Overview
Self-balancing Robot Car Chassis Kit for building and upgrading a two-wheel self-balancing robot car platform. The kit combines a rigid metal chassis with multiple expansion mounting holes, a closed battery protection box, an upper acrylic expansion platform, and 520 encoder reduction motors for robotics education, DIY builds, and smart car competition projects.
Key Features
- 2mm thick metal bottom plate for sturdy support and durability.
- Bottom plate integrated design with motor bracket to simplify installation and adapt to 520 motors.
- Multiple expansion mounting holes to support add-on modules (examples shown: K210 vision module, 4-channel tracking module, PS2 handle receiver, CCD camera module, electromagnetic tracking module, driver board, operational amplifier module, anti-collision copper columns).
- Upper acrylic expansion platform made of 3mm thick acrylic plate, with mounting holes reserved (including lidar mounting holes).
- Closed battery protection box designed to help lower the center of gravity and protect the battery.
- 520 encoder reduction motors with AB phase incremental Hall encoder feedback.
- 65mm wear-resistant rubber tires (anti-skid type indicated).

| Magnetic loop number | 11 |
| Interface type | PH2.0 6Pin |
| Function | Built-in pull-up shaping, the microcontroller can directly read the signal pulse |
Encoder Output (description)
- Phase difference between the two signals: 100°.
- Motor rotation direction can be determined based on the order of the two signals.
- Travel distance can be calculated based on the number of signal pulses per unit time and the tire circumference.
- If only AB phase pulses per unit time are detected, motor speed can also be measured.
- Example (1:30 reduction ratio): motor outputs 11 pulses per single-phase rotation; maximum output per output shaft rotation: (30*11*4)=1320 counts.
