The robot was made from scrap wood and a few pieces from an old K’Nex set. It’s similar in style to Mr. Tipsy from Raivan as shown here. Differences in this version include shape, size, number of parts and mid-point rotation.

As for motion, the head, hands, feet and hips spin. The arms and legs have two rotating joints. See animation my kids put together for some cool robot dance moves.

Step 1: Tools/Materials

Tools:

Band Saw
Table Saw
Drill Press
¼” Drill Bit
Sander
Hammer

Materials:

1x4 x 24”
2x4 x 8”
¼” Dowel x 14”

Step 2: You Will Be Building to This Drawing

Note that the parts are color coded for easy reference.

Step 3: Body

The body was made from a 4" long 2x4. Drill the holes at the locations shown. Note that the drawing shows through holes for simplicity. These four holes only need to be 1/2" deep from the sides.

Step 4: Hips

Cut the Hip as shown. I used the round end side of a 2x4. Again, the holes only need to be 1/2" deep.

Step 5: Head

I used the excess from the 2x4 for the head. You might want to pre-drill the holes for the facial features at this point.

Step 6: Pins for Arm, Leg, Hip and Head

Cut 1/4" dowel to the lengths shown.

Step 7: Arm Assembly

See Video of the Arm and Leg Build here:

Step 8: Arm Parts

Cut the 1x4 into 1.5” strips to be used for the legs and arms. Cut the parts as shown. I used a table saw for the Arm1 slot. I assume a router table would have been easier/better way to make this cut. I used a band saw for Arm2 and the Hand. The holes were drilled with a drill press. A sander was used for the chamfers.
