PRODUCT DESCRIPTION – VERSION 1

(Motor Completely Inside the Chassis)

N20 Line Follower Robot Chassis – Fully Enclosed Motor Design

The N20 Line Follower Chassis – Version 1 is a compact, rigid, and competition-ready robot base designed specifically for high-speed and stable line follower robots. In this version, the N20 motor is completely enclosed inside the chassis, providing superior protection, better balance, and a clean professional look.

Manufactured using high-quality 3D printing material and reinforced with metal fasteners, this chassis ensures durability, precision alignment, and vibration resistance during sharp turns and high-speed runs.

This version is ideal for students, robotics competitions, and research projects where compact width and motor safety are critical.
