| Outline of Final Research Achievements |
This study is a communication system for mobile robots.I had gotten an idea that a method of suppressing wireless communication interference using the geometric nature of the triangle.Each receiver has limited reception area to 60 degrees or less.When communication interference occurs on a node, the node that has the widest angle of the triangle does not occurs interference.
Therefore, the node that has the widest angle of the triangle can be arbitrating communications with other nodes.I tried to develop the experimental equipment to confirm this idea.In order to detect the arrival direction of the signal using incident angle sensor.The incident angle is calculated based on the received signal strength.It waits the arrival of a communication signal pulse as a trigger.The experimental equipment operates as intended, such the incident angle calculation and the data reception.
