ABSTRACT
Due to the growing demand for natural Human Machine Interfaces and robot intuitive programming platforms, a robotic system that allows users to control industrial robots using arm gestures and postures was proposed. Most of industrial robots are still programmed using the typical teaching process, through the use of the robot teach pendant. In this paper is proposed an accelerometer-based system to control an industrial robot using two low-cost and small 2-axis wireless accelerometers. These accelerometers are attached to the human arms, capturing its behavior (gestures and postures). When compared with other common input devices, especially the teach pendant, this approach using accelerometers are more intuitive and easy to work, besides offering the possibility to control a robot by wireless means. Using this system, a non-expert robot programmer can control a robot quickly and in a natural way. The low price and short set-up time are other advantages of the system. Nevertheless, the reliability of the system is an important limitation to consider. Future work will build upon the improvement of the average of correctly recognized gestures. The use of more accelerometers attached to the arms is another possibility.
