Basic parts of an humanoid robot.

Animatronics.

 Robots are intelligent machines,they don't have to look like human,robots was coined from a chzeck language "robota" meaning to enslave,robots have types and classifications but they all perform a specific function autonomously.we we will learn about basic parts of  robot all enthusiastics, hobbyist and roboticist should know about.

A robot should contain all this parts listed below:

The manipulator:we humans have arms right,but what do robots have?you say arm? Yes you are right! but we call it manipulator in robotics, robots arms are called manipulator because they are are used to manipulate things.A human arm has 3 joints so your robot can have same to depending on your taste,human arms also has 6 degree of movement meaning that human hand rotates or twist in only 6 directions.

End effector:they are the robot hand or you can call it finger if it is for humaniods,they are used for gripping,holding and it can do all what man can do.bots can have their end effector as soldering iron,drills vacuum sucker for gripping objects, thermometers etc.

Controllers:this are circuits,socket boards or panel that contains chips that are reprogrammable and use for controlling robots motor,sensors,servos,rob-ot joints etc.An example of robot controller is an Arduino.

Power Supply: these are power sources for your bot,bots can be powered with batteries,main socket that is for those used in automobile industry,organic materials, solar cells etc.

Sensors: these are used by bots for connecting to the real world,they are used for sensing the environment, avoiding obstacles,ballancing on rough terrians, sensing images and a millions application for your bot.

Actuators:these are components that converts signals from sensors into movements,they can be motors for driving the joints of a bot.

How to program an arduino with a smartphone.

H ow to program an arduino with a smartphone Before, we can only program an arduino with a laptop or desktop computer ,but most hobbyist doesn't can't afford to buy one but thanks to the new era of Technology we can now program our board with our smart phone any where we like and at any time.To program an arduino you need to download Arduino droid or arduino commander from the Google play store, I prefer arduino droid to Arduino commander because of it flexibility and ability to understand.To start coding with your phone you need a knowledge of c++ language,the Arduinodroid is both a compiler and an editor that is you can compile your skecth right after writing it. How to program with your smartphone . You will need an OTG cord to connect your Arduino to your phone for skecth uploading since the arduino cord can't directly connect to it.you can only use an android phone with version 2.0 or higher. When trying to upload your sketch the board will feed current from your phon...

How to make a powerbank with 9v battery.

Home made 9v power bank. U  In this article we will learn how to make a power bank for our phones in case of emergency,smartphone has became a very unique device in the life of men but the only problem is the power source to keep it running on.we have many diy power banks we can make like rechargeables,4000mah power bank,non rechargeables,hand driven charger etc.So let's cut our story shot and go straight to the point. Materials. 1.ic7805cv that is for regulating 9v_5v 2.old USB. 3.wires for connection 4.LED,.1k resistor,if you wish to add an indicator bulb. 5.9v battery. Circuit diagram below. good luck!!!!

Beginner guide to electrical components and description.

Electrical components are commonly found on circuit boards and their presence is ubiquitous in mordern engineering here are some lists of materials you need to be familiar at: 1.Capacitor Symbol of capacitors. It consists of two metals separated by a dielectric material,it is use for storing charges.types: Ceramic, electrolytic,film and vairable capacitors.electrolytic is grouped into aluminum and tantalumcapacitor.Applications range from storing electric charge, stabilizing current, reducing riples in voltage and use in radio for tuning. 2.Diode Diode symbol. It is use for rectifying DC from ac since it only allows current in one direction,the part with white strip is the negative pole known as the cathode while the other black area is the positive side called anode.types of diodes:Zener,LED known as light emmiting diode, photodiodes,avalanche diode. 3.Transistors Transistors. it is basically used for amplification,switching, regulating and control it is made of semiconductors and has...
