SUMMARY:

The usage of robotics as a supporting tool to educational activities has gained traction with the popularization of both consumer-grade 3D printers and the promotion of events such as the Robocup Junior Rescue (RCJ). To compete in such contest, students need to design and make their own robots, which should be able to solving rescue tasks that most often require picking up a ball (or a similar object) on some irregular arena ground. We have made studies using as basis a existing platform, whose construction steps are available in the Interenet, in order to verify gains achieved by students when a ready claw design for picking the ball up is offered to students. We notice that device is to be constructed by the students themselves, however with guiding steps available on the Web. This paper analyzes different claw designs, both active (a design that uses a motor) and passive (a design that does not use a motor) in order to evaluate the abilities and capabilities of each design. Active designs showed to be better, however, of hard implementation by the students (mainly the level task). Hence, we propose a passive design with comparable effectiveness to the active design in order to reduce the complexity of robot construction. Experiments show that the approach reduces failure points and facilitates the process of teaching a lay-student on building a robot capable of surpassing the challenges proposed by the rescue line challenge from OBR at its fundamental level one. We have made experiments in schools to validate the applicability of this new design, which also accounted for verifying if the developed tool is in accordance with the abilities of curricular bases, and if this kind of support would not compromise the students learning, which is the main goal of educational robotics.
