Goals
Core goal: Clean the blackboard quickly and effectively, leaving no dead corners.
Secondary goals:
1. Provide a function to save the blackboard content before erasing, which can be linked with the projector to recall the previously erased content.
2. Remote control through a mobile app.
3. Provide a dust removal solution to prevent dust pollution from affecting the health of users. (May be the most important secondary goal)
4. If you decide to have projection capabilities, you may be able to combine voice recognition and natural language processing functions to record some important words (using ready-made APIs, such as Google Speech-to-Text), or even connect with chat AI such as GPT or Deepseek to provide AI assistant services instantly through oral dictation when needed. (This is relatively simple in theory. After all, it is a purely procedural job and does not even require much debugging.)

Could be used for finding the optimal cleaning path without being too computationally intensive.
TIANLEI WANG, NANLIN TAN, et al; "Global-Equivalent Sliding Mode Control Method for Bridge Crane"
Could be used for controller if we decide to go the direction of cranes. Instead of wind resistance we can use the resistance of the cleaner against the blackboard. Unsure if still applicable when using two wires to hang something from, but should be fine.

Interesting way to do locomotion on the top of the blackboard. Depending on execution might be widely usable, also over handles like in the lecture hall in Gemini-south.
Patent automatic blackboard cleaner: https://patents.google.com/patent/US3731335A/en
Spans the entire height of the board, not very adjustable.
Y. A. Maruthi 1 & S. Ramprasad 1 & N. Lakshmana Das 2; Trace Elemental Characterization of Chalk Dust and Their Associated Health Risk Assessment
Reason besides labor saving to make the robot: might prevent some chalk from going into the air. Would need scientifically supported better method of cleaning then.

The design of a vertical column-shaped blackboard-erasing robot was demonstrated, which uses roller felt for cleaning and a dust collection module that uses static electricity to prevent dust from flyiny around.

This is a design that divides the blackboard into four different areas, and has the function of connecting and controlling via mobile phone Bluetooth. Based on Arduino, it can be used as a reference.

This is a six-rod mechanism designed to imitate car wipers. Considering the long-standing successful design of car wipers, referring to this solution for improvement may make our design more eye-catching.
