The Hiwonder Armpi Pro Raspberry Pi ROS Robotic Arm Developer Kit w/ 4WD Mecanum Wheel Chassis Open Source Robot Caris developed upon the Armpi FPV Vision Robotic Arm, adding an omni directional mecanum wheel car which can realize moving, picking, target tracking, and intelligent transporting. The removable mecanum wheel car makes it flexible to switch between two models: desktop robotic arm and mobile robotic arm. With ample tutorials and open source Python codes, the Armpi Pro is the perfect platform to learn ROS, robot technology and robot vision, reducing the project development period and allowing for a full experience of AI.
1. Omni Directional Movement and First Person View
1) 360 Degrees Omni Directional Movement
The Armpi Pro is equipped with four high performance encoder geared motors and four omni directional mecanum wheels, enabling 360 degree movement. The various movement modes (forward, horizontal, diagonal, and rotational) and excellent performance make it suitable for challenging complex routes.
2) Object Transport and First Person View
The Armpi Pro is loaded with an Armpi FPV Vision Robotic Arm, allowing for easy picking and transporting of the target. When combined with the HD camera ending in the robot arm, it can provide a first person view.
2. AI Vision Recognition and Target Tracking
The Armpi Pro uses OpenCV as its image processing library and utilizes the FPV camera to recognize and locate the target block, enabling color sorting, target tracking, line following, and other AI games.
1) Color Tracking
Through vision positioning of the target object and inverse kinematics algorithm of the robotic arm, the target object can be accurately targeted and tracked.
2) Color Sorting
With abundant tutorials and open source Python codes, the robotic arm can carry out color recognition, picking, and sorting.
3) Line Following
Line following is implemented by ROI area extracting with OpenCV, noise elimination, image binarization, and direction calibration with PID algorithm.
3. APP Control and FPV Transmitted Image
Android and iOS apps are available for robot remote control. Through the app, you can control the robot in real time and switch between various AI games with just one tap.
1) First Person View and HD Transmitted Image
The Armpi Pro supports WLAN and WIFI direct connection modes. After WiFi connection, the first person view will be transmitted to the app interface, providing an exciting and realistic robot control experience.
2) Real Time Remote Control and Picking and Transporting
Use the app to control the Armpi Pro to move, pick, and transport with ease.
3) Quickly Experience AI Games
Switch game modes easily and quickly to experience various AI games.
4. Hardware Features
1) Hard Aluminium Alloy
The hard aluminium alloy protects the core control board from shattering and shock, and can bear heavier loads.
2) Encoder Motor and Encoder Motor Driver
The encoder motor with a large reduction rate can offer accurate calculation of wheel speed and travel distance. The four channel encoder motor driver contributes to easier motor control.
3) HD 120 Degrees Wide Angle Camera
The Armpi Pro is loaded with a 120 degree wide angle camera, allowing it to look around 180 degrees and up and down 180 degrees. Combined with the mecanum chassis car, its visual range is up to 360 degrees.
4) High Performance Serial Bus Servo
It can provide voltage and position feedback, and stronger force. Its built in anti blocking algorithm results in a longer service life.
5) 12000mAh Large Capacity Lipo Battery
The built in 12000mAh large capacity Lipo battery greatly invigorates the robot and prolongs its working life.
