goes into our formal design challenge of building a rube goldberg design

1. Introduction to Robotics
What are Robots

2. Overview
1. What is Mechanical Advantage (MA)
2. FORMULA for Mechanical Advantage
3. Designs for our Machines

3. What is Mechanical Advantage?
•Mechanical Advantage = The ratio of the
force produced by a machine to the force
applied to it

4. What is Mechanical Advantage?
The output force
divided by input
force
F = Force
MA = Mechanical
Advantage

5. DESIGNING RUBE GOLDBERG DEVICE
Teams of 2-3
Each Team gets 1 Board
Each Team member puts name on board w/Team Name
Each Team puts class (DAY AB Period Grade) on Board
First STEP, design actual components [simple machine(s)] on
board (each group needs markers)
Assign Students designated for glue gun
Safety goggles must be worn when building
Can bring materials from home :D

6. Rube Goldberg Design
• Design a device that will crack
an egg
• (device can be started by you
but must continue on its own)
• Can only use materials given
and/or recycled materials (no
electronics)
• SECOND STEP: Design device
on actual board, actual size,
before building, please use
marker
