DeepX, Inc. (Headquarters: Bunkyo-ku, Tokyo, CEO: Kaoru Nasuno, hereinafter DeepX) and Tadano Ltd. (Headquaters: Takamatsu City, Kagawa Prefecture, President: Toshiaki Ujiie, hereinafter Tadano) have released the progress of a joint research project of crane automation utilizing AI technology.
■Background and purpose of this project
Cranes are general purpose lifting equipment that are widely used in construction industries. Crane operators must operate multiple levers simultaneously while checking the position of the load visually. In addition, cranes are affected by the boom deflection and wind, so it takes a long time to become a proficient crane operator. On the other hand, the number of skilled crane operators in Japan is declining due to the aging population.The aim of this joint R&D project is to improve safety at work sites by simplifying and automating mobile crane operation by utilizing AI technologies.

■Why crane automation is difficult and what approach we took
Mobile cranes are known to be one of the most difficult machines to operate in construction sites. Slewing and elevating motion in mobile cranes typically generates undesirable two-dimensional load-sway; therefore, crane operators must be highly skilled to suppress this sway upon completion of the point-to-point crane maneuver.DeepX and Tadano have therefore developed a control algorithm based on AI technology. Using this algorithm, we can safely and accurately move the load to desired position while suppressing load sway. What makes this approach unique is the fact that rather than conducting rigorous system identification of the real crane, we leveraged the simulator environment to optimize the controller.
●Introduction movie of DeepX’s crane automation project
Within this joint project, we have achieved “automated point-to-point maneuver while suppressing the load sway”. DeepX will continue to work with Tadano to challenge more complex operations and further advance the technology for mobile crane automation. We will also aim to apply this technology on various types of cranes in a wide range of industries.
DeepX is an AI startup which has its roots in the Matsuo Laboratory at the University of Tokyo with the mission of “Automating Any Machine and Innovating Global Industries”. By automating any kind of machine and promoting automation of a wide range of manual work using various technologies including AI, DeepX aims to solve problems such as labor and skilled worker shortages as well as excessive staff workloads, which are significant challenges to many industries.
