The prompt
Create a simple but realistic 3D CAD model of an inclusive assistive reaching device called “IncluStick”. The product is a lightweight motorized grabber designed for people with reduced grip strength, arthritis, or limited mobility. Design requirements: * Long cylindrical hollow shaft, approximately 600 mm long and 25 mm diameter. * Ergonomic handle at the bottom, approximately 120 mm long and 35 mm wide. * Large soft-touch push button on the handle. * Small Arduino Nano compartment inside or attached to the handle. * Small battery compartment beside the Arduino. * Thin wires running from the handle through the shaft to the motor. * Small servo motor near the top of the shaft. * Two mechanical gripping jaws at the front, approximately 80 mm long. * Jaws should open and close using the servo motor. * Add textured rubber/non-slip pads to the inside of the jaws. * Add a small camera module next to the jaws, facing forward, to provide a view of the object being picked up. * Make the camera small and lightweight so it does not interfere with the jaws. * Include a simple rotating joint between the shaft and gripping head. * Keep the overall design compact, lightweight, ergonomic and realistic enough to manufacture as a school prototype. * Use simple shapes and components so the model remains easy to edit in Tinkercad. * Clearly separate the main components and make them visible. * Add dimensions or dimension labels for the overall length, shaft diameter, handle size, jaw length and camera position. * The final model should look like a functional inclusive assistive product, not a complicated robot. * Use a clean, modern appearance with black/dark main body and yellow accents around the button and functional areas. * The model should be suitable for presenting as a detailed B4 planning/CAD model for an MYP Design project.
