Smart Car robot chassis - 2 levels, 2 DC motors, 4 AA battery holder

Product Overview

• Two-wheeled chassis with two DC motors for robotic movement
• Two-level design for integrating additional sensors and controllers
• Motor outputs connected via plug-in contacts, enabling external control
• Rubber-tired wheels and sliding contacts for power supply
• Integrated battery compartment for 4 AA batteries

Product Description

A two-wheeled chassis with two independently controlled DC motors forms the basis for basic autonomous projects. The two-tier design provides space for sensors and controller boards above the drive level without obstructing the motors. The plug-in contacts at the motor outputs allow wiring to an external motor control module, such as an H-bridge driver or a microcontroller with power outputs.

Each motor is mounted on a drive axle with sliding contacts for power supply. The wheels have rubber tires and handle uneven surfaces much better than rigid plastic wheels. The two independent motors allow turning and straight-line travel at different speeds, depending on the control signals. A skid or caster at the rear helps stabilize the direction of travel.

The integrated battery compartment holds four AA batteries and supplies 4.8 to 6 volts, depending on the battery type. This voltage is fed directly to the motor outputs. Typical applications include autonomous obstacle-avoidance vehicles with distance sensors, light-seeking vehicles with LDR sensors, or simple remote control via a control module. The design also allows for line-following experiments, provided suitable sensors are mounted on the upper level.

An external control module is required to operate the motors, such as an H-bridge or a controller with PWM outputs. The maximum battery voltage is approximately 6 volts with four fresh alkaline batteries. Additional components on the upper level should not be too heavy so that the motors retain sufficient traction.

Safety Notice

If there is any uncertainty, work on electrical connections should be carried out by a qualified electrician. The chassis is intended exclusively for prototypes and development projects, not for use in household electrical systems. Observe battery polarity and avoid overloading the motor outputs.
