The biggest differences between Fluke & Craftsman are accuracy and durability. The Fluke is meant as a measuring instrument, used hundreds of times a day every day - someone's salary depends on it working. The Craftsman is meant for the more casual user, a few times a month.

Buy the Craftsman for robotics usage.

(I am a huge fan of Fluke products, but for what you're going to be doing with it, the money's not worth it).
