Simulador de Robos

Local: domingo em Araranguá
Instalado no linux RoboMind - simulador de robos para ensino de programação. A instalação deu certo mas não rodou por não achar o java (erro do Wine). Baixado da Sun a runtime do java 6, instalado corretamente mesmo assim o simulador não funcionou.
Instalado e testado o simulador Rossum, que simula um robo programado em Java. verificar.
