This is a simple model for adding a pointer to the Dezibot robot. It allows the robot to be precisely positioned at a given angle, guaranteeing repeatability in motion experiments. The pointer needle itself consists of a thin, string-like structure that is tensioned by the robot's nylon stand-offs. It should be mounted as low as possible to minimise parallax error.

Three different models are available. V1 (thin) is a simple pointer and rather fragile. V2 (thick) supersedes V1 and increases the width of the pointer and reduces the overall height to improve flexibility. V3 (sturdy) aims to reduce the impact of the bottom-facing light sensor while retaining the needle point. V1 and V2 also include a crosshair to allow precise positioning of the robot in cardinal space.
