Recently, the study on small-sized reconnaissance robot has been progressed through grafting robot technology to military fields for minimizing the casualties. Especially, throwable robots have been focusing for their's efficiency in anti-terror operation. However, it is impossible to launch throwable robot to long range(approximately 100m) by hand. So we need another type of robots, so called launchable robots, which can launch farther and is more accurate by launcher. In this paper, we presented the process of developments of launchable robots('launchbot') which are available for remote launch from collection of user's opinions to field test. Based on the opinions of users, we established the goal of development, designed and manufactured the robots. Through the field test, we found that our launchable robot satisfied the performance requirements.

This paper presents the design concepts of a protector for a launch-reconnaissance robot that is to be deployed for data-collection in hazardous regions. The protector protects the reconnaissance robot inside from shock induced during the process of launch, flight, and landing. Since the outer shells of the protector are automatically opened wide by the unlocking mechanism during the landing stage, the reconnaissance robot can easily exit the protector and move around to carry out its mission. We carefully simulated a finite-element model of the protector with the robot and compared the results with the actual dynamic behavior of the system. Shock- response tests using a droptable showed that the proposed protector filled with silicon material successfully attenuated external shock.

This paper presents the development of a fracture-type protector for carrying a reconnaissance robot to a remote target area. Instead of a conventional unlocking mechanism, a separation method based on the fracture of assembled parts was implemented in the proposed lightweight protector in order to improve the feasibility for a real battlefield. Simulations using the finite element model of the protector and the robot were performed to verify the fracture under the given loading conditions, and shock experiments using a drop table were performed to calculate shock transmittance through the protector to the robot. Several field tests for a 100-m flight proved that the proposed scenario (launching, flying, landing, and separation) was achieved successfully.
