The arms of this little robot articulate at both the shoulder and elbows. You can use a 2x2 tile with a pin (part 2460) underneath the 2x2x2 65 degree slope to create a turning waist on the robot. This piece is included in the total inventory here, but is not in the inventory in the LDD file. This build uses two spare parts that come with the set upon which this build is based.
