Our team is 7592 from the space coast league in Florida. Our robot uses a cupping mechanism for the arm and also has driver centric mode which allows us to turn 360 degrees with our omni wheels. We 3D print are parts using fusion 360. I have a video about our robot maybe you guys could check it out and get some ideas.

We decided that one mechanism that turns in one motion would be faster than transferring between two separate mechanisms, and having to develop two extension mechanisms that were really fast as well as having a fast transfer between them would of been difficult.

I'm really impressed by how your mineral arm retraction system works. Is there a more in-depth explanation or picture on how you managed to get it to work so quickly? Our FTC team is entirely lost when it comes to mineral pick up because a lot of our team is new. Any guidance would be appreciated!

Our tips for a good mineral pickup is to prioritize speed with all of your design decisions, and usually that means make everything super light. You gotta think about the fastest way to get the minerals from point A to point B.

I'm not sure what you're asking for sure but the angle of the mineral arm is driven by sprocket and chain with two core hex motors, and the extension of the arm is driven by a dual spool attached onto a NeverRest 20 orbital motor.

Right now we are using a similar setup with two core hex motors running together, and we have approximately a 33:1 gear ratio. This works, and if needed allows us to completely rotate a 36" arm from the crater to the lander, but it is really slow and greatly impacts the amount of minerals we are able to deposit. Thanks!
