Does this robotic hand kit include the micro:bit mainboard?

No, this kit does not include the micro:bit mainboard. You must purchase a micro:bit V1 or V2 board separately to act as the brain for the expansion board and servos included in this package.

Can I control this robotic hand using my iPhone or iPad?

No, you cannot control this robotic hand using an iOS device. The dedicated Bluetooth control application provided by the manufacturer is currently only compatible with Android smartphones and tablets.

What does the anti-blocking feature on the servos do?

The anti-blocking feature protects the servo motors from burning out. If the robotic finger is blocked by a hard object and cannot complete its programmed movement, the internal algorithm will cut the power to the motor, preventing permanent heat damage.

Do I need to solder any wires to assemble this kit?

No soldering is required to assemble the uHandbit. All electronic components, sensors, and servos connect to the micro:bit expansion board using standard plug-and-play wiring harnesses, making it completely safe for classroom environments.

Can I purchase this STEM kit and the required micro:bit board at your Hong Kong store?

Yes, you can purchase the uHandbit kit and the compatible micro:bit mainboards at Sun Cheong Computer Co. Ltd. (新昌電腦有限公司) in Sham Shui Po. Our technical staff can assist educators and hobbyists in selecting all the necessary components for their robotics projects.

Full Product Description

Interactive STEM Learning with Visual Programming

The uHandbit Robotic Hand Kit transforms abstract coding concepts into tangible mechanical movements for STEM students and hobbyists. By utilizing the Microsoft MakeCode graphical interface or JavaScript, users can easily program complex routines without prior coding experience. This hands-on approach makes learning robotics highly intuitive, allowing beginners to construct a functional bionic hand that reacts to environmental inputs in real-time.

Advanced Anti-Blocking Servos for Durability

This robotic hand is equipped with specialized LFD-01 anti-blocking servos that feature built-in stall protection algorithms. If a mechanical finger encounters an immovable object or gets stuck during operation, the servo automatically cuts power to prevent the internal motor from burning out. This crucial safety feature drastically extends the lifespan of the hardware, making it exceptionally reliable for rigorous classroom experiments and repetitive DIY testing.

Multi-Sensor Integration and Android App Control

The kit includes an ultrasonic sensor for distance measurement and a color sensor for automated sorting tasks. You can program the robotic hand to grab specific objects based on their color or react to approaching obstacles autonomously. Additionally, the system supports Bluetooth connectivity, allowing you to control the hand's individual joint movements directly using the dedicated Android smartphone application (please note that iOS is not supported).

Pro Tip from Our Technicians

Our Sham Shui Po technical team reminds you that this kit requires a separate micro:bit mainboard (V1 or V2) to function, which must be purchased separately. When assembling the acrylic base, ensure the 1501 digital servo is perfectly centered before attaching the hand to guarantee a full 180-degree horizontal rotation. Always use the included 6V 5A power adapter during heavy programming sessions to prevent the 18650 lithium battery from draining prematurely.
