I have been messing with our newly acquired PX4 Autonomy Developer Kit (MRB-D0011-4-V1-C20-M22-T7-K0) and it seems to me in the marketing that this drone is capable of SLAM. However, I am not able to get it to work as there is no TOF sensor on it and the voxl-mapper is asking for one. I pulled down the latest SDK 1.3. What I am asking, is the drone capable of SLAM using voxl-mapper with this setup?
