Introduction aimed at mining the transportation of materials at construction sites "No preliminary setting on site" "Selectable for various construction workers"
1. Company Introduction
Maeda Construction Industry, which completes its 100 years in 2019, is engaged in contracting, planning, surveying, designing, construction, supervision and consulting of domestic and foreign civil engineering construction and other construction work in general as a major project.
Yoshiaki Yasui, General Manager, Product Research Innovation Laboratory, Technical Research Institute, commented on the issues before CarriRo was introduced as follows. "When the construction work is completed at the work site, we will move on to work at the next work site, but due to this nature that the site is not fixed, it was difficult to introduce stationary equipment, but recently the problem of human resources shortage has also occurred in the construction site, and although labor saving by automated equipment is a top proposition, it is not quite as a device that can be handled even in environments that are not necessarily on a well-maintained road like a construction site was."
As reasons for selecting CarriRo, he says, "In both Karugamo mode and Drive mode it is not necessary to prepare in advance at the work site so that it can be used immediately", "Because the operation method is very simple, it can be used by various construction workers" "It is possible to travel on some level difference, bumpy road, sloping road," and "the cost of introduction can be reduced".
About the effect after introduction, about 1 year has passed since the introduction of CarriRo, we can use it without problems even at the construction site as originally assumed. I am evaluating the fact that no force is required at all compared with the usual hand-operated trolleys that I have used in the past. In addition, I feel that workers at site work well with the robot like CarriRo, so that they can be aware of future automation.
For future developments, we have received requests from customers such as "we would like to carry heavier items" and "correspondence to outdoor driving". Moreover, we are expecting to realize the unmanned operation from the labor saving by autonomous mobile type CarriRo.
２． Business problem before CarriRo introduction
The construction industry will move to work on the next site once the work on site is completed. Due to the nature that the site is not fixed, it was difficult to introduce stationary equipment. Meanwhile, recent problems of talent shortage also occurred at construction sites, and labor saving by automated equipment is a top proposition, There were not many appliances that can be handled even in environments that are not necessarily maintained roads like construction sites.
３． Reason for introducing CarriRo
· In both Karugamo mode and Drive mode it doesn`t require any preparation beforehand · Since the operation method is very simple, it can be used by various workers · It is possible to travel on some level difference, bumpy road, sloping road · The introduction cost is reduced
４. Effect after introducing CarriRo
Approximately one year has passed since CarriRo introduction, but we have been able to use it without problems even at the construction site as originally expected. We are evaluating the fact that no force is required at all compared with the usual hand-operated trolleys that we used in the past. Moreover, we feel that field workers also have awareness towards future automation by touching a robot like CarriRo.
５． Next Deployment
In the verification so far, we have requested that we want to carry more heavy loads, we want to be able to drive outdoors, etc. These were our request to ZMP. We are hoping for suggestions and developments that will make these requests fulfilled. We are also expecting to realize "labor saving" from "autonomous mobile CarriRo" to "unmanned".
