Puntey Automatic Car

Autonomous obstacle-navigating robotic vehicle platform

Puntey Automatic Car
01 / Overview & Summary

A microcontroller-guided robotic vehicle featuring real-time ultrasonic ranging, adaptive steering algorithms, and onboard battery regulation for autonomous obstacle avoidance.

02 / Technical Architecture & Story

The Puntey Automatic Car is a student-built autonomous robotic rover designed to experiment with real-time obstacle avoidance, sensor fusion, and motor control kinematics.

Constructed on a custom chassis with four-wheel differential drive, the vehicle continuously scans its forward hemisphere using ultrasonic distance sensors. When an obstacle is detected within threshold distances, an onboard navigation routine calculates clearance vectors and commands the motor drivers to pivot and clear a path.

The vehicle incorporates a dedicated power management circuit to isolate motor inductive spikes from delicate microcontroller logic, ensuring smooth autonomous navigation across diverse indoor surfaces.
