Distributed multi-robot collision avoidance via deep reinforcement learning for navigation in complex scenarios

Int. J. Robotics Res., 2020
Developing a safe and efficient collision-avoidance policy for multiple robots is challenging in the decentralized scenarios where each robot generates its paths with limited observation of other robots’ states and intentions.

The dynamic window approach to collision avoidance

IEEE Robotics Autom. Mag., 1997
This approach, designed for mobile robots equipped with synchro-drives, is derived directly from the motion dynamics of the robot. In experiments, the dynamic window approach safely controlled the mobile robot RHINO at speeds of up to 95 cm/sec, in ...

A Model for Collision Processes in Gases. I. Small Amplitude Processes in Charged and Neutral One-Component Systems

, 1954
A kinetic theory approach to collision processes in ionized and neutral gases is presented. This approach is adequate for the unified treatment of the dynamic properties of gases over a continuous range of pressures from the Knudsen limit to the high ...

Traces of collisions within collisions

Science, 2015
Lunar Formation The Moon is widely accepted to have been created by the collision of a Mars-sized body with Earth. However, information about exactly when this event occurred is still welcome. To find out more, Bottke et al. compared models and the meteorite record with estimates of impact heating.

The Prediction of Collision

The American Journal of Psychology, 1957
No direct information is available on the factors which enter into an operator's decision as to whether two moving objects will collide, nor are there data on the accuracy with which such predictions are made. The previous studies which bear the closest relation to these problems have involved only one moving object.

Exact solution of the Korteweg-deVries equation for multiple collision of solitons

, 1971
An exact solution has been obtained for the Korteweg\char22{}de Vries equation for the case of multiple collisions of $N$ solitons with different amplitudes.
