Thanks to You and Pierre @khancyr for this great upgrade of the Rover project.
This wiki is also very helpfull to get us started with wheel encoder odometry.
ROVER is like ''going back to the root'' in order to master and implement advanced autonomous robotic systems.
State of the art Odometry, Localisation and Mapping is much easier and cheaper to implement on a ground based vehicle. Thanks to ROS , it is possible to build a fully autonomous, self-guided vehicle using SLAM on a budget. Mastering these advanced concepts on a platform that can ''stop and wait'' for hours , while we proceed to modification and optimisation is a feature that really gives a clear advantage of a ground based vehicle.
The other advantage, on the short term, is the fact that weight and power is less limitative than on a flying vehicle, allowing to have bigger-sized onboard Companion Computers , like MINI PC or Laptops, easing the entry level to a broader range of experimenters.
Cant wait to try it on my new DIY Diff-Drive Rover
