Dynamical trajectory generation with collision free using neural networks

Abstract

To dynamically generating trajectory with collision free is very important but difficult for the robots in a nonstationary environment. In this paper, the real-time trajectory generation and obstacle avoidance are studied using biologically motivated neural network approaches. The optimal trajectory is generated through the neural dynamics of a topologically organised neural network. Each neuron of the neural net is characterised by a shunting equation or an additive equation. This model is computationally efficient and its stability is guaranteed. These neural network approaches were applied for solving maze-type problems, dynamically tracking moving target, and avoiding varying obstacles. The model parameter sensitivity and model variations are discussed. Simulations are included to demonstrate the proposed approaches.
