Hexabot: Build a heavy duty six-legged robot!

Step 15 Tighten the bolts and repeat 3 previous steps

Now that everything is attached, you can tighten the bolts! Tighten them so that you can't spin the bolt by hand, but they spin easily with a wrench. Since we used lock nuts, they'll stay in position despite the constant movement of the joints. It's still a good idea to check them occasionally in case one has managed to work itself loose.

With the bolts tightened, one half of the robot is done. Complete the previous three steps for the other half of the robot. When that's done, the heavy-duty construction is completed, and we have something that looks like a robot!
