on the slapper, the slip gear is the 36t gear. would it also work to make the slip gear the the 84t instead (while keeping the same setup)?

22

Iā€™m 99% sure it wonā€™t work, not sure how to explain why exactly it doesnā€™t work but Iā€™ll try
If you cut off teeth from the 84T gear, whatā€™ll happen is that when you pull back the slapper it will reach the section with no teeth, then it will try to spin the opposite direction to launch the slapper, but when spinning the opposite direction the teeth will come in contact again and you get this situation where the slapper tries to launch, but the teeth of the 84T gear come in contact with the 36T gears again.

tldr no, you cannot make 84T the slip gear

Sorry for reviving an old topic, but does anyone know which file to open? I have looked, but canā€™t find a final assembly. thx.

24

Where is the .step file? I canā€™t seem to find it in the huge folder.

25

Same for me, iā€™m pretty new to inventor and am struggling with how to open the CAD file. If someone could walk me through I it would appreciate it very much

26

The fact that they used no pneumatics leaves so much opportunities tho

27

@vexreally Do you mind reupping just the step for these fine folks?

28

Sorry for the confusion everyone! I donā€™t know how the .STEP file was randomly deleted from the drive folder, but it has been reuploaded as of yesterday.

Our team built the chassis of this robot, and it is extremely slow. Why is it so fast in the video, what motor cartridges do you use, looks like green in the model. However, it only works out to 120 rpm. please advise.

30

I believe they are actually using blue cartridges, which should put the robot at a much quicker 360 rpm.

31

Thanks a lot. This should work great.

32

Hi, just curious what part is the black circle used for slapping the triball? Thanks

33

If I understand which part your are speaking of, they are call rubber bumpers. (Where to buy them)

35

quick question do you have the specs for the 3d printed parts

36

You can obtain them from the full robot assembly in the google drive.

37

Holey moley

That is a rediculously simple and effective robot
Good Job!!!

38

might make this for fun and give it so one of my sister teams

39

Take a peek at G4 before you do that.

Hello, can you kindly send me the .step file or show me where it is located on your shared folder?

Thanks,
