Abstract:
The modern world with lack of availability of an effective learning platform for students
who are tired of traditional learning techniques. In the present day, basic mathematics is
the most valuable fact for primary level students to improve their problem-solving skills.
This study is carried out to develop a cost-effective open-source robot with a rewarding
system for the children of the age group between five and ten years. The open-source
robot chassis designed with computer-aided designing which can print by using 3D
printing technology. In this research, a Java-based library is developed to communicate
with the microcontroller of the robot and the hardware of the smartphones. And also,
there is another problem that they have to spend more strive to build a robot as it is not a
work that can be done in less time with a low budget. Throughout this study, present
solutions such as Cosmo, Poppy, Q.bo-one are considered to gather information. But
these robots are costly and also lack of opportunities to use for education purposes and
that robots need external hardware sensors. But in the modern world, most people own a
smartphone and it contains the above hardware (Processor unit, Sensors.). If can reuse
that mobile phone hardware as robot hardware it will much cost-effective. Researchers
decided to combine three ideas of open-source hardware/software, 3D printing
technology, and reuse mobile phone hardware. As the final solution researchers build an
open-source robotic platform with reusing mobile phone hardware combining the android
library and finally they build an educational robot to evaluate the platform. Furthermore,
researchers analyse the effectiveness of the built educational robot by providing a
questionnaire to the students (age group 5-10 years) & getting feedback from them.
Researchers plan to use PCB designs as hardware circuits into one platform which
reduces the circuit space and commercialization of the product in the future.
