Drone Guidance and Obstacle Avoidance

Drone Guidance and Obstacle Avoidance

UAV drone and obstacle avoidance

This on going project aims to design the guidance trajectory and obstacle avoidance capability of the drone. The first issues was that to obtain an autonomous drone, they should be equipped with maneuver capability especially when considering flying in urban and at low altitude. 

The are many factors to be research in this specific problem:

1. Guidance controller (simulation and experiment)

2. Sensor characteristics through experiment

Both of this problem has been addressed and the guidance for lateral movement has been obtained and tested. the flow for guidance and avoidance is shown is the following flowchart. 

 

By obtaining the controller of the drone, the lateral movement can be designed. The characteristic of the sensor in this experiment, we used LIDAR 360degree scanner, was used to estimated the distance error in order to perform decision for case by case condition.

The way forward for this research is to perform system integration of the guidance controller and sensors on the real hardware and tested on real obstacles.

and IP has been filed for the algorithm

Propeller Motor Performance Analysis

In this research we are concerned with the effect of combining multiple propeller and motor performance. The objective of this research is to find a mathematical correlation between motor constants, propeller sizing to get the optimum combination to fit a specific drone missions.

 

The next step will be to develop a software that include the specification of motor and propeller to fit a specific mission. A test rig to model the effect of thrust and torque to different angle of attack is also required to further integrate the features into a UAS system.

Credit goes to assitance resercher Ms Siti Mastura for conducting static testing of the propeller.

Development of VTOL UAS

 The objective of this project was to modify off the shelf drone to perform VTOL mission. In order to do that a conceptual design and analysis was done:

1.To develop a conceptual design of fixed wing VTOL UAV based on ready-to-fly (RTF) fixed wing UAV.

  1. To analyze the thrust performance of the fixed wing VTOL UAV in both, fixed wing and multirotor modes.

This is the flow chart for the research. In this first development, the thrust analysis was done to estimated the power required and available for the aircraft to perform VTOL. For the moment is focusing on the climbing phase. The next issue to perform is to obtain the aerodynamic derivatives in order to design the controller to perform transition.
