12. Mechanical Design¶
This week: Group project to design a machine that includes mechanism+actuation+automation+application
- Build the mechanical parts and operate it manually
- Document the group project and your individual contribution
Software¶
- Arduino IDE
- Fusion 360
Materials¶
- Clear 3mm Acrylic
- Draft Chipboard
- Various hardware (screws, various sizes)
- 3 stepper motors
- Arduino Uno board
- Board for Motor
Goal¶
Create a kit that could be used in a classroom. Specifically, a project that could be created together from a distance, and in FOUR(ish) Hours.
ReMix the Sphero into a classroom kit.
What is a Sphero?
What We Did¶
We divided the creation into three parts:
- Mechanical: Alethea
- Electronics: Janet
- Software: Justin
Mechanical Report: Create a case in Fusion 360 that contained motors, and boards.
Each level is the same design and can be used to:
-
attach to the next level using a screw and bolt,
-
mount motors on the edge of a level, and
-
mount the Arduino Board to a level
The total design will include two pieces:
-
The Base
-
The Motor Mount
In class learners can assemble the machine themselves, and lasercut: wheels, weights, and etc. Additionally, extra holes are added to the base to allow for including a pen/paint brush. And, multiple motors can be attached if learners would like to play, and explore further.
