A cloud-connected autonomous robot with PS5 controller support, robotic arms, and real-time Firebase integration.
Six core systems working together for a seamless robotic experience.
Four-wheel drive with dual DC motors providing robust maneuverability on any terrain. Precise directional control with analog input.
Dual servo-driven arms with 180° range and 13° precision increments. Six preset positions plus full manual control for gripping tasks.
HC-SR04 ultrasonic sensor with real-time distance measurement every 50ms. Automatic obstacle detection triggers at 20cm threshold.
Firebase Realtime Database integration for remote messaging, call notifications, and AI commands. Updates every 4 seconds with thread-safe access.
Full Bluetooth LE integration with DualSense controller. Analog stick driving, button-mapped arm control, and mode switching via D-pad.
Five-state obstacle avoidance: drive, stop, reverse, pause, turn. Fully autonomous navigation with intelligent path correction.
Three simple steps to interact with El3tra.
El3tra auto-connects to WiFi via WiFiManager. If no network is saved, it creates its own hotspot "El3tra" for easy configuration.
Use the PS5 controller for real-time manual control, or switch to autonomous mode. The web control panel lets you send messages, calls, and AI commands remotely.
El3tra responds with LCD messages, audio notifications, and intelligent movement. Real-time feedback through its display and sound system.
