Remote robotics laboratories have been successfully used for engineering education. However, few of them use mobile robots to to teach computer science. This article describes a mobile robot Control and Programming Environment (CPE) and its pedagogical applications. The system comprises a remote laboratory for robotics, an online programming tool, and a virtual learning environment. It allows experiments with a mobile robot to be carried out, tested and validated remotely, using a simple graphic interface via web browser, without additional software installation on the user's computer. Students can control and manipulate the robot with simple commands without worrying about hardware details or use C/C++ programming language to develop complex programs. The robot has been built with inexpensive components and has sensors that enable its use in several experiments. CPE can be used in contextualized teaching in various subjects of computer science, both in class and at distance. A practical application of the whole system using CPE, introducing programming concepts, is also described in this paper. The initial assessment of the environment as an educational tool shows high levels of interest among our students, an improvement in their academic scores, and potential for application in the context of computing education, when properly introduced as a learning tool.
