Rube Goldberg Take 2
Draw and explain a
Rube Goldberg design that will include the following components:
·
Digital
·
Motor
·
Relay
·
Opamp
·
Temperature sensor
·
LED
The setup should be
considered to last 30 seconds. Make sure to include enough photos, videos, and
explanations for each transition or step. Explain your circuits. Put at least 2
issues/problems/struggles you faced during the project.
Our Rube Goldberg machine is based on a step by step process, The process starts with heating the temperature sensor. After the sensor is hot enough, voltage will pass through and then trigger the relay switch. The relay will power an LED to show that the system has power. The 7 segment display is in series with the LED and receives power at the same time. When both are activated the display is connected to an OR gate which is connected to a motor. Whenever the display shows numbers 4-9 the motor will power and pull a string that is connected to a mousetrap. After the mouse trap is pulled enough, it will activate and send a ping pong ball flying in the air. Videos and pictures of our circuit are below.
For our Rube Goldberg machine we faced many problems throughout the week. Our first and largest problem was with our temperature sensor. Our sensor was burnt and was not allowing correct voltages through. We were not aware of the issue and it ultimately ended up having us take longer and not being able to present to the class. However, after we changed the temperature sensor out for a new one, our circuit was able to run properly. Another issue that my group faced through the week was connecting all of the components and having them work. We were able to have the seven segment display and OR gate work properly but struggled to think of where to place the relay and temperature sensor. Eventually we worked it out and were able to have a successful Rube Goldberg machine.

This is our Rube Goldberg circuitry.
This is our entire set up with the circuit and a mouse trap to the side.
This video explains our Rube Goldberg machine and shows it working in action.

The idea of mouse trap is creative and interesting. Good job! Congratulations! btw we also met the problem about temperature sensor before, it's easy to be burnt....
ReplyDeleteYeah, they can be tricky! Thank you!
ReplyDeleteLooks great. I wish it worked on the demo day.
