I'm trying to build an end of arm tool that will pick up pop cans, water bottles, garbage, etc. I've been searching the web and I got the idea of using vacuum cups. What components would I need to build an end of arm tool with a vacuum cup. I think I need a compressed air source, a vacuum generator and a vacuum cup? I'm looking for a cheap solution so any suggestions are welcome. Non-vacuum cup ideas are also welcome.
Thanks!
