I just looked. It varies a lot. They have an M0 processor for 93 cents and one of their M4 goes for $67. Prices are "all over the map". I think this is the effect of the current chip shortage. Some specific ICs are hard to get and expensive but some very similar ICs are cheap and which are cheap and which are expensive changes frequently.
But if I were designing a PCB for a robot. I'd simply design in a 40 pin socket for a Raspberry Pi Pico or maybe a Teensy and avoid the hard work of laying out a microcontroller and just use a common breakout board as if it were a huge IC. It greatly reduces the risk of an error and does not require much engineering skill.
