Simple Machines "think, do, test" packet

Some cool robots

Think: yesterday we made the pendulum, and tested it twice, and it failed because the actual pendulum would swing side to side, so today we are going to double up the middle part to give it stability to not swing side to side, and possibly add weight to the wheel if there is enough time. I would also like to adjust the force that I put when pushing on the pendulum.

Yesterday, the modifications that we made were pretty successful. I would say that with the modifications our pendulum knocks down the blocks about 3/5 times. I would obviously like to improve it so that it works every time. I think that if we raised it up higher, that would give it more kinetic energy, and probably knock the blocks over every time.

What we did to make our pendulum accomplish an 80% success rate, is we modified our pendulum to stay still at the base more. We also put some ski type things on the bottom to improve stability even more. Another thing that we did was we double wheeled our knocker-over. We also made broader platforms. We could have gotten 100% but we got unlucky in my opinion

Yesterday we finished our pendulum with an 80% success rate by making modifications to make our pendulum heavier, and now we are moving onto the pulley system for the first time. Description for pulley system: we must create a pulley system/elevator that can life/transport 3 blocks 3 meters high, that needs to have a container or platform to hold the blocks, and also has to have a crank handle.

New Week

On Friday, we got more of our pulley complete, but it was not able to hold the blocks, so we are making modifications today to make it be able to hold the blocks. One of the modifications we are going to try to get done today is to add platforms onto the wheels to make it be able to hold the blocks. If we have the time to also modify our pulley to finish up with a lever system, that would be optimal if time allows.

Yesterday, I built one of the platforms for the pulley to be able to pull the blocks into the places that they need to be. I know that today I need to build the other platform, and quickly. I am hoping to build the lever also today, so. I can get to filling in my packet, and maybe starting on the assembly of the Standard Drive Base
