R/C LEGO� Dart Shooter Droid

In this project, I created a R/C LEGO® "Dart Shooter Droid" that combined the parts from components list below,

LEGO® Components
I divided LEGO® Components into four separate groups, Vertical Gearbox Support, Torso and Head, Left Arm, and Right Arm.
In addition I also provided the Instruction of the Target Bot. (Components for Target Bot, see Photo 5, are listed separately in Step 14.)
