Day 13: Continuing Work on Sonar and a Completed Hand/ Switch

Today was mainly troubleshooting. We're getting close to having the bot track and locate the can, but there's still some issues. The main one is that the bot seems to pick up sonar reflections of objects that aren't there. The 2nd one is that the bot sometimes doesn't sense the can at all. My partner had to leave early, so that gave me time enough to get started on the hand to grab the colored cans with. I added a switch so that the bot would know to close the grabber when the can is in place. I just barely finished by the end of class, and hopefully the switch is sensitive that it won't just push the can along with it.
