We designed a new type of Micro Autonomous Robotic System which size is 20" cubic. The conventional line trace robot we have introduced in Video Proc.'94 has wire for energy supply and its logic is simple and fixed. The MARS is full autonomous robotic system, that is, actuator, sensor, computer, and battery are build in the body. And we can transmit and upload programs by infrared ray, achieve different kinds of behaviors depend on the program. This communication and programmable function becomes main features of the MARS. We show 3 experimental results, which are the photo following behavior, the photo avoiding behavior, and the line trace behavior. The program of each behavior is uploaded by wireless.
AbstractReal experiments in mobile robotics are necessary and new tools need to be developed to make this experimentation easier and efficient. To reach this goal a miniature mobile robot, named Khepera, has been developed: it has a cylindrical shape measuring 55 mm in diameter and 30 mm in height. Due to its small size, experiments can be performed quickly and cost-effectively on a desk, as demonstrated in the video.The configuration of the robot is very flexible, making a large range of experiments possible: Small peripherals can be designed and connected to the basic module, taking advantage of a versatile communication scheme.Due to its size, Khepera is also an optimal tool for experiments in collective behavior: 20 robots, as showed in the video, can freely run on a 2m2 area, which represent a tennis court for robots with a diameter of 40 cm.Finally a collective clustering behavior is presented, showing how very simple individual rules can generate an interesting collective work. During the experiment, several interesting interactions (like random object exchanges) have been observed. This collective experiment is under study and results will be published in the next future.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
