I was organizing all of my robot stuff and I found the remains of an old wall follower that I made five years ago. I was thinking that maybe other readers of the forums might also have some wall follower experiences to share so I started this topic…
Anyway, the control software I used was something that Tim Bower came up with. He is an associate professor at Kansas State in the US. He calls it the Virtual Triangle Wall Follower. You can read about his idea here: timbow11.dreamhosters.com/robot_prog/MobileBot/Algorithms/WallFollow.html
The robot I built used a compass and two Sharp IR range finders to implement his algorithm. I calibrated the two sensors to follow the wall at 10 inches and I thought it was interesting what the robot would perceive as 10 inches when the wall surface and lighting changed during its travels. Here’s the video: https://www.youtube.com/@tomrandell683/shorts
It looks like it got stuck on the door mat. 🙁

Real world jobs have meant I have had to pack away the robot projects since the start of the Easter break until I get a break some time in the future.
Last time I thought about "wall following" was using sonar when following this thread.

Although some aspects of robotics is common to all robot projects the few on this forum with an interest in robotics are working on using different types of robot bases and sensor types and ultimate ambitions for an outcome.
