calibration
these are indoor estimation, but how about out door situations?
imu for the position transformation?
laser or camera for angle and distance measurement?
This is SLAM!!!!
To learn more about how we use the Multi-Sensor Unscented Kalman Filter, and how we build 3-D maps, please see sections 5.2 and 3.3 of the following thesis:

But as you see from these pictures, as the vehicle manuevers at high speeds and exhibits roll and pitch angles far away from zero, these kinds of controllers are not likely to work.

inertia is small
To learn more about how we use the nonlinear controller and how we plan three dimensional trajectories, please see the relevant chapters in the thesis below.

3D printing????? by drones???
considering payloads
