Adaptive solver for stiff systems of ODEs using semi-implicit Runge-Kutta method of third order

a simple differential array using XMOS 6+1 board

DiffBot is an autonomous 2wd differential drive robot using ROS Noetic on a Raspberry Pi 4 B. With its SLAMTEC Lidar and the ROS Control hardware interface it's capable of navigating in an environment using the ROS Navigation stack and making use of SLAM algorithms to create maps of unknown environments.
