Introduction: Arduino - Make a Low Cost Robotic Hand With Wireless Controlled (using NRF24L01)

About: Maker 101; Beginner and intermediate level Maker projects! You can find projects such as "How to" and "DIY" on programmable boards such as Arduino, ESP8266, ESP32 and Raspberry Pi on this channel. The projects…

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.

Step 1: Tutorial for Library Installing and Possible Problems

You can watch this tutorial for library installing and possible problems.

In this tutorial we will learn how to use the nRF24L01 Wireless Transceiver Module.
We will control the servo motor with using the potentiometer via nRF24L01 Wireless Transceiver Module.

Step 2: DIY Flex Sensor

Created the flex sensors myself.

In this tutorial, we will learn how to make and use a flex sensor.
We will control servo motor with a flex sensor.

Flex sensors are passive resistive devices that can be used to detect bending or flexing. The flex sensor shown in this tutorial is a flex sensor that decreases its resistance in proportion to the amount it is bent in either direction.You can easily make a sensor wider and longer depending upon your project.
