EXPO-LINE MAKES ROBOT LINEMARKING ACCESSIBLE FOR CLUBS!

Especially for clubs and organisations with a limited budget, Expo-Line (in collaboration with TinyMobileRobots) is coming up with a Robot Linemarker Sport. The Pro version is doing well with contractors and municipalities that are responsible for quickly lining up many fields at different locations. The new version should offer a solution for associations that only need to line a few fields on one complex.

In our pursuit of sports under the best possible conditions, "Create a brilliant Game". We have  continued to focus on our R&D in recent years. Due to our desire for quality and the ever new innovations that come onto the market for this purpose, the furnishing of sports facilities has become precision work. This also applies to drawing lines. The high occupancy rate at many sports parks leaves little time to implement this adequately. In many places, people are also dependent on volunteers, who are willing to commit themselves for many reasons, but on condition that it remains 'cosy & simple'. Delivering precision work under great time pressure is then sometimes difficult.

The Sport Robot Linemarker uses sonar to determine whether the track ahead is free of obstacles. That sonar always explores the track 2 meters ahead. If it turns out that there is an obstacle there, the robot comes to a standstill and both a text message and an audio signal are sent to the tablet. So the robot comes to a stop before it has even reached the obstacle. As soon as the field manager has removed that obstacle it will start again. Obstacles such as fixed targets are pre-programmed in the software; the robot then drives around them independently.

Empty, the robot weighs only 25 kg. This makes it easy to steer and manoeuvre. The robot has thin wheels, which are driven separately. The progress is recalculated almost 200 times every second. Bumps in the surface or other things that allow the robot to make unexpected movements do not affect the quality of the drawn line. The 200 calculations per second ensure that the robot compensates for this. However, the presence of the field manager remains desirable, because the robot only carries the amount of paint needed to draw lines on one field.

The introduction of the Sport Robot Line Marker does not mean that volunteers or fieldmanagers are no longer needed.
The opposite is true: the robot cannot function without supervision. The difference is that from now on the supervisor is only expected to maneuver the robot to the different fields and make sure that the robot gets a new can of paint with each field. For the rest it is waiting until the work has been done, or until the robot indicates that one has to come and have a look. The upgrade from executor to manager will be a welcome recognition for every volunteer.
