks between a human and a
robot under uncertainty and a changing environment. The proposed method can be applied in various
scenarios for collaborative robots in complex and changing conditions.
