# Design space exploration |
|
|
|
|
|
|
|
## Introduction |
|
|
|
This document is a summary of the design space exploration. |
|
|
|
We are looking for ideas that can help us in our design of the whiteboard writer. |
|
|
|
This is looking for existing projects but also for different types of plotters. |
|
|
|
|
|
|
|
We are just searching on the internet. The summary is found in the next section. |

## Exploring |
|
|
|
|
|
|
|
### Image search |
|
|
|
Searching for `whiteboard writer robot` gives the following ideas: |
|
|
|
- [iboardbot (kickstarter)](https://www.kickstarter.com/projects/879074320/iboardbot-the-internet-controlled-whiteboard-robot) |
|
|
|
Plotter type robot. With Cartesian axis. But can also done with a different axis like [this](https://www.youtube.com/watch?v=5492ZjivAQ0), which shows some nice solution for the cabling. |
|
|
|
- [Scribit (kickstarter)](https://www.kickstarter.com/projects/1864378255/scribit-turn-your-wall-into-an-interactive-canvas) |
|
|
|
Kiting plotter robot. Suspended with two wires. Also this simple [example](https://www.youtube.com/watch?v=GgOi8WaNoIs), which clearly shows some design issues. |
|
|
|

|
|
|
Polar axis plotter robot. |
|
|
|
- [Robot Clock](https://www.youtube.com/watch?v=4QgeQAiSmM8) |
|
|
|
Simple clock with scissor arms. |
|
|
|

|
|
|
Articulating arm. With a lifting boom and rotation arm/link |
|
|
|
|
|
|
|
#### Observation. |
|
|
|
All systems are slow. |
|
|
|
Most have the problem of being 'heavy' and moving the arm quite some distance. |
|
|
|
The interesting one is definitely the kiting robot. It can be easily constructed but has still some design issues. |
|
|
|
It has de tendency to swing. |
|
|
|
Light models are quicker but in that case the oscillation of suspension wire becomes more dominant. |
