Using the example we discussed in class, go through the design process to engineer a solution to this problem.
Dr. Sama's dog Lucas (aka Houdini) continuously escapes from their backyard. They have a 6 ft tall privacy fence that he can jump without problems. He can also dig under the fence. They also have an invisible fence on top of the physical fence and he knows how to shorten the battery life of the collar and then escape. They don't want to make their yard unsightly or unusable. They don't want to use inhumane methods. What would you do to safely keep Lucas in the backyard?
