Ratcheting Sprocket

My final report is a PDF document. I am not sure it went through, so I will also leave a copy of the report here. This is not my final submission, as my final one is uploaded directly. I am in the VRC High School Division.   Ratchets are an important part of robotics: they allow you to have multiple mechanisms run by a single motor. This has become increasingly important over the years with a smaller motor limit of eight being implemented. What I set out to do was to create an easy-to-implement ratchet for teams to use on their robot. I did this by combining a ratchet with an already well-used part: the sprocket. The sprocket is used commonly to link two different mechanisms together, which is also a ratchet's most common use: to share two mechanisms to the same motor. My new part will allow teams to easily and effectively implement a ratchet into their robot.

I like that you've made a compact rachet that integrates well with existing vex parts. Nice job!

Thanks for your kind words!

I really like this. Good job ianbrueggeman. I feel this could be very helpful with a lot of robots not only now, but in the future as well. I see it is also seems pretty easy and would be cheap for VEX to make and distribute. It is overall a great part and I can't wait to see all the robots with it installed.
