uHandbit robotic hand in black acrylic and metal, with an ultrasonic sensor on the front of its base

Robotic hands

uHandbit

A micro:bit robotic hand with ultrasonic and colour sensors, programmed graphically or driven from an app.

  • micro:bit
  • Suggested for primary
  • Suggested for secondary

uHandbit is a programmable robotic hand powered by a micro:bit and a micro:bit expansion board. It can be controlled from a PC, from the micro:bit itself or from a mobile app, and supports graphical programming. With its ultrasonic and colour sensors it measures distance, recognises colours and counts on its fingers. Anti-blocking servos with built-in stall protection move the fingers. It is sold with or without a micro:bit V2.0.

What it does

Built for.

  • micro:bit control

    The micro:bit and its expansion board form the control system, and the hand supports graphical programming in the browser.

  • Sensors

    An ultrasonic sensor and a colour sensor are supplied for distance measurement and colour recognition, and the hand can count on its fingers.

  • Anti-blocking servos

    LFD-01 anti-blocking servos move the fingers, with a built-in algorithm that protects them when they are blocked. A digital servo in the base turns the hand 180 degrees horizontally.

  • Three ways to control it

    Drive it from the mobile app, from the micro:bit or from a PC.

Where it is used

Applications.

  • micro:bit programming with a robotic hand
  • Sensor projects with distance and colour
  • Teaching how servos move fingers
  • Introductory robotics for primary and secondary learners
