Humanoid Robotic Hand Using Arduino
Humanoid robotic hand is the artificially created mechanical hand visually similar to human hand, it can moves like human hand with the help of motors and motors are controlled by advanced microcontroller with programming. The simulation of humanoid robotic hand with proteus vsm software as shown in video .
Here i used 21 servo motos with 21 corresponding potentiometer.
The proteus design and hex files are given below :

THANK YOU FOR DOWNLOADING
Explanations :
1. Robotic arm controller - Arduino Mega 2560
The Arduino Mega 2560 is a microcontroller board based on the ATmega2560 . It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started. The Mega is compatible with most shields designed for the Arduino Duemilanove or Diecimila.
2. Controlling Humanoid robotic hand - Using 21 potentiometers
Using 21 potentiometer we can control all 21 servo motors at the each joints in the robotic hand . Here we know potentiometer produce analog signal ( varying current and voltage) due to variation of motion . The analog signals from controlling hand it send to the microcontroller (here arduino mega 2560) and this analog value convert to digital value at microseconds , The value of the digital signal between 0 - 1024 positions it mapped to 0 - 255 value and send to the servo motors with PULSE WIDTH MODULATION (PWM) signal with duty cycle 0 -255.
