IR vs Ultrasonic Sensor

I have used ultrasonic sensors in the past. However, i have noticed they have a wide arc of vision. I want very precise sensor readings for my new project, and I was curious as to the pros and cons for either sensor option, or something else. I am mainly looking for affordablilty and precision.

Object avoidance with the Ultrasonic sensor

I am making a robot using arduino and i need an easy object avoidance code

Here is what i found:

 

 

#include "URMSerial.h"

 

#include <Servo.h>

Servo lservo;

Servo rservo;

// The measurement we're taking

#define DISTANCE 1

#define TEMPERATURE 2

#define ERROR 3

#define NOTREADY 4

 

int ledPin = 13; 

URMSerial urm;

 

void setup() {

  Serial.begin(9600); // Sets the baud rate to 9600

Ultrasonic Transducer Transmitter\Reciever

HI,

 

I am trying to make an ultransonic obstacle sensor, I just need to know if the Transmitter and reciever have polarity? And if so how do I tell which is the Cathode and which is the anode?

The transmitter and reciever I have are the following.

My Hexapod with Ultrasonic Sensor

Hallo!

I want to show you my newest Video.

It´s my completely self built Hexapod !

Programmed with Bascom AVR. I am working on it since 2009. Last Winter I gave it a Ultrasonic Sensor.

Sorry for my bad English but thats not my daily Work.

More Informations about the Bot are in the Youtube Discribtion.

I hope you like it.

Waterproof ultrasonic sensor?

Can I unsolder the transducers from the Parallax PING sensor and replace them by these ones: http://www.parallax.com/Store/Sensors/ObjectDetection/tabid/176/ProductID/755/List/0/Default.aspx?SortField=ProductName,ProductName? They operate at the same frequency. Also, why does the PING sensor have two transducers? I guess one is a transducer and the other is a receiver, but is it the same part?

Area mapping

I have (that is relative because I have not yet ordered my first parts from Robotshop) a PING ultrasonic sensor. I'll be having an arduino mini - though I'll no doubt buy something bigger after - and I wonder if I can efficiently make my upcoming rover (differentially driven, nothing special really) map it's surrounding area using a grid. Is it possible or will I run short on memory with the arduino mini? And more importantly, I need help with the code (I have 0 experience with code, though I have enough theory I guess...). Any suggestions are appreciated.

Ultrasonic sensor

Hi,

I have this ultrasonic sensor, it's from a part of a Cybot. I was wondering if anyone's used one of these on a Picaxe and if so, did it work?

It's a 9v part, so I'm unsure if it will work on Pcaxe.

ultrasonic sensors from Cybot

I'm trying to understand this sonar-board from my old cybot robot, but I think I will need a little help :

http://www.lpilsley.co.uk/cybot/sonario.htm

- If I'm correct I should put a voltage on the transmitter sensors for a short period of time (100 ms?), then read in the value of pin 2 and 3, right?

- What voltage should the transmitters get? 5V?

LV-MaxSonar Sensor Questions

Hello,

This is my first post here at LMR. I decided to write out a question in the format of a blog. Since I've had some trouble getting my head around this issue and I found limited resources regarding this special device on the Internet. Creating a blog post might help other people with similar questions as me. 

Dagu's Ultrasonic Sensor testing

I've made some testing with the ultrasonic sensor from Dagu. Tests were made on the platform the sensor is build for, the Asuro. The sensor works pretty well, most of the the time. The range of obstacle detection is from 0..25cm. Sometimes the sensor dismiss an obstacle, when the objects is not directly in front of the robot.

 The video gives some impressions, how this sensor works.
