Kabir replied to Forrest Haller's discussion What are the standard CAN protocols that drones use?
"They were spec'ed for different purposes. CAN is a high speed onboard interconnect. MAVLink is an offboard interconnect, primarily designed to interface with a GCS or other MAVs."

Kabir replied to Forrest Haller's discussion What are the standard CAN protocols that drones use?
"The CAN specification has existed since the 90s. Not the UAVCAN protocol. Mavlink is pre-2009, from the original Pixhawk student team. UAVCAN came later."

Robust GPS-Agnostic Navigation - Visual Planning, Estimation and Control for MAVs

Posted on March 31, 2016 at 5:37pm 30 Comments

With all the talk of integrating drones into civilian airspace, there is need for better safety and GPS-agnostic navigation methods - visual navigation and obstacle avoidance is paramount to integrating drones (micro-aerial-vehicles, MAVs) into our cities and elsewhere, because…
