Robotic Arm Edge
While it appears to be something from a sci-fi movie, this technical-looking robotic arm is surprisingly simple to assemble. Encased within yellow and black plastic, the gears enable motorized wrist movement of 120 degrees, elbow movement of 300 degrees, base rotation of 270 degrees, and the ability to lift up to 100 grams of weight up to a foot. The gripper "hand" also features an LED light to locate objects in the dark. The controller holds five switches for manipulating the robotic arm, and a safety gear audible indicator helps prevent potential gear breakage while experimenters are testing its limits. Instructions are completely pictorial, with clear drawings and pieces numbered for assembly. So what could you do with an extra arm?
The RobotiKits from OWI have no comparison. For flawless assembly: 5 stars. For clarity of instructions: 5 stars. For durability of constructed robots: 5 stars. For robots that actually work as advertised: 5 stars. Let's face it - not all kits turn out as well as they are supposed to, but you can count on these kits going together and functioning with the perfection of precision engineered components. All kits come with a pre-assembled circuit board. Most components are made from plastic and either snap together, or hold in place with the provided screws. Some kits may require some additional tools listed below. What sort of knowledge will be gleaned while enjoying these fun kits? Gear structure, battery wiring, motor principles, electronic circuits, circuit block diagrams, and comprehending assembly instructions. Try one today! CHOKING HAZARD (1). Not <3yrs.
