This paper presents an approach to implement the behaviors of multi-robots responding to user's input characters. The robots are appropriately displaced to express any input characters. Using our method, any user can easily and friendly control multirobots. The responses of the robots to the user's input are intuitive. We utilize the centroidal Voronoi algorithm and the continuoustime Lloyd algorithm, which have popularly been used for the optimal sensing coverage problems. Collision protection is considered to be applied for real robots. LED sensors are used to identify positions of multi-robots. Our approach is evaluated through experiments with five mobile robots. When a user draw alphabets, the robots are deployed correspondingly. By checking position errors, the feasibility of our method is validated.

The infrared camera is useful for night vision, detecting fire, measuring temperatures and detecting target in smoke. The price of the infrared cameras is rapidly decreased. Those reasons explain why infrared camera market is expanded and needs the infrared camera with small size, low weight and low power consumption (SWaP) for portability. Thermal Expert TM with low SwaP and highest resolution is developed by I3system as the business needs. The image of Thermal Expert is displayed with the smartphone. In this paper, Thermal Expert is presented with the performance compared with the infrared cameras of other suppliers in the world.
