Installing and using singleshot6DPose

Hello! So this time I will be installing and trying to use singleshot6DPose. This is an state-of-the-art neural network for object pose detection using RGB images. It is based on YOLO so its superfast. I am starting with a system as follows: Ubuntu 16.04LTS Cuda compilation tools, release 9.2, V9.2.148 Python 3.5.2 Nvidia GeForce 1050 …

3D Quadrotor: LQR Controller for the non linear model (using differential-flatness property)

1) Proof of differential flatness for 3D quadrotor 2) LQR Controller 3) In the previous post, I derive the proof of differential flatness for the basic model of a quadrotor. With the equations developed in that post, it is possible to compute trajectories for all the states and inputs so that a quadrotor moves from …
