We are Ubiquity Robotics, a community project to create ROS based robot platforms, meet us at ROSCon 2017 in Vancouver.
Our main platform is Magni - a ROS platform that has a 100kg payload capacity. It is designed to be a extensible jumpstart point for you to develop you own robot applications using ROS. See it in person at ROSCon.
