Kit containing everything needed to create an aluminum alloy robotic arm with 4 degrees of freedom and gripper to grip objects, all managed via the micro:bit board (not included)

Kit containing everything needed to create an aluminum alloy robotic arm with 4 degrees of freedom and gripper for grasping objects, all managed via the micro:bit board (not included). The robotic arm, once the micro:bit board has been programmed, can also be controlled via Bluetooth connection via a simple smartphone App.

The electronic board has a connector for inserting micro:bits, a driver based on the PCA9685 chip which allows you to simultaneously manage up to 16 RC servos or LEDs, an I²C interface, a 5 volt voltage regulator capable of delivering a 3 A. The 16 output ports have a resolution of 12 bits, each with 3 pins: V+, GND and PWM output. Each PWM works completely independently, but they all must have the same PWM frequency.

The package includes: 1 analog RC servo (MG996R) with 13 kg•cm metal gears and accessories, 3 analog mini RC servos (MG90S) with 2.5 kg•cm metal gears and accessories, 1 electronic board, 1 mains power supply with micro USB output (5 volts 3A), 1 extension for RC servo (150 mm), 2 screwdrivers, aluminum alloy parts for the robotic arm and all the mechanical small parts necessary for assembly.

Programming environments

  • MICROSOFT PXT (BETA) is a programming environment created by Microsoft (still in beta version) that supports both a Scratch-style block graphical environment and the Javascript language.
  • PYTHON was and still is in development to allow programming of microcontrollers in a Python-compatible language. The opportunity to use the Python language allows for continuity, in a hypothetical educational path, towards the use of more complex systems such as microcomputers capable of hosting GNU/Linux, such as the Raspberry Pi series.
  • MICROSOFT BLOCK EDITOR is a visual editor very similar to Scratch and represents the starting point for those who want to start programming. Like Scratch it is very simple to use but it is not a toy. It allows you to
    deepen structured programming and event management. The method of composing a program consists of choosing the blocks that represent the instructions, dragging them into the editor panel, configuring them in the customizable parts and "fitting" them correctly.
  • MICROSOFT TOUCH DEVELOP was developed to create programs for the micro:bit using tablets or other devices equipped with a touch screen. Obviously it can also be used by normal PCs using a keyboard and mouse.
  • JAVASCRIPT is a development environment that allows those who have made progress in programming to develop programs using the textual syntax of Javascript, with a guided editor that supports the "click and drag" method for composing lines and blocks of code .
Technical characteristics of micro:bit
  • 25 red LEDs that can be lit with different intensities to create drawings, animations and games.
  • Two buttons that can be managed via program to customize its behavior.
  • A reset and restart button.
  • An accelerometer capable of detecting and recognizing different types of movement such as shaking, rotations and free fall. Useful for making a motion sensor or animated games.
  • An electronic compass capable of detecting orientation and rotation in degrees with respect to North. A further use could be as a (magnetic) metal detector.
  • A USB connector to connect the micro:bit to your PC to load software programs.
  • A connector for external power.
  • A Bluetooth Smart Technology module that allows you to connect the micro:bit with other devices equipped with the same technology such as other micro:bits, PCs, smartphones, Bluetooth kits, tablets and cameras.
  • A temperature sensor capable of detecting ambient temperature.
  • A connector with 24 pins, five of which have pads suitable for connection with crocodile clips. Analog and digital I/O, communication bus and other functions described in more detail below are available on the connector.
