After building Joebot’s torso, legs, shoulders, and right arm, he’d sure look silly without a matching left arm.

Step 26: The left arm is, of course, much the same as the right, beginning with a grey brick 1x1 with headlight, and a grey brick 1x1 with studs on four sides.

Step 27: Connect the two pieces with a blue 1x2 tile with grille.

Step 28: On one of the studs sticking out to the side, attach a 1x4 hinge plate.

Step 29: Add the black decorative 1x2 tile and a transparent blue 1x1 plate. Attach a grey 1x1 plate with horizontal clip for Joebot’s hand.

Step 30: Attach the arm to the shoulder by inserting the t-bar into the “headlight,” again being careful not to shove the t-bar all the way in.

Step 31: And now you have a robot with two arms and legs. He’s almost done ...

You can’t have a headless robot! Dude needs a head!
