This wiki describes and explains the software that was made for and implemented on the PICO robot to complete the retake of Embedded Motion Control course 2017-2018. The mission of the retake EMC 2018 is describe in the subsection ‘The challenge ‘Follow me!’’.

The robot that is used during the project is PICO. PICO has a holonomic wheelbase with which it can drive, a Laser Range Finder (LRF) from which it can gather information about the environment (blocked/free space) and wheels that are equipped with encoders to provide odometry data. All software that is developed has to be tested on the robot. There is also a simulator available which provides an exact copy of PICO’s functionalities. PICO itself has an on-board computer running Ubuntu 16.04. The programming language that is used during the course and the retake is C++ and Gitlab is used to store the cod

Initial Design

Introduction:

For the initial design, the requirements will be discussed as well as the functions and their specifications. Moreover, a list of the used hardware components and the diagram of the interface are shown below.


Requirements

  • Execute all tasks autonomously.
  • The POI will start initially close to and is detectable at standstill.
  • Finish the challenges within 2 minutes.
  • The POI will move in such manner that, in most cases, two legs are visible.
  • The POI will pass trough the middle of the target strips.
  • The PICO must cross 80% of the target strips.
  • The PICO must follow the POI at a distance of approximately 0.4 [m].
  • Perform all tasks without bumping with a person.
  • Perform all tasks without getting stuck in a loop.
