- \chapter{Definition}
-
-
- In the initial design step we decided on combining two motion systems.
- One is the suspended cable system, this can easily cover the large board.
- However it lacks precision and this is where a small SCARA comes in to action.
- This arm provides speed and accuracy.
- And if the next bit of whiteboard is out of reach, the cable bot will move the arm to a new position.
-
- These two features are easy to define.
- Thus we have the SCARA and the cable system.
- So at this point we would just attach a marker to the arm and write on the board.
- However, now we cannot wipe text of the board.
- So another feature would be some toolchanger that can switch to the wiper.
- And, offcourse, later back to the marker, posibly with a different color.
-
-
- This brings us to the following features:
- \begin{itemize}
- \item SCARA
- \item Cable system
- \item Toolchange
- \item Wiper
- \end{itemize}
