Infrared is cheap( $10 -$20) and not very accurate , ultrasonic is expensive( $20+ ) and more accurate.
QuoteInfrared is cheap( $10 -$20) and not very accurate , ultrasonic is expensive( $20+ ) and more accurate. This isn't really true. It greatly depends on how its used, why its used, the environment, etc. Sharp IR has much better pin point accuracy than sonar.You should talk more about the strengths and weaknesses of each sensor, perhaps how the sensors can work together to make up for each others faults.For example, in the land of pillows, sharp IR wins. In the land of bright sunlight, sonar wins.Oh for both of your tutorials ,your commas ,periods , and parentheses are all in odd locations (,you should check on that .)
well , nice tut but ... you kind of trashed the sharp IR next to the sonar, i have a different point of view,,,you have not mentioned that the ultra-sonic has a beam so wide that makes it a stupid sensor in many many bot applications(30 degrees).the only thing sonars are above sharp irs is the long range ..
