 To caculate Heading error we need to represent the position of the target point $G$ relative to robot frame coordinate ${B}$. We can do this by using homogenous coordinates and transformation matrix in 2D. Here we introduce $^I\tilde{P}_G$ and $^B\tilde{P}_G$ as homogenous coordinate notation of $^I{P}_G$ and $^B{P}_G$ respectively, where. $$ ^I\tilde{P}_G = \left( \begin{matrix} ^Ix_G\

Hello, This is just a simple introduction for anyone who stumbles upon this notes. As a liberal person, 'liber' is my favorite word. It means 'book', and also 'free'. So this note is a free book for everyone. Any soul can copy and distribute these notes for free. Spread the knowledge and illuminate the world! Trustworthy is the heart of this age of information. It is my motto to write an only honest record of my points or ideas in this libre. 'Normous' is a Swedish word that represents this spirit of mine. Enjoy! Best regards, Libre Normous
