I just ordered a Core2-ROS. I have a tinker board in my spare parts bin. Now I have a use for the Tinker board! I was wondering if you sell the Rosbot aluminum chassis. I have most of the hardware necessary to build the Rosbot … everything except the LIDAR. My goal is to eventually scale the bot up to an outdoor platform with the capability of docking with an outdoor charger when power is low. I will also add GPS for outdoors along with geofence mapping the perimeter of my yard.
