mobile goal lifts

We’ve always used our DR4B to pick up mobile goals. Our first bot was a 6 motor 1:5 that was all steel. And our newer bot is a 4 motor 1:7 all aluminum. Both are external stackers and it may not be the best way to pick them up but hey it works.

What else can launch a 90 kg projectile 300 meters?
