## Description

Robotic Arm is the ultimate mobile controller for your ESP32-based robotic arm. Connect via Bluetooth Low Energy (BLE) and take full control of 6 servo joints with real-time precision.<br><br>Whether you&#39;re a student, maker, or robotics enthusiast, this app makes it easy to control, program, and automate your robotic arm right from your phone.<br><br>KEY FEATURES:<br><br>-- 6-Axis Servo Control --<br>Control Base, Shoulder, Elbow, Wrist Pitch, Wrist Roll, and Gripper servos independently. Each servo has a smooth slider (0-180 degrees) with quick-set buttons for common angles.<br><br>-- Program Builder --<br>Record servo positions as steps and build automated sequences. Create multiple programs, name them, and switch between them easily. Perfect for pick-and-place tasks, demonstrations, and learning robotics.<br><br>-- Loop Playback --<br>Run your programs in a continuous loop for repetitive automation tasks. Toggle loop mode on/off with a single tap.<br><br>-- Smooth Motion --<br>Enable smooth interpolated motion between program steps for fluid, natural-looking robotic arm movements.<br><br>-- Bluetooth Low Energy (BLE) --<br>Fast, low-latency wireless connection to your ESP32 robotic arm. Auto-reconnects to your last paired device for seamless use.<br><br>-- Preset System --<br>Save your favorite servo positions as named presets. Load them instantly with smooth transitions - great for frequently used positions.<br><br>-- Multi-Program Support --<br>Create, rename, and manage multiple programs. Each program stores its own sequence of steps independently.<br><br>-- Configurable Step Delay --<br>Fine-tune playback speed with adjustable step delay from 200ms to 5000ms.<br><br>COMPATIBLE HARDWARE:<br>Works with ESP32-based robotic arms running CodeSkool-compatible UART BLE firmware. Uses the same protocol as the CodeSkool Scratch extension for seamless integration with block-based programming.<br><br>PERMISSIONS:<br>- Bluetooth: Required to connect and control your robotic arm via BLE<br>- Internet: Required for user account authentication only<br><br>Built with care for young makers and robotics enthusiasts by CodeSkool.
