Development of a Rescue Dummy with Damage Measurement by 3-axis Acceleration and Inner Pressure Sensing

Abstract

In the Rescue Robot Contest (ResCon), rescue dummies, which is called as ‘Damiyan’, are employed for competition evaluation. Rescue teams are required to rescue Damiyan gently and quickly. In addition, it is also required to identify the signs that are presented, and these are the evaluation items. Therefore, Damiyan needs various sensors to quantify “neck bending”, “pressure on body”, “posture” and “impact” as evaluation indicators of gentleness. In addition, the functions of “presenting color”, “uttering sound” and “presenting two-dimensional code” are implemented as the presentation of signs to be identified. To achieve this, we have developed a new Damiyan that incorporates the microprocessor BlueNinja as a core system for sensing, communication, and overall system control. In addition, an airtight body was manufactured to measure the grip strength, which measures the pressure on the body. The body is molded using a 3D printer and flexible filaments, and the surface is coated with a solvent to ensure airtightness. By using this new Damiyan, we achieved stable operation and reduction of management operations. In this report, details of the concept, the policy and the process of developing this newer Damiyan are described.
