microcontroller.
Introduction - This prototype will be used as didactic material to learn and to know about robotics. Emphasis is placed on previous knowledge such as programming. Subsequently, a didactic model will be used which is projective, that is, in order to carry out an idea applied by the students and investigated autonomously, with only the help of the teacher for its proper execution.
The design was made in a 3D CAD modeling software, programs that allowed dimensioning the mechanical structure. The electronic control was carried out through an ATMEGA 328P microcontroller, which makes it possible to read the status of the sensors, in this case flexo resistors, while generating the signals to control the servomotors responsible for the movement.
So in this work, it is proposed the develot of a robotic hand prototype. The design will be done in a 3D CAD software for the modeling of the parts, then exported to a 3D printing software, thus making accessible and interactive the contact of students with the programming of the robotic hand by means of an ATMEGA 328P microcontroller. In this way, it is expected to increase the educational motivation of skills and knowledge of the students of the Technological University of Tlaxcala in the area of technologies with different projects related to robotics.
The final version was built with available materials, resulting in the prototype of the robotic hand as a didactic model. It can be used as a motivational tool for learning microcontroller programming. A pilot test was conducted at the Technological University of Tlaxcala. We worked with 5 eighth semester students, together with the head teacher of the Integrator course.
Methodology The robotic hand prototype as a didactic model is to teach in an interactive way and make students have motivation to acquire knowledge of the branches of automation, mathematics, analog components, to name a few, which is a support to get into new technologies, making didactic knowledge. As a didactic model, a programming of a binary counting, supported by the robotic hand, was made.
The implementation was accompanied by several classroom plans and didactic aids, whose purpose consisted of the theoretical explanation of the concepts that were worked on and the application of these on the robotic hand. As well as a bit counting sequence. It is important to note that, before implementing the didactic prototype in the classroom, the students acquired previous knowledge about electronic components and also about programming. In contrast; as for the teacher, in order to implement the prototype.
A. Didactic model and projective model According to the objective of this study, which is to create the didactic model based on an automated hand, the research method used is Research, development and execution of this model.
Consequently, the robotic hand executed a sequence of bits, programmed by the students, thus evidencing learning in the area of robotics.
