The primary advantages of thermocouples are their robustness, wide temperature range (-270 degree to 3000 degree), fast response, availability in several package types, and low cost. Looking at their limitations, they suffer from low accuracy and high noise.

The model begins in the upper left with a current source, which is the analog to heat being added to the system. The current flows into both the die’s thermal capacity as well as its thermal resistance. From the die, heat flows into the lead-frame as well as the package potting material. The heat passing into the leadframe flows into the interface between the package and the heatsink. From the heatsink, heat flows into the thermal ambient. The voltages throughout the network represent the temperature rise above ambient.

Everybody needs a body, a skeletal structure upon which to attach all of the other stuff. In a human, this is obviously made of bone. In robots, it's made of just about everything but bone. Robot builders are constantly trying out new materials. Which materials are used has a lot to do with the robot's application. Obviously, strength is almost always important, but as we'll see throughout this book, there is a constant conflict in robot building between strength/durability versus power requirements.
