I´m an automation engineer on my fourth and last semester at UCL Erhvervsakademi & Professionshøjskole. At my internship at Nordbo Robotics I have been working with the Nordbo Cube and Nordbo Force-Torque sensor.
Throughout my internship I have been able to get all the support I needed from the employees at Nordbo Robotics. I was given the time to learn all skills needed for the project to operate the Nordbo Cube and to add features to the robot program. Some interns feel
that their projects aren’t valuated at the company they’re working, but at Nordbo Robotics the project had their interest from start to end.
The Nordbo Cube is an end of line packaging concept using a delta robot, a vision system and two conveyor belts to move the products and their packaging. The Cubeis
completely encapsulated,making it impossible for a person to get hurt by the robot movements when operational.
The project goal of my internship was to manipulate the robot movements (Acceleration and deceleration) based on the weight of the product that the robot was moving. To be enable the weight measurement we mounted a 6 axis Force-Torque sensor between the end of robot arms and the gripper. We then made some changes to the program controlling the robot. One of these was a feature that made it possible to log the selected values from the
sensor to a csv-file, making it possible to evaluate the results later in the project.
We performed many tests with cans of mackerel and after each test, weight measured
with our Force-Torque sensor was compared with the actual weight of the cans. The first
tests didn’t create the best results, which led to minor changes in the programming. The
last test however showed great results, and the weight measured with the Force-Torque
sensor only differed by 10% while the robot was in motion.
