An autonomous mobile robot has been seen moving around the corridors of the REDI shopping centre in Kalasatama, a neighbourhood in Helsinki. Operated by Omron’s solution partner, Dimalog, the robot was taking part in a month-long ‘Home on Demand’ automated courier service trial, testing the potential for using autonomous robots for deliveries to urban homes. As part of a larger experiment called the ‘New solutions in city logistics’ project, which is investigating possible options for last mile deliveries in Finnish cities, it’s looking for solutions that will organise urban logistics as sustainably and efficiently as possible.
The trial was arranged by Forum Virium, the City of Helsinki’s development company, in conjunction with construction company SRV. Other organisations involved in the project include elevator company Kone; the K-Supermarket in the REDI shopping centre; Asumi, a digital resident service platform; and the design studio, Muotohiomo. For the trial, the mobile robot was programmed to deliver items of food from the shopping centre to apartments in the nearby Majakka tower block.
Refining the robot
Omron, Dimalog and Muotohiomo worked closely together to refine the operation and design of the robot to meet the specific needs of the project. To move around successfully, the robot had to navigate the supermarket and tower block corridors as well as using elevators and service tunnels. As it moved, the robot both whistled and talked in Finnish (using a speech synthesiser).
Lotta Toivonen, development manager for Housing Services at SRV (which built both the shopping centre and the Majakka tower block), comments: “The idea of whistling is that it’s a funny thing. On the other hand, people realise that the robot is coming. It speaks a bit, and people greet it. It is treated as if it was a person.”
Kaisa Spilling of Forum Virium adds: “It’s been fun to see how people along the way feel like it’s human. It might say in the elevator: ‘I’m sorry I would like to get out here’ or ‘Oops, this elevator is full. I’ll take the next one.’”
Running the trial
So, how did the trial work? Each delivery started with the receipt of an online order from a customer using the Asumi platform. Orders could also be placed through the supermarket by the shopping centre’s smaller businesses. The items (mainly meals) would be collected at the supermarket and loaded by staff into the robot, which would then deliver the order to the relevant business or apartment. The customer would receive an automatic notification as soon as the robot delivered the item.
Spilling remarks: “During the coronavirus epidemic, the robot brought lunches to homeworkers. Lunchtime was always fully booked.”
Throughout the trial, the robot could request an elevator itself, but needed an escort to open any doors that might have to be kept closed due to fire safety regulations. The escort was a university service design student, who reported any problems encountered by the robot and observed its interaction with people.
Self-navigating robots
The robot used on the trial was an Omron LD model – a self-navigating autonomous mobile robot (AMR). Unlike traditional autonomously guided vehicles (AGVs), mobile robots don’t need any expensive modifications to facilities (such as floor magnets or navigational beacons). They navigate by the natural features of the facility, having been designed to move material within challenging environments that might include confined passageways, as well as locations where there might be people moving around. Omron’s software also integrates with a company’s other systems so that the robots can become operational in minimal time.
Esa Korhonen, area sales manager, Omron Finland, explains: “Our mobile robots can dramatically boost the productivity of logistics operations. They navigate effectively and provide invaluable support to human workers, enabling employees to focus on other tasks that require complex human skills.”
Spilling concludes: “We are looking for new agile logistics solutions in the city. We are exploring how we could improve the smoothness of everyday life in the future. Robotics is essentially related to a smooth everyday life.”
