Great arm design! The beach bots did amazing with that style arm.

What motor we're using is still a top secret, but when we'll have it ready I promise to upload a photo of it. Im sure you'll be impressed

my guess is a window motor or possibly FP with the right ratio setup. It looks like a 50ish tooth sprocket for maybe a 5 to 1 ratio. Our ratio is a little higher with the window motor, which moves our arm with no strain on the motor. When we had a 4 to 1, torquewise was fine, but the speed was just a little too quick and jerky.
