1. Prdouct Description

miniArm is an open-source robotic arm tailored for beginners. Built upon Atmega328 and compatible with Arduino, it boasts a 6-channel knob controller, Bluetooth module, high-precision digital servos, and other high-performance hardware.Additionally, it offers several interfaces reserved for sensor expansions,enhancing user flexibility for secondary development.

1) Arduino Compatibility:

Fully compatible with Arduino hardware interfaces and software compatible with Arduino Interfaces are fully compatible with Arduino,and software is compatible with the Arduino IDE. Open-source code with detailed comments are provided for your development.

2) Dynamic Control with Knob:

Control robotic arm joint movements quickly through the knob potentiometer, immersing yourself in the seamless operation of the robotic arm.

3) APP Control:

Take command of miniArm effortlessly through app, allowing you to execute desired actions with the tap of a button or the swipe of a slider.

4) Offline Motion Editing:

Record robotic arm motions swiftly using the knob potentiometer and buttons. This feature allows offline motion editing and operation.

2. Hardware Introduction

1) Anti-blocking Servo:

Equipped with built-in stall protection algorithm, ensuring the servo won't burn out due to blockage or collision,significantly extending its lifespan.

2) Support AI Vision Module:

The miniArm can be expanded with ESP32Cam module to unlock a wider range of creative vision applications.

3) Built-in Bluetooth Module:

The miniArm expansion board loads a Bluetooth interface for integration with Bluetooth module. This feature will be helpful for your project development.

4) Boundless Creativity:

Expand the capabilities of miniArm with avariety of sensors and unlock endless possibilities for your project.

3. Support Sensor Expansion

Equipped with a sensor expansion pack including Esp32-Cam vision module, glowy ultrasonic sensor, touch module, acceleration sensor and more. You can program to unleash capabilities such as visual tracking, color sorting and distance measurement

1) Sonic Ranging:

Users can position obstacles in front of the glowing ultrasonic module of miniArm and then move the obstacle toward miniArm. The robot will respond differently, and its RGB light will change based on the distance from the obstacle.

2) Pose Control

Utilize an acceleration sensor to detect the pose, which in turn regulates the gripping and placing actions of the robotic arm.

3) Sonic Ball Grabbing

When the glowing ultrasonic module of miniArm detects an object, the buzzer on the expansion board will emit a sound, and the RGB light will turn green. At this point, the user can place a ball in the center of the robotic arm, prompting the robot to grasp the ball and initiate rotation to the left side to release it.

4) Touch Grabbing

Users can activate the miniArm, turn it on and start controlling it by touching the touch sensor's metal plate. Touch the robotic arm to pick up the block, then touch the robotic arm to place the block. At the same time, you can also control the color change of the RGB light.

4. Equipped with Al Vision Module

miniArm can be equipped with an ESP32-Cam module, which can realize creative functions such as color recognition and sorting, color tracking, face recognition and vision image return.
