DIYables 2WD Smart Robot Car Chassis Kit Pre-Assembled Presoldered, DC Motor Encoder
Click to zoom
Quick Overview
This DIYables 2WD smart robot car chassis kit arrives fully pre-assembled with a durable acrylic frame, dual DC gear motors, and a battery holder, ready to use right out of the box. There's no assembly step, no missing parts to track down, and no soldering required, so you can start wiring and programming your robot car right away with Arduino, ESP32, ESP8266, or Raspberry Pi.
This version improves on the standard kit by having the lead wires soldered directly onto the motor terminals. On kits where wires are only pushed onto the motor tabs, those joints are the first thing to fail — a wire works loose under vibration, or a tab snaps off during handling, and the robot stops mid-run for a reason that is hard to spot. Soldered joints remove that failure point entirely, which matters most in classrooms and workshops where the same chassis is handled repeatedly by different people.
Both DC motors include built-in speed encoders that provide real-time feedback for precise motion control, making the chassis suitable for line-following, autonomous driving, and RC robot applications. All acrylic parts are pre-drilled with standard mounting holes, so you can mount a motor driver, microcontroller, and sensors directly onto the chassis.
Perfect for STEM education, robotics learning, and Arduino or ESP32 programming projects. Step-by-step tutorials are available online, making it easy for beginners and students to go from chassis to a working RC robot car quickly.
Key Features
- Wires Soldered to the Motors — Lead wires are soldered directly onto the motor terminals, so they cannot work loose under vibration or pull off during handling
- Pre-Assembled Chassis — Fully built 2WD chassis with dual DC motors, ready to use out of the box
- Motors with Speed Encoders — Built-in encoders on both motors for real-time speed feedback and precise motion control
- No Soldering Required — All motor and encoder connections are made at the factory, so no soldering iron is needed to get started
- Built for Repeated Handling — Soldered joints suit classroom and workshop use where the same chassis is assembled and rewired many times
- Pre-Drilled Acrylic Frame — Standard mounting holes for motor drivers, microcontrollers, and sensors
- Complete Out of the Box — Includes battery holder, power switch, wheels, and caster wheel, avoiding missing components
- Wide Voltage Compatibility — Works with 3.3V and 5V microcontroller boards
- Wide Compatibility — Works with Arduino, ESP32, ESP8266, Raspberry Pi, and other microcontrollers
- Tutorial Support — Step-by-step tutorials available for Arduino, ESP32, ESP8266, and Raspberry Pi
- Versatile Applications — Ideal for line-following robots, autonomous driving, and RC robot projects
- STEM Ready — Great for robotics learning, coding practice, and classroom projects
