Learning Robotics Step By Step

What are the basic components of Robots? Movement. Movement around different axils. So once has to understand the design of movement. And Movements come from motors. There are several type of them, Geared Motors, Servo Motors, Stepper Motors.( No AC Motor in our discussion). So first think of what you are expecting out of the movement.
1) If it needs to carry some wight than servo motor for sure. But servo motor alone can not be controlled for precise movement. So what is the solution? Gears dear friends. Havn't you studied machine design? Just need to design a gear assembly that reduces the rotation par minute of the motor. Have you seen old Cassette players? They will give you the Idea.
2) So as a primary task take a gear assembly, attach it with a servo motor. connect it with 9 volt transformer with a push switch. if you can control the rotation to 10-20rpm, you have it in you to become a robotic and automation engineer. else you are reading a wrong post.

even i tried my hand at robot making just this may! 😀
we did a wired manually operated robot which has to move around the arena and collect the objects of various shapes and sizes using it's claw mechanism. 😀

can you post the gear photo or atleast a project photo?

Cooltwins had shared it here: #-Link-Snipped-#

CP had shared a video. @CP: Please post the video here.

the thread #-Link-Snipped-# shows the basic one we did to learn the basic.
i'll post the pics of the gear mechanism of the arm and pic of my final bot soon 😀

robotics always starts with a mechanical design. what do you want to make is the question.
1. one big misconception students as well teachers have today is a wired bot being called a robot. it is not. a robot should have some kind of intelligence else it is only a machine controlled by wire.
2. also robots aren't just 4-6 wheeled cars. robots can be automated or 'intelligently' controlled machines which can range from a simple gripper to a humanoid.
3. for the intelligence part you need to know micro controller programming.
4. read about 8051 controllers to start with.
ending note: just one person can't do everything, get a group of people who are interested, and divide the work.

ANd if you want to see some easy but serious robotic stuff in action, just visit

start with some thing simple like #-Link-Snipped-# and then move into making bots that can follow lights, etc
if you have a good pal or a faculty that KNOW embedded , then ask him for help in uC programming and stuffs. read more about sensors and stuffs.
