Background:
Mobile robots are often used in industry to transport items around warehouses and to
transport parts between different areas. In your robotics lab tour, you were shown a
particular robot called the robot called the ‘Robotino’. Some images of the Robotino are
shown in Figures 2 and 3.

The Robotino is an omnidirectional robot (a Swedish wheeled robot), which is used in our
lab to transport mobile phone parts between two industry 4.0 stations. This means that the
two stations do not need to be physically connected to each other as the robot is able to
transport parts between them. A floor plan of the lab and the two Industry 4.0 stations is
given below:
In the Figure 3, it can be seen that there are 3 main points that the robot must visit which
are labelled from A to C. The robot’s initial position is located at point A (the robot’s
charging station). The robot then travels from point A to point B where it collects some
mobile phone parts from Industry 4.0 Station 1. To do this, it must stop at point B for 5
seconds in order for the parts to be loaded. The robot then travels to point C to unload the
parts onto Industry 4.0 Station 2. Again, the robot must stop at point C for 5 seconds in
order to offload the parts. Once it has done this, the robot returns to its charging station
and the process is completed.
In order for the parts to be loaded and unloaded, the robot must be facing the Industry 4.0
stations (its heading direction must be pointing towards the station). On the other hand, to
dock with the charging station the robot must be facing away from the charging station as
its charging port is located on the rear of the robot. In total, the process is given as follows:
Figure 3: The lab floor plan. The red circles labelled from A to C are points that the robot must visit.
1. The robot’s initial position is at point A, with its initial heading direction facing away
from the charging station.
2. The robot travels from point A to point B, by the time the robot reaches point B, its
heading direction should be pointing towards the Industry 4.0 Station.
3. The robot waits at point B for 5 seconds.
4. The robot travels from point B to point C, its heading direction should still be
pointing towards the Industry 4.0 Station.
5. The robot waits at point C for 5 seconds.
