Hi I'm new to this and have built a Arduino obstacle avoidance robot by Lavin with ultrasonic sensor but I'm having difficulties with it not seeing objects on the side and want to add IR sensors to detect side objects and for avoiding steps so it doesn't tumble down our steps to it's death. My thoug…

What have You achieved so far? Please post schematics and code.

[image] stormleopard: very little time to learn this Yes, you do, if you want it to work. [image] stormleopard: my wife How to solve your problem: You sweep and mop until she builds the robot. Here's a time-sharing SR04 simulation that she can incorporate. https://wokwi.com/project…

I’m unsure what it is you want from the forum ? Can you be more specific

What the robot is assembled and working with ultrasonic sensor that includes the coding for it to work minus the IR coding. IR will be connected to which pins I'll read from the code. So either total recode or paste in code .

If I get time I'll check it out

[image] stormleopard: total recode total recode of what? [image] stormleopard: a robot that can vacuum or mop via a hooked trailer that is already made and works So there's a trailer that already sweeps and mops and just needs an autonomous tractor to pull it?

The Lavin Arduino robot pulls the trailer but the ultrasound sensors fail to see walls especially when it nearly runs parallel to the wall which it then rubs against and sometimes it fails to get it away from the wall thus I need IR sensors that can detect this which I have but I need code to integr…

Also the house have some steps that it must see so it won't tumble to it's death.

[image] stormleopard: fail to see walls That is your code not working, the robot only does what it is told. [image] stormleopard: steps that it must see These sensors are not omnidirectional. For every direction you want to sense, you need another sensor.

Yes, you do, if you want it to work.

It looks like you have D3, D8 and D11 free to use for your added SR04.
