uHand UNO

An open-source Arduino robotic hand with knob and app control, and a somatosensory glove in the Advanced Kit.

  • Arduino
  • Suggested for secondary

uHand UNO is an open-source robotic hand for beginners, built on an Arduino UNO with an Atmega328. Six anti-blocking servos move the fingers and the rotating base, and a 6-channel knob board lets learners drive each joint by hand and record motions offline. The hand is programmed in the Arduino IDE with commented open-source code, and can be controlled from an iOS or Android app over Bluetooth. The Standard and Advanced kits add sensors and an ESP32-Cam vision module, and the Advanced Kit adds Hiwonder's somatosensory glove. Every kit comes as a left or a right hand.

What it does

Built for.

  • Arduino compatible

    uHand UNO is fully compatible with Arduino hardware interfaces and the Arduino IDE. Hiwonder provides commented open-source code, schematics, video guides and project tutorials.

  • Knob control and offline editing

    Six knobs move the joints directly, and motions can be recorded with the knobs and buttons and played back without a computer.

  • Sensors (Standard and Advanced Kit)

    A glowing ultrasonic module measures distance and starts ball grabbing, an acceleration sensor controls the grip by pose, and a touch sensor runs finger counting.

  • AI vision (Standard and Advanced Kit)

    An ESP32-Cam module adds colour and face recognition, and the app can show the camera's image.

  • Somatosensory glove (Advanced Kit)

    The Advanced Kit includes Hiwonder's wireless glove for somatosensory control of the hand.

  • Anti-blocking servos

    A built-in stall protection algorithm keeps the servos from burning out if a finger is blocked or hits something.

Where it is used

Applications.

  • Introductory Arduino programming with a physical robot
  • Teaching servo control and the mechanics of a hand
  • Sensor projects with distance, pose and touch (Standard and Advanced Kit)
