This term we are doing a project based upon what you can create with your ideas. Me and a couple of my friends (Shannon Fury and Mitch Bickett) decided to make a Rube Goldberg Machine. For this we needed to bring some stuff from our homes and also some stuff from the makers space. For the first design session we did pretty well but the structure was quite basic.
This was the first sessions part of the Rube Goldberg machine. This consists of pretty much an Inclined plane which is the only simple machine in it. The materials we used were Dominoes, a marble and Lego robot track.
For the second and third session of our project we changed our Rube Goldberg a heap, we got rid of the Lego track and put in hot wheels track going down the side of the chairs. We also put in a pipe which the ball would hit and roll down to knock down more dominoes. There was also a few other things we added in like a funnel taped to a tube.
Here is our Funnel and Tube at the start of our Rube Goldberg Machine. The ball is meant to go down funnel into a Tube and jump up into a pipe. In the third session We changed the tube and the funnel to make the ball go into the pipe exactly instead of jumping in because only 1 in 10 of those jumps worked.
This part of our machine is the middle of it all. The point is for the ball to roll down the funnel hit the next dominoes and knock the ball off the table which was connected to a piece of string that at the other end was attached to a Popsicle stick which had a ball behind. Then the ball would go down the track. The materials we used for this part of the machine were a pipe, dominoes, a marble, string and a Popsicle stick. The Simple machines on this part were an Inclined Plane, I think a Lever or a Pulley and a Wedge.
Here is our Hot Wheels track that goes down the table (with a few cards to make sure it doesn’t fall off), and then go into a bucket. We put a few Jenga blocks underneath the bucket so when the ball hits the bucket it will fall over and knock more blocks. This part of the Rube Goldberg machine has an Inclined Plane and I think it involved a Lever as well.
Here is 3 videos of the machine 2 of them don’t work and the other does.
For the fourth and fifth session Shannon, Mitch and I decided to make some changes like to add some stuff in that we came up with. Underneath is a video of me and James’ machine.
The plan was to make a some stuff from me and James’ house to bring in like Hot wheels tracks to make the ball roll down. Underneath is a few descriptions and explanations for the tweaks and changes we made.
We changed this bit of the project a bit to benefit the new part of the machine so when the ball falls down it knocks the chupa chup box onto Jenga blocks set up as dominoes to knock over a Jenga block with string on it which pulls a marble off the table which starts the next part of the project.
This part is a new bit which I kind of made off the first part of my Rube Goldberg machine I made at my house. When the marble falls off from the Jenga block with string on it pulls a domino off the track which is holding a ball behind it. Once the domino has fallen off the marble flows down the track knocking a Jenga block off the track and off the table that is attached to a domino pulling more dominoes. When the last domino has been pulled off it pulls a domino off the track on the other side of it’s string allowing a ball to pass through knock a domino with string off the track while on the other end of the string the final domino gets pulled off with the ball going down the track into a funnel. This part consists of Inclined Planes and I think levers and pulleys.
Here is a video of how it worked out.
For sessions six to ten we made some new adjustments like the tunnel, the lever and the goal pipe. Underneath is a description of the new parts of our RGM (Rube Goldberg Machine).
The first part of this bit of our RGM is where a ball goes down the funnel and into a pipe which leads n down to hot wheels track with Jenga blocks on the side to make sure the ball goes fast but then make sure it doesn’t hop out the side. The second part is at the end of the first part, it is where the ball will hit the K’nex piece holding the marble. The K’nex piece will then fall off the track leaving the marble to go down and knock a Jenga Block into a Lever with the force of the ball to knock it down.
This part isn’t that good footage because of the sun light but the whole point of this part continues on. After the marble the part before knock into the Jenga block giving it the force to push the lever there will be a domino at the top of the table right next to the other side of the lever which will knock the domino over knocking more dominoes (We ended up not using the Hot Wheels track that is this picture). We found out that a little domino could not knock a Jenga block unless it had more force and the lever at the start of this part was to light to knock a Jenga block so we decided to tape 2 marbles to the top of a little domino that would be strong enough to knock a Jenga Block. The Jenga block would then knock a Pulley filled with 5 or 6 marbles would then pull and lead on to the next part of the RGM.
This part of the RGM was pretty short. After the Pulley pulled the marbles off the table there was a marble resting on top of the rod (with a little help from some tape) the pulley this end of the pulley would pull a little bit just enough to make the marble fall down the pipe.
Once the marble has gone down the pipe it goes across a bridge of Hot Wheels track, into a pipe and then finally into the goal knocking the goalie into the goal with the ball.
This machine took 209 tries to make it work.
