Hey guys I'm new to the site, it looks very interesting and I know I will learn a great amount of information from you all. Anyway i'm a Senior in Electrical Engineering at University of Louisiana and I need some input on a couple of design ideas.
I'm working on a senior design robot project, and it involves determining the weight of 3 cans. The competition requires us to determine the weight of 3 cans, and then orgranize them on a competiton board based on 3 distinct weights: 63g, 128g, and 198g. We want to be able to determine the approximate weight of the can by only using a sonar type or some other system.
The main idea is to determine the weight of the can without having to drive up to the can and pick it up; ie save critical time in the competition. Do you think that a sonar type system can actually determine the difference in density level between the 3 cans? I don't know much about sonar, it was just an idea.
what do you guys/gals think? thank you in advance!!
