Re: Robotics beyond High School

In my senior year of high school, I felt that there was very little else I could learn from my team engineering wise. (I still learned a lot about managing and communicating) So when I got to the...

Re: Which Gearbox Should I Use?

It's great to see that your team wants to experiment in the offseason with different drive trains! My team tried building a 6 wheel WCD in the off season a few years ago and probably wont go back for...

Re: Confirmed New Districts for 2015?

Re: Questions about building a West Coast Drive with VersaChassis

Although the Toughbox Minis were direct drive, they were built to interface seamlessly with the new sheet metal frame on the KOP drive base. It looks like it would be a lot different to use them in a...

Re: Questions about building a West Coast Drive with VersaChassis

With the new products from VexPro and WCProducts, building a quality WCD can be done really quickly with little to no machining capabilities. Just to put it in some perspective, we used only a chop...

Re: Need help in deciding the configuration for an off season chassis prototype

I feel that has less to do with a square drive being "better" then a long drive and more of due to perimeter constraints, it was hard to acquire a ball being long. Thus many teams were forced to be...

Re: Need help in deciding the configuration for an off season chassis prototype

Honestly, I don't feel it really matters what the dimensions are for your offseason drive. However, I would make them so they fit all of the previous years rules to give you practice designing a...

West coast drives have a very specific type of gearbox, which has the gearbox's output shaft directly connected to the center wheel (if it is a 6wd). It also has chain/belt running through the center...

Re: New School / New Opportunity: FIRST or VEX?

In your situation, I would lean towards FRC over Vex. However, before I would choose one, I would bring a local team in a local team and see your students reaction (maybe try talking to 2848. They...
