Conquer Rough Terrain: 4WD Arduino Robot Kit with Ultrasonic Obstacle Avoidance

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit lets you assemble a four-wheel-drive robot that can traverse gravel, sand, and uneven workshop floors. With two L298N motor drivers and Arduino's PWM, you command each side independently for sharp turns and smooth acceleration. The HC-SR04 ultrasonic sensor gives it autonomous obstacle avoidance, making it a great platform for robotics competitions and college projects.

What You'll Build

You'll build a fully functional 4WD robot chassis powered by rechargeable 18650 cells. It drives forward, backward, and pivots in place, while the front-mounted ultrasonic sensor scans for obstacles and automatically steers clear. Once assembled, you can program it for line-following, remote control, or maze-solving - the chassis is a blank canvas for advanced robotics.

What You'll Learn

• Program Arduino Uno for PWM speed control of TT gear motors
• Wire dual L298N motor drivers to power four motors
• Integrate HC-SR04 ultrasonic sensor for obstacle detection and avoidance
• Debug power distribution with diodes, capacitors, and battery protection

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for CBSE Class 11-12 students building their first differential-drive robot for school exhibitions or ATL Tinkering Lab projects. B.Tech ECE and EEE students can use it as a base platform for Smart India Hackathon challenges involving autonomous navigation. It also fits hobbyists at makerspaces and engineering clubs at NITs or VIT who want a ready-to-code 4WD platform without sourcing parts from multiple vendors.

Built and Backed by Compoden

Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
