robotic arm 3d model

A detailed 3D render of a desktop robotic arm kit designed for student engineering projects. The arm mechanism is constructed from neatly cut blue acrylic pieces, connected by three small blue SG90 servo motors at the joints, ending in a functional mechanical gripper claw. A single USB data cable runs from the arm to a sleek laptop visible in the background showing hand-tracking skeletal lines on the screen. Industrial design style, bright studio lighting, soft shadows, dark minimalist background
