Week 5 - Quiz 5

The class you've all been waiting for: how stuff moves.  We'll cover some of the math of actuation, as well as an overview of the different parts you can use to move things around.  I'll get into how each different system works so that you can understand the theory behind selecting things.  Because movement is at the core of mechanical engineering, we have to build up to this!

1. Introduction to motion
   1. The math of motion
2. Gearing systems
   1. Spurs
   2. Bevels
   3. Worms
   4. Differential
   5. Transmissions
   6. Clutches
3. Actuation
   1. Linear actuation
      1. Solenoids
      2. Pneumatics/hydraulics
      3. Electrical linear actuators
   2. Rotary actuation
      1. Standard DC motors
      2. Servos 
      3. Steppers

Class 5 Video:

In another speedy overview, we'll discuss some of the knowledge necessary to design fluid systems.  Will include anecdotes from my background in cocktail robotics and practical design criteria to help you build your own piping, pumping, and valving systems.

1. Definition of a ‘fluid’
2. Piping
3. Pressure vessel design
4. Pumping systems
5. Valves

Class 4 Video:

This course will cover methods of conventional fabrication and will include a list of twelve essential tools to own.  Plus, we'll talk about how to use your machine shop (or how to select a good one).

1. Types of fabrication
   1. Additive
   2. Subtractive
      1. Cutting
      2. Grinding
      3. Others
   3. Welding
2. Will’s List of Twelve Tools To Own
3. How to design for the machine shop
