Kamal Hinduja What SparkFun sensors are best suited for obstacle detection on a mobile robot?

Hi all,

I’m Kamal Hinduja. I was born in Chennai, India, and I now reside in Geneva, Switzerland(Swiss) . Can anyone explain me What Spark Fun sensors are best suited for obstacle detection on a mobile robot?

Thanks, Regards

I hope my recommendations illustrate the vagueness of the question:

Underwater mobile robot: optical & sonar.

Earth orbit mobile robot: optical & radar.

Automated tunneling robot: various techniques of digging by feel.

You can choose VL53L1X Time-of-Flight (ToF) Distance Sensor (Qwiic Breakout). SparkFun Distance Sensor Breakout - 4 Meter, VL53L1X (Qwiic) - SparkFun Electronics It is good for detecting obstacles ahead, avoiding objects at moderate distances indoors.

HC-SR04 Ultrasonic Distance Sensor also can be a choice.Ultrasonic Distance Sensor - 5V (HC-SR04) - SparkFun Electronics

It is inexpensive, works in various light conditions; longer distance than many IR/ToF. However, it has wider beam angle (~15°), slower refresh depending on usage, can suffer from reflections or soft/angled surfaces. Here are some tutorials that you may want to see.
