### Given an initial position, a goal position and a duration find a trajectory

I have an initial position $X^R_{init}$ of the robot ($x$, $y$ and yaw) and a goal position $X^R_{goal}$ I need to create a trajectory of duration $T$ with $n$ waypoints to move the robot from its ...
I have a differential drive robot, and it's supposed to drive on a parabolic function $(f(x) = x^2)$. But for all control algorithms, you have a trajectory given as $f(s)$ or $f(t)$. I want to use ...
