Overview
About Robocraze DIY 4-Wheel Drive Robot Smart Car Chassis Kit with Speed Encoder (Longer Version).
The Robocraze DIY 4-Wheel Drive Robot Smart Car Chassis Kit is a two-layer 4WD platform built around 200 RPM TT gear motors and speed-encoder disks. It is the longer, roomier version of the popular 4WD base and a widely used robot chassis for education and hobby robotics across India.
The upgrade here is the TT (yellow twin-gearbox) motors rated at 200 RPM, which are stronger and more standard than plain BO motors, plus the included encoder disks for closed-loop speed control. The longer double-deck frame gives extra length for mounting a full sensor array, driver board, battery and controller with room to spare.
At around Rs 850, the Robocraze branding means consistent quality and reliable India availability with fast delivery. It is a favourite for line-follower, obstacle-avoidance and PID-based robotics learning projects that need a dependable, well-supported platform.

Buying guide
How to choose.
Choose this Robocraze 4WD kit if you want a dependable, well-stocked platform with real TT motors and encoders rather than a bare-bones generic base. The 200 RPM TT motors give a good balance of speed and torque, and the included encoder disks make it ready for accurate PID speed control right away.
The longer two-layer frame is the reason to pick this over a compact 4WD: it gives you the deck length to mount a 5-channel IR array, an ultrasonic sensor on a servo, a driver, a controller and a battery without cramming. If your build is simple, a shorter/cheaper 4WD may be enough.
Pair it with an L298N motor driver (wire left pair and right pair together), an Arduino UNO or ESP32, IR speed sensors for the encoder disks, and a 7.4V 2S Li-ion pack. Robocraze branding usually means quick India shipping and consistent part quality.
FAQ
Common questions.
What motors does this kit use?
It uses four TT gear motors rated at 200 RPM, the standard yellow twin-gearbox motors, which are stronger and more consistent than plain BO motors.
Does it include speed encoders?
Yes. Speed-encoder disks are included. Mount them on the motor shafts and pair with IR speed-sensor modules to measure RPM, speed and distance for PID control.
How do I wire four motors?
Connect the two left motors together to one L298N channel and the two right motors to the other channel. Each side then drives as a unit for differential/tank steering.
Is it genuinely available in India?
Yes. It is a genuine Robocraze-branded kit that we keep in stock, so availability and delivery across India are reliable.
What else do I need to finish the robot?
You still need a motor driver (L298N), a controller (Arduino UNO or ESP32), a battery pack (7.4V 2S recommended), IR speed sensors for the encoders, and any project sensors like IR line or ultrasonic modules.
