This is the Micro Gripper Kit A, an amazing robotics kit perfect for small - scale robotics projects. It's designed to work with any sub - micro size Hitec servo. Assembly is a breeze, requiring only a Phillips Head Screwdriver. The gripper can open up to 2.75' wide at maximum. It has a 1.7' long body and a 1.3' wide servo housing body. There are three 6 - 32 mounting through - holes along the servo housing edges. Actobotics is a great robotics building system with extruded aluminum channels, gears, precision shafts, and ball bearings. With two standardized hole patterns, most Actobotics components can be easily connected. This wide range of components makes it possible to build complex electromechanical prototypes or finished projects. Note: This kit doesn't include a servo. Check the 'Recommended Products' section for sub - micro size servo options. Features: Opening Width - 2.75' (69.85mm), Mounting Hole ID - 0.1' (3.5mm). Documents: Product Video.

Using the Micro Gripper Kit A is easy. First, gather a Phillips Head Screwdriver as it's all you need for assembly. Then, connect the kit to any sub - micro size Hitec servo. Once assembled, you can start using it for your small robotics projects. Remember, this kit doesn't come with a servo, so pick one from the recommended products. When using the gripper, don't force it to open wider than 2.75'. For maintenance, keep it clean and dry. If you notice any parts getting loose, use the screwdriver to tighten them up. This way, your Micro Gripper Kit A will serve you well for a long time.
