    How to make your own Animatronics Robot at home

    Published on Jun 2, 2015

    Animatronics refers to the use of robotic devices to emulate a human or an animal, or bring lifelike characteristics. It is widely used in many famous movie like E.T. , Koi Mil gaya ,Terminator. E.T and Jadoo’s head were animatronics robot, (motor and string guided) with a rubber skin. But in the body there was hidden human. We tried to make the robotic part here using two servo motors. The control circuit was based to 555 timer IC to provide pulses to the servo ( 0.5 to 2.5mS pulse, with fixed time period of 21mS). A multi-turn variable resistor/potentiometer were used to vary the pulse width thus the angle of rotation. The difficult part is the aluminum body. Approx dimensions are given for each parts.

    how to make a very simple Infra Red IR proximity sensor for Robots

    Published on Jun 3, 2015

    Here I have shown a very simple IR circuit to make proximity sensor to detect an object. I can be use it robotics. Also you can fit this circuit in a small box with a buzzer and use it as burglar alarm. This circuit will be used in some upcoming robotics projects.

    How to make a simple obstacle detection and an edge robot car

    Published on Jun 19, 2015

    Here is the method of making a very simple obstacle detection robot car. It can be easily converted to a edge detection robot car. So suppose the car is on top of a table. It will never fall from there as it can detect the edge and takes a turn.

    How to make a robot which can follow an object

    Published on Oct 9, 2015

    Here is how you can make a very simple follow me robot. It can sense the presence of object to be followed using Infra-Red ( IR ) sensor. There are one IR Led and two IR photo diode (with back IR Filter) . When the IR gets reflected from a nearby object and reflected back to both the receivers, thus the transistor based switches power ON both the motors and the robot moves forward. If the object moves left or right then any one motor gets switched on and the robo takes turn.
