日建築工人短缺 請機器人來蓋樓

 Robots are entering the workforce to help bridge the labor shortage in Japan. In construction sites, robots are often used for night shifts when no human workers are available due to safety and regulatory concerns.
 Major Japanese construction company Shimizu Corp. showed off several robots, including one that picked up a big pile of boards and took them into an elevator. Robots have been improved to take over some of the welding, shipping, and basic tasks involved in constructing a new high rise. But even so, robot labor only makes up about 1 percent of each project, based on current technology. Robots are nowhere near perfect. Trying to raise the number to even 10 percent is a major challenge and might be too costly.
 Japan's construction sector is booming but contractors are struggling to fill labor shortages — a problem playing out in other parts of the world, including the U.S. There were about 3.4 million construction workers in Japan in 2014. That's expected to shrink to 2.2 million by 2025, according to Shimizu Corp.

 機器人逐漸進入日本職場,協助解決勞力短缺 的問題。在建築工地,機器人往往上夜班;因為 基於安全顧慮及法規考量,這段時間通常找不到 人力。
 日本知名建設公司清水最近展示了幾款機器人 ,其中一款機器人可以扛著一大疊木板進電梯。 機器人近來已慢慢改良,可以在興建大樓的工地 裡,擔任一些焊接、搬運等基本作業。即使如此 ,按照現有的技術,機器人在每個工地僅占1% 的勞動力。機器人距離完美還有一段長路要走, 若想把機器人的勞動力占比拉高到10%,將會是 極大的挑戰,而且成本可能很高。
 日本營建業景氣佳,但建築承包商苦於勞力短 缺,包括美國在內的其他國家也面臨相同問題。 根據清水建築的估計,2014 年日本約有340 萬 個建築工人,到2025 年之前,將下滑到只剩220 萬人。
