Automatisation process

To make the robot drive as easy as possible, the whole stair climbing part  was automated. This was carried out by measuring the time it took to  execute all the commands to climb one stair. This seemed to work fine at  first, but unfortunately it has one major drawback: the battery. When the  robot moves and even when it awaits a command, the battery drains. This  loss in tension results in a loss in power and subsequently in a loss of  torque. As a consequence the robot will take longer performing every  command. Because the required time does not match the preliminary  defined time anymore, the robot may fail and fall of the stairs which is not  ideal. However a solution exists. By mounting a proximity sensor to the  bottom and to the front of the robot the exact position could be known.  Replacing the timings by distances would solve the problem, making the  automated driving function almost fail proof. Unfortunately the constraint  of time made it impossible to execute this modification, however it is  recommended.
