Build Systems Review
There are many available build systems for FTC and we have used four: Tetrix, Rev, Actobotics, Gobilda.
Here is our review:
Underrated. A lot of teams say it is really bad but it is easy to learn for new teams with little hardware experience. Our first robot was made in Tetrix.
The current favorite. Our robot drive train is built from this interesting system. How it works is very unique because instead of screwing things together the normal way, you slide pieces together and tighten them. This makes for a clean design but also is very annoying when you have to disconnect an entire piece just to add another mechanism inside because you can only access the attaching part by disconnecting the whole thing (Except with t nuts which are less stable though)
The only Actobotics thing we used was for our linear extender and it is compatible with Rev. The channel is very strong and sturdy and we are likely going to purchase the Actobotics kit in the future.
Our linear actuator is GoBilda and it is super reliable. We have used the same actuator for the whole season and it still works great. We will also probably purchase the kit for next year.
Actobotics and Gobilda in particular are very generous and give really good discounts to teams. Rev and Tetrix are less generous and Tetrix has almost no community involvement as far as we have seen.
In the future we predict a lot of teams moving towards Gobilda and Actobotics but Rev and Tetrix will still be useful.
