Popis:The subject of the work, in general, is convenient both for BSc/MSc projects/thesis. An appropriate work plan will be prepared according to the student’s degree and background.

The aim is to implement a cooperative control technique for the formation control of multiple mobile robots, which exist at the Intelligent and Mobile Robotics (IMR) laboratory in CIIRC-CVUT. The robots (TurtleBot), which are differential drive (unicycle type), are able to communicate with each other via a wireless protocol, and the linear velocity and heading angle of the robots are measured by their own sensors. The displacements of the robots with respect to each other will be measured by the industrial cameras. The first goal is to ensure the movement of the robots on x-y plane forming a pre-determined shape such as triangle, line, circular or V-shape. The appropriate consensus algorithm will be performed via simulations first, and then it will be implemented on the physical system. After that stage, flocking with obstacle avoidance using the measurement with LIDAR sensors will be studied and implemented.

Experience in programming with ROS and Python or C++ and in Matlab Simulink would be advantageous, as well as the experience in robotic applications, e.g. using industrial cameras and LIDAR.

Pokyny:1- Get acquainted with the TurtleBot (TB) [1].
2- Study the kinematic model of the unicycle type robots and the control design based on feedback linearization [2,3].
3- Drive the robot along a predetermined path using TB’s odometry data.
4- Get acquainted with formation control approaches. Focus on displacement-based formation control [4].
5- Integrate the industrial cameras to the TBs to measure the displacements between the TBs.
6- Implement the cooperative control algorithm for two TBs following a leader TB while keeping line (and triangular) formation [5-7].
7- Apply formation scaling/transition strategies with respect to obstacles and passages to be passed [4].
