Objective
2020 |
Raise a flag from the bottom to the top of a 1.0 m flagpole. |
| Purpose | To
demonstrate scientific skills, creativity, teamwork, and have a funtastic time.
|
| Participants | Teams
of three to six. |
| Materials | Supplied
by the Team. The Rube Goldberg Machine will be built and tested at school. |
| Rules | The
machine must occupy a maximum space of 2.00 m x 4.00 m, and points will
be awarded for making full use of the specified area.
Two attempts will be
allowed to attain the objective. Both runs will be marked. |
| Judging | - 1
point for each event or action
- 5 points for succesfully achieving the
Objective.
- 5 points for aesthetic appeal
- 5 points for creativity.
-
1 point for each different principle of physics employed
- -5 points
for each assistance beyond the first.
Machines will be judged on their use of recycled materials.
10 Points will be deducted from the final team score if a visible footprint of their presence is still detectable 20 minutes after the end of the competetion. Clean up your mess!
If a part of the machine fails,
the team can restart it once without penalty.
If subsequent restarts are required,
one point is lost per restart.

| The
Cog | One of the best examples of a Rube Goldberg machine is the Honda
Cog Commercial. Use your favourite search engine to find and view it. |

| Safety |
Safety Considerations for Rube Goldberg.
- Machine Base – The machine's support or base is stable enough to:
- Safely support the machine.
- Prevent structure movement.
- Electrical
- All exposed electrical connections are guarded or insulated to prevent contact.
- Electrical power cords are free from hazards, such as abrasion, fraying and pinching.
- The maximum voltage used is 12V.
- Wet cell batteries such as car or boat batteries are not allowed.
- Rotating Parts.
- There are no exposed rotating shafts, belts, reciprocating parts or other mechanisms that could cause injury on contact.
- Protective guards are installed to protect operators and spectators from accidental contact with projecting or flying parts.
- Flying objects – balls, other objects – do not have enough momentum to escape the machine's confines and injure operators or spectators.
- Stationary items that project from the machine and that might cause accidental injury are shielded.
- Chemicals/Liquids/gasses
- There are no chemicals used that might injure operators or spectators.
- There are no open flames used, covered or uncovered.
- An uncontrolled release of any chemical is not possible.
- Liquids cannot accidentally contact electrical components of the machine.
