The position of the brick makes it hard to start the programs from the brick. Students often position the brick in the same manner when have a class, where they can build on their own, without thinking about the consequences. It is good that this is a robot that is build based on instructions and have the same problem. This will make them pay more attention to the issue. If they ask on their own to change the position of the brick, let them.
At the end of the lesson point out the issue infront of the whole group and explain to them that this position of the brick should be avoided and the brick should always be positioned in such a way that will allow us to have an easy access to it's display and buttons.
