Kids OK with adult2× ESP32Level 3/3
Gesture-Controlled Robot Arm
Wear a glove with a tilt sensor. The arm copies your hand, with no wires and no app.
Kids OK, with an adult
DIY project. Children must build this only with an adult (16+ years) beside them at all times. Not suitable for children under 8 years.
In the glove code use Wire.begin(25, 26) for the I2C pins.
Strictly follow the description given with this video.

The video link will be added here soon.
How it works
- The MPU6050 on the glove measures how your hand tilts and rolls.
- ESP32 #1 sends the angles over ESP-NOW, a direct radio link with no router.
- ESP32 #2 on the arm turns the angles into servo positions.
- The finger button closes and opens the gripper.
