U Design an MBot Pen holder
The Problem: Can you create a product that can hold a pen for our MBots that can combine coding and art?
Start by sketching out some designs on a piece of paper take into mind the features you see below
​
Features:
1. Fit - It must fit onto the Mbot
2. Size - It needs to hold a felt or pen
3. Measurement - It must be fastened to the MBot in some way to draw when it is moving
4. Flex- It must be flexible to accommodate for various size pens
5. Strength - It needs to be strong as it will be used all day long with multiple classes
​
What is the diameter of these holes?
How long is this?
How much room do you have before you hit this sensor?
How far out do you go?
To create this design below is a completed example of a pen holder. You can view this example but must come up with your own design. You will also notice near the pen holder there is a pin holder that attaches to the back of the robot for balloon popping, perhaps you can improve on that design as well!
Have your teacher print the model (it should be a short print) then place the prototype on your MBot for testing to see if it works. If not return to your prototyping to build a new design.
