The project was supposed to be a pneumatic robotic arm, but has been modified into a hydraulic arm, using a water pump instead of an air compressor and air tank! This doesn't change much in terms of design, because like air, water remains a fluid. this note is to avoid any confusion when reading the first project logs

The aim of our project is to make an pneumatic robotic arm controlled by an IOT interface; 
Knowing very little about pneumatic system and linear motion, it's an ambitious project for us. 

We started making research on the major component that we'll need in order to make a pneumatic system :

• Pneumatic actuator
• Control Valve
• Air compressor
• Air Tank

Taking inspiration from other this is what we are aiming for (but using pneumatic instead) : 

Since we want to control the pneumatic arm by an IOT interface, the control valve making the the actuator extend or retract will ne to be electrically controlled by a microcontroller, we settled on the use of an ESP32 with a webserver
