Arduino enthusiasts looking for a project to keep them busy may be interested in this new low-cost robotic hand which is being created using a little Arduino hardware and programming.
The Arduino robotic hand can be controlled wirelessly via a modified glove, together with a number of servos which control each finger and can be seen in the demonstration in the video below.
Components and Assembly
The core components of this project include an Arduino board, five servo motors, and five flex sensors. The flex sensors are attached to a glove, and as you bend your fingers, the sensors detect the movement and send signals to the Arduino. The Arduino then processes these signals and commands the servos to move the corresponding fingers of the robotic hand.
The servos are connected to the fingers of the robotic hand using fishing lines or similar materials, which act as tendons. When the servo motors rotate, they pull on the lines, causing the fingers to bend. This setup mimics the natural movement of a human hand, allowing for precise control and dexterity.
Wireless Control and Programming
One of the standout features of this project is its wireless control capability. The nRF24L01 wireless module is used to transmit data from the glove to the robotic hand. This module is known for its low power consumption and high data rate, making it ideal for real-time control applications.
Programming the Arduino to interpret the flex sensor data and control the servos is a crucial part of the project. The code needs to read the analog values from the flex sensors, map these values to appropriate servo positions, and then send the commands to the servos. This requires a good understanding of both the Arduino programming language and the principles of robotics.
In this tutorial, we will learn how to make a robotic hand. And how to controlled it via wireless. We will control 5 servo motor using with 5 pcs flex sensor. Also we will controlled robotic hand using with nRF24L01. This video shows the low-cost “robotic hand” construction. You can get excellent results with better flex sensors and servo motors.

Applications and Future Enhancements
The potential applications for this Arduino robotic hand are vast. It can be used in educational settings to teach students about robotics and programming. Additionally, it can serve as a prototype for more advanced prosthetic hands, offering a low-cost solution for individuals in need of prosthetic devices.
Future enhancements to this project could include the use of more advanced sensors and actuators to improve the hand’s precision and responsiveness. For example, using high-quality flex sensors and digital servos could result in smoother and more accurate finger movements. Additionally, integrating machine learning algorithms could enable the hand to learn and adapt to different tasks over time.
