The instructions are clear and easy to build. Only problem it had was the battery not being able to stay in position for it to work properly. So I used elastic bands to keep it in place. Without the plastic bands, it was stopping and going.

Funciona! É fácil de montar e funciona muito bem - o robô inclusive é bem rapidinho! Fez o maior sucesso aqui em casa e minha filha levou para a aula de ciências da escola e foi a sensação do dia! Alunos e professores adoraram! Vale muito a pena!
