A novel approach to compensate delay in communication by predicting
teleoperator behaviour using deep learning and reinforcement learning to
control telepresence robot
Abstract
Robots with telepresence capabilities are typically employed for tasks
where human presence is not feasible due to geography, safety risks like
fire or radiation exposure, or other factors like any epidemic disease.
Time delay is a significant consideration in controlling a telepresence
robot. This study proposes a deep learning-based approach to compensate
for the delay by predicting the behaviour of the teleoperator. We
integrate a recurrent neural network (RNN) based on the Long Short-Term
Memory (LSTM) architecture with the reinforcement learning-based Deep
Deterministic Policy Gradient (DDPG) algorithm. The proposed method
predicts the teleoperator’s angular and linear controlling commands by
using data gathered by embedded sensors on the specially designed and
built telepresence robot. Simulations and experiments assess the
operation of the proposed technique in Gazebo simulation and MATLAB with
ROS integration, which shows 2.3% better response in the presence of
static and dynamic obstacles.
