Abstract
This article focuses on indirect coil guns used for launching non-magnetic objects. A mechatronic model, coupling electrical, mechanical, and electromagnetic models, is proposed. This model is applied to the optimization of a kicking system used on limited size robots for propelling real soccer balls at the RoboCup. Working with an existing coil gun, we show that fine tuning its setup, especially the initial position and the length of the non-magnetic plunger extension, leads to an increase in the ball speed of 30 % compared to previous results.
Highlights
An electromagnetic launcher (EML) is a system which uses electricity to propel a projectile [1].A coil gun is a type of EML which has the ability to launch magnetic objects by converting electrical energy into kinetic energy using a coil [2].Launching non-magnetic objects cannot be achieved using coil guns directly because these objects are not affected by the magnetic field; it can be done with an “indirect coil gun”, using a magnetic plunger accelerated by a coil, which propels the non-magnetic object by continuous contact or elastic shock
We have chosen to optimize a kicking system used at the RoboCup in the Middle Size League, which is a robot soccer competition where the robots have a limited size and weight in which to embed a soccer ball launching systems
We have proposed a method for optimizing indirect coil gun operation
Summary
An electromagnetic launcher (EML) is a system which uses electricity to propel a projectile [1]. Launching non-magnetic objects cannot be achieved using coil guns directly because these objects are not affected by the magnetic field; it can be done with an “indirect coil gun”, using a magnetic plunger accelerated by a coil, which propels the non-magnetic object by continuous contact or elastic shock Both these propelling techniques can be combined in a multi-phase EML. We have chosen to optimize a kicking system used at the RoboCup in the Middle Size League, which is a robot soccer competition where the robots have a limited size and weight in which to embed a soccer ball launching systems. The RoboCup MSL case study has been chosen due to the relevance of the trade-off regarding the optimization of the speed of the ball being kicked by the indirect coil gun and the strict size constraints in the competition rules.
