Introducing the Stacker Robot Kit from ServoCity! This kit is great for both classroom applications and individual robotics enthusiasts. The Stacker wheeled robot kit is machined from 1/4” ABS plastic for strength and durability. The ABS framework also allows for easy drilling to accommodate custom attachments such as cameras, sensors, etc. The framework provides a large electronics compartment that stores the receiver, battery, and any additional added electronics. With 3” drive wheels and omni-directional movement, the Stacker travels well and is easy to maneuver. The Stacker Robot comes in kit form with assembly instructions, a parts list, and a 1:1 scale hardware key for easy assembly. The servos and radio control system are not included with the kit, and must be purchased separately. See the bottom of this page for ServoCity’s recommendations. Patented.
