Summary
In this chapter, we discussed the importance of careful power system design for your Arduino robots, especially when using powerful rechargeable lithium batteries that have the potential to cause substantial damage by virtue of their immense power density and current capacity. We got to know the key components of a robot’s power system that can serve you well even in advanced and power-hungry robots. Not all Arduino robots need an elaborate power system, and the smallest ones can even run off USB power. But whenever you use powerful batteries in your robot designs, it is a good idea to spend some thought on a power system that makes your robot safe and reliable.
In the next chapter, we will learn how to give your robot the ability to express itself with LEDs, displays, and sound.
