Robotics, automation, sensors and data analytics to ease the work of cleaners in Singapore

The National Environment Agency (NEA) signed
Letters of Intent
(LOI) with seven INCUBATE partners today to officiate the
beginning of a series of trials that will be carried out at partners’ premises
over the next few years. INnovating and CUrating Better Automation and
Technologies for Environmental Services (INCUBATE) embodies the partnership
between the technology providers and services providers, premises owners, and
the government, to collectively innovate and curate better technologies,
solutions and innovations for the Environmental Services industry.

The signing ceremony was witnessed by Minister for the
Environment and Water Resources (MEWR), Mr. Masagos Zulkifli, and Mr. Albert
Chua, Permanent Secretary of MEWR, as senior representatives from each partner
organisation commemorated this partnership at the launch
event of the Environmental Services Industry Transformation Map

The list of organisations participating in the trial are: 1)
for Healthcare Assistive and Robotics Technology
(CHART), Changi General
Hospital; 2) Changi
Airport Group
; 2) City
Developments Limited
(a Singapore-listed international real estate
operating company); 3) NTUC Club (the
leisure and entertainment arm of the National Trades Union Congress, established
in 1986 to provide affordable lifestyle options for union members and the
public); 4) Robotics
Automation Centre of Excellence
(an industry initiative to drive industry
4.0 change within Singapore and Southeast Asia region); 5) Sports Hub; 6) The Esplanade
(a non-profit performance arts venue).

Through this partnership, the various stakeholders for the
private premises will be able to collaborate with NEA in identifying challenge
statements of common interest in the areas of environmental services and conducting
trials for technology, solutions and innovations to address challenge
statements, along with studying the feasibility of wide-scale adoption in their
respective premises.

The participating entities will share information with each
other and learnings from the trials and execute viable technologies, solutions
and innovations in their respective premises when ready.

One of the INCUBATE partners, the Changi Airport Group
(CAG), has been using
technology, automation and data analytics
in their cleaning and waste
management operations. For instance, CAG is testing customised ‘fill’ sensors
in some of its litter bins in T3. The sensors will alert cleaning staff when
the bins are full. CAG plans to retrofit 150 litter bins in T4 with these
‘fill’ sensors for the next stage of the trial. If successful, the deployment
of such bins will shift the clearing of the litter bins from a scheduled
approach to an on-demand one, freeing up cleaners’ time for other tasks.

Autonomous Cleaners are also being trialled at CAG. The
autonomous cleaning equipment (ACE) is a hard floor scrubber which can clean up
to 1,600 sqm/hr. It can avoid obstacles and map new floor areas quickly, to
make it more deployable to all the terminals. To ensure safety and security
during cleaning operations, the machine is equipped with real-time monitoring
and 24/7 remote manning service. To-date, the trial has completed approximately
1,500 cleaning hours and covered 1,500,000 sqm of hard floor (equivalent to
about 230 football fields).

The power-assisted janitor cart is being tested. It is a
battery-operated housekeeping cart designed to replace the conventional manual
one. The cart is battery-operated (speed of less than 5km/hr) to enhance the
mobility of the cleaner. It reduces cleaners’ fatigue and enhances performance
and productivity.

In addition, CAG is already using data analytics for toilet cleaning.
An Instant Feedback System (IFS) in the form of a small wall-mounted screen at
the exit of the toilets, it allows users to give feedback easily so that issues
in the toilet can be addressed quickly. CAG collates the data from the IFS and
analyses it to plan for service improvements.

Some other examples of the upcoming project opportunities
are as follows:
