Hi, LMRians. I've been reading up on this Wavefront Algorithm Navigation and I understand bits and pieces of it, but not everything. I'm trying to learn up on it so I can use it in my next robot : Project 4L-FRED (Alfred), a butler robot. The robot is suppose to navigate around the house from the dining area to the living room and serve drinks to guests. The robot will have pre-recorded messages like greetings and stuff like asking what drinks the guest would prefer.
