Conclus˜ao e trabalho futuro
Ao longo deste projeto desenvolveu-se um robˆo de baixo custo (figuraA.1), apresentando o m´odulo dos motores (j´a com rodas) o custo de 60e e a placa PCB o custo de 1,5e. Tal como se tinha idealizado, a programa¸c˜ao deste robˆo ´e poss´ıvel em trˆes linguagens de programa¸c˜ao distintas, nomeadamente, CircuitPython, MakeCode e Arduino. Assim sendo, os objetivos propostos foram alcan¸cados com sucesso.
Fornecemos assim, um robˆo alternativo que se destaca pela programa¸c˜ao simplista e variada aliada ao baixo custo e hardware de qualidade. Assim, os jovens iniciantes nesta ´area podem sentir uma maior acessibilidade em termos de programa¸c˜ao e uma motiva¸c˜ao extra para evoluir.
Em termos futuros, pretende-se dar continuidade ao desenvolvimento deste software de forma a complement´a-lo e aperfei¸co´a-lo. Para tal, idealiza-se o desenvolvimento de m´odulos de navega¸c˜ao, m´odulos de MakeCode e bibliotecas em arduino, de modo a estabelecer uma maior utilidade e aplicabilidade pr´atica.
