RC Car Control App & Hardware
A comprehensive IoT robotics platform featuring real-time mobile app control over a 4x4 all-terrain vehicle via high-speed WiFi and an ESP32 dual-core controller with live telemetry feedback and custom ARGB lighting.
Hardware Build & Mobile Cockpit
Custom 4x4 RC truck chassis with ESP32-based WiFi real-time control system.
Chassis integration with upgraded steering servo and dedicated DC-DC buck converter.
Top-down hardware view showing motor driver bridge and custom power distribution.
Mobile application touch cockpit with live steering slider and telemetry dashboard.
Addressable RGB LED headlights & underglow customization panel.
Key Features
Real-Time Low-Latency WiFi Control
Direct UDP / WebSocket packet transmission ensuring sub-15ms response between mobile app and rover.
Dual-Core ESP32 Architecture
Core 0 handles wireless network telemetry while Core 1 executes deterministic PWM motor interrupts.
Touch Cockpit HUD Interface
Interactive mobile touch steering slider, throttle acceleration curves, and telemetry gauges.
ARGB LED Lighting Customization
Real-time color picker and lighting patterns for headlights, indicators, and underglow.
Fail-Safe Watchdog Protection
Automatic motor cutoff and emergency braking if wireless connection drops or signals lag.
Dedicated Voltage Regulation
Isolated buck converters prevent electrical noise and brownouts under high-torque motor loads.
