In this research, we first investigated children's interests by questionnaires of some classroom for elementary school students. Results of questionnaires show that participants were divided into two groups who have interest in engineering (mechanism) and science (how animal and robot swim?). Then, an improved version of turtle-like robot, which has light sensors on board, was developed to fill child's interest for science and engineering. Child can lead this robot with intuitive feeling by using flashlight. This robot was also designed as line tracer along LED tube light.
