Khepera bots autonomously form up and roll out

first_imgIt can be difficult to coordinate a group of robots. Just watch any of the recent Transformers movies. In the real world, however, having robots effectively work together is a tricky thing. This difficulty can crop when it comes to formations. Ted Macdonald has sought to remedy this problem.Macdonald did his graduate work in the Georgia Robotics and Intelligent Systems lab (GRITS) at Georgia Tech. His thesis centered on the problems with multi-robot cooperation. In some scenarios, the robots drive to the closest available position, but this can result in multi-robot collision. In most cases, the locations are preset which can be cumbersome when obstacles arise.AdChoices广告What Macdonald sought to do was to develop an algorithm that would enable the robots to work without preset locations. Ted’s algorithm hinges itself on the robots knowing the assigned formation and the relative location of other robots in the formation. With this knowledge, each robot is able to autonomously determine where to go, and they are also able to recalculate their route should there be any disturbances along the way.The robots can all work on the same level, or a variable can be introduced. Macdonald modified his algorithm to include a leader robot, on Optimus Prime of sorts that doesn’t work on the same level the rest of the group. The leader could be controlled by a human, have a desired position, or any number of commands and it’s the leader’s actions that will determine what the rest of the group does.Ted recently released a video displaying the leader algorithm in action. The follower robots, each outfitted with a platform, can be seen coordinating around the leader’s movements. They form a four-piece landing platform for a quadrotor that tracks the robots’ movements.Read more at Ted Mcdonald, via Engadgetlast_img read more
