The Simplest Line Follower – Upgraded! [Updated]

Hello everybody!

Apologies for not writing for so long! Work has kept me really busy so I wasn’t able to do much till now.

Last week I finally got time to do a bit of work. I made my own PCB :). I wish I had learned this back in college. It have would saved me so much time.  What PCBs did I make? The line follower circuit (Click me to open tutorial) I explained before. That design had two very irritating problems. Firstly the wires would keep breaking off and I would have to re-solder many times. Secondly, the cardboard mounts would keep bending.

The new robot uses very little wiring. None of the wires have been soldered. I have also replaced the mounts for the sensors. I will describe everything in today’s post. Read more of this post

Bruno The Simplest Line Follower – The Workshops :)

This post comes after I bumped into a video I should have posted along with the tutorial on this robot. As I said in that tutorial, the robot (I named it bruno later) was made for a workshop. This workshop was held two and a half years back and was a huge success considering the last minute planning and the limited help we had. Here is a video of me at the workshop which I happened to find on youtube today. Can’t believe I forgot this one. Here you go…

Cookie the Table Following Robot – Tutorial

I’m back again for another tutorial on robots. This one will be on the table following robot of which a video was posted earlier. For those who haven’t seen it, here is the video again (Wish I had a larger table :( ):

Coming Soon… A Table Following Robot

Introducing Cookie – the table following robot. I will be posting a tutorial on how to build one of these yourself. Keep checking!

Features to be added later:

  • Obstacle detection.
  • Manual Control

My aim is to build a robot that is remote controlled. However, if it encounters an obstacle or the edge of the surface on which it is moving, the robot takes control of itself and moves away from the obstacle or turns to avoid falling from the edge. However I will post on building just the table follower first.

The Simplest Line Follower [Updated]

Alright! First robotics project on the site :-)! This is a robot I made for a workshop, which I conducted under my college’s IEEE chapter. The robot is the simplest line follower you can make and I feel everyone who wants to start with robotics and does not know how to, should begin with this one. It does not need a microcontroller or any complex digital logic circuit. So you don’t have to worry about writing code in C and Assembly. You don’t need to worry too much about the design either. This robot is based on another line follower I had learned at a workshop (conducted at M. S. Ramaiah Institute of Technology, Bangalore). There is a difference of just one IC. The change was due to that fact that my robot uses 12V motors while their’s used 5V motors (with a gear system). Basic idea remains the same.
Note: If you are interested in a microcontroller based line follower I suggest checking this out http://www.kmitl.ac.th/~kswichit/LFrobot/LFrobot.htm
Before we begin. lets see the robot work!
Notice that the track is very simple. Read more of this post
