The potential of autonomous and connected sweepers for smart and sustainable cities

The objective of this research was to evaluate the potential of autonomous and connected sweepers
for cleaning pavements and cycle ways. Supported by sustainable policies, the networks of cycle ways
are growing considerably outside cities, and their maintenance is demanding in terms of economic
resources. The current study examines the idea of replacing manned service vehicles by autonomous
sweepers in urban areas. Autonomous sweepers could be operated from a control room to perform
planned and on-demand cleaning tasks. Tests were carried out with the S100N Spring developed by the
Chinese company Idriverplus Technology Co., Ltd. The sweeper performance and efficiency have been
evaluated (1) with gravel, leaves, pine cones and rubbish in a closed test area and (2) in real conditions,
on two pavements in Kongsberg (Norway). The results from the cleaning tests and the interactions with
vulnerable road users are presented. Challenges and limitations of the technology are discussed.
