This paper presents a design of multi-purpose gadget control system for relief tasks including injection, hemostasis, and oxygenation. In order to utilize various gadgets, our system controls diverse motors and sensors. In case of an injection gadget, a sensor should find out if gadget would contact the skin or not. Another sensor could identify the full pressure to wound arm by hemostasis gadget. The limit sensor should make sure whether the oxygenation gadget fingers were closed. Based on these requirements for gadget sensors, the gadget controller should drive various motors such as air motor, BLDC motor, and linear motor for the proper gadget. The proposed gadget controller is cross platform which works the operational functions of injection, hemostats, and oxygenation in single unit.
