After a 72-hour hackathon arranged by Volvo, a group from Halmstad University won the Best Build Team award with its smartphone prototype app Intelligent Probe.
– We created a smartphone app for automatic inspection of the undercarriage system of excavators. By using the smartphone camera, pictures of various excavator parts are analysed through computer vision methods to measure sizes of, for instance, steel shoe and rolling bodies in the undercarriage system. The analyse will for example determine the need for repair and can reduce the workload of Volvo Technicians, says one of the winning team members Eren Erdal Aksoy.
The competition was organised by Volvo Construction Equipment and Volvo Group Connected Solutions and took place in Gothenburg, November 23–26. Sixteen international teams competed in using image intelligence to solve existing problems for heavy equipment and machines. The Halmstad University team from the School of Information Technology consisted of PhD students Maytheewat Aramrattana, Yuantao Fan and Hassan Nemati, and Assistant Professors Sepideh Pashami and Eren Erdal Aksoy.
Volvo Construction Equipment is now further analysing the potential of the provided app prototype. There are also some ongoing negotiations between the winning teams.
– We received an invitation to collaborate with two other winning teams in order to extend the prototype and make a more comprehensive demo in the coming Bauma fair in April 2019, which is the world's largest machinery and construction equipment trade fair, says Eren Erdal Aksoy.
There were 220 international applicants to the VOLVO x HACK SPRINT, and 80 were selected for the competition. In total there were 16 teams from various countries such as Japan, UK, France, Ukraine, and Sweden. The judging was based on five criteria: Technical Innovation, Execution, Creativity, User Experience, and Pitch. Awards were given for Best Hack (awarded to the team that solved the real-world problem the best), Best Build (awarded to the team that built the most deployable solution), and Honorable Mention. Halmstad University received the Best Build Award for its app Intelligent Probe.
The smartphone app shows the template drawing of different components to guide the technician.
Developed computer vision solution detects various features on the excavator. Once the technician approaches enough, the app starts detecting the borders of the shoe plate and returns the height.
