2-1. Install the Ball Roller

Before we can start building GrabbE, we’ve gotta take GabbE apart first. Don't worry, it’s all part of the plan!

Start by popping off the mouth. Then grab your screwdriver and remove the nut and bolt holding the left eyeball gear in place. Slide the right eyeball socket off the servo motor to finish clearing the base.

Now for the fun part, let’s add the ball roller underneath so GrabbE can glide like a pro! Stick a bolt through the hole at the very top center of your base, just above where the eye gears go. From underneath, screw the ball roller onto the bolt nice and tight.

Pro Tip: Use your flathead screwdriver to lock it in snug. No wobbles allowed!
