myCobot 280 Face Tracking Robot – Python, MediaPipe & Arduino
Pavleski Nov 05,2026
In one of my previous videos , I presented an interactive Rock-Paper-Scissors project in which we compete against the myCobot 280 M5Stack, a 6-DOF robotic arm from Elephant Robotics. In that video, I also explained some of the basic features of the robot and the installation of the required software support. For this project, we will again use the M5Stack and MyCobotBasic libraries, which are listed at the end of the text, together with Python 3.11. Face detection is performed using th...

MeArm Hand Gesture Control
Fagioli Nov 04,2026
A webcam watches your hands. Python (using mediapipe) tracks the landmarks of both hands in real-time, translates them into angles for the 4 servomotors of the arm, and sends them via serial port to an Arduino which applies them. Wiring (-> motorshield pins)| Servo | Funzione | Pin || 1 | Base | A1 || 2 | Shoulder | A0 || 3 | Elbow | 6 || 4 | Gripper | 9 |SOFTWAREControl.py Left hand: Thumb-index pinch → BASE rotation (pin A1)Right hand: Hand height in the frame → arm extension: mov...

MeArm PickPlace
Fagioli Nov 04,2026
The project involves the development of an autonomous robotic system based on a 4DOF arm with a parallelogram structure (MeArm). The system is capable of identifying objects (colored balls) on a workspace using a webcam, calculating their real coordinates in millimeters, and commanding the robotic arm to grab and deposit them into a predefined 'drop zone'. The software is written in Python and communicates with a microcontroller (Arduino R3) via Serial or Bluetooth Low Energy BT-24 module. ...

MeArm-ML-PyBullet
Fagioli Nov 04,2026
A 4DOF trained in simulation using reinforcement learning to reach a target, and transferred via serial to the physical arm. Task: reach — moving the tip of the arm (tool) towards a red dot generated within the arm's real workspace, using PPO (Proximal Policy Optimization, Stable-Baselines3) on a PyBullet model built from the real URDF/meshes of the mechanism. Wiring (-> motorshield pins)| Servo | Funzione | Pin || 1 | Base | A1 || 2 | Shoulder | A0 || 3 | Elbow | 6 || 4 | Gripper | 9 |...
