First Step

• Ball from D4 is the input of this system.
• The ball would drop from a height of 9 inches
  down a funnel
• Funnel would lead to the eraser tip of a pencil
• Through the transfer of energy, the ball would
  exert on the pencil idealistically 0.14715J and
  0.49N
• The amount of force can easily press the button
  on the robot as only 0.02 N is required

Jack in the Box

Step 2 Jack in the Box
Maureen
Cranking the handle The Lego Mindstorm will need
to exert a force of 1.96 N. Big Bird pops out
The force that the lid exerts from Big Bird
popping out is 1.18 N. This force will then be
transferred to step 3.
Where in space? Volume of toy 2197 cm3 Height
25cm(when lid popped up) Height of lid 11 cm
Step 3 initiated 14cm off ground
Jack in the Box

Lego Mindstorm
Mike

• Several design have been gone through
• Ideal voltage of Robot is 9V
• After calculations, the robot need to generate
  about 1.18N on the arm to move the handle.
• To have the robot successfully touched the
  handle, one must figure the height of the jack in
  the box handle, which is
• The robot also has a sensor in front, so that it
  can stop as soon as it hits the jack in the box.
• The arm also needs to be extended 10cm outward
  from the front of the car and it is situated on
  its right side in order to successfully push the
  handle.
• Tank mechanism is also used so that it drives
  slowly and steadily towards its destination.
• The program tank.cc is going to be reworked in
  order to accommodate the modifications for the
  situation
• Only one sensor is added for the stopping
  mechanism of the robot.

Different prototypes
- No need for cuteness!!!!!!
-Too hard to built -No need for three wheels -No
need for two arms

• Easy to built
• Sensors!!!!
• Can achieve what has to be achieved effectively

Step 3 and 4
The 3rd step in our groups part of the Goldberg
device is a combination of dominos and a pendulum
swing. These steps will continue the transfer of
energy through our space with a step that
includes a biomimetics design.   Dominos Dominos
will first be triggered by the swinging motion of
the jack in the boxs lid. The dominoes will be
placed on a platform that raises them to be
flush with the top of the jack in the box top.
The object of the dominos is mainly to transfer
kinetic motion through means of stored
gravitational potential energy, from one side of
our given space to the other. The raised dominos
will incorporate a biomimetics wave design in
their track. Once the last domino has been
triggered, it will transfer its motion, into
knocking the pendulums ball off of a
stand.   Pendulum The pendulum will be raised to
a height of x to match the height of the domino
track. The pendulum ball will be set ontop of a
lip that is slightly higher than its swinging
radius. Once the pendulum is engaged by the
domino and set into movement, it will transfer
kinetic energy though means of stored
gravitational potential energy. The calculation
we had to do to determine the energy we would
have according to gravitational potential is Ek
mgh. Kinetic energy of the pendulum is noted as
________. The ball will then strike a ball at the
top of a ramp, setting forth the next team (11s
devices.
