smart guide stick 3d model

Design a realistic 3D model of a smart guide stick for visually impaired users. The stick should be ergonomic, sleek, and lightweight, about 1.2 meters long, with the following features clearly visible: Handle: curved black rubber handle with an embedded vibration motor area and a small voice command button on top. Shaft: silver or white metallic shaft that houses ultrasonic and LiDAR sensors near the upper-middle section. Haptic feedback section: small vibration motor housing along the middle of the stick. Base: rotating electromagnetic wheel at the bottom, slightly larger in diameter than the stick, designed to follow an electromagnetic trail on the ground. Connectivity: small Bluetooth indicator light near the handle. Make the design minimal, modern, and functional, suitable for real-world product prototyping. Use realistic textures (matte metal, soft rubber) and display the stick in a neutral environment or on a simple floor path to show its navigation concept.
