A recent report by Markets and Markets estimated the growth of construction robots by at least 200 percent by 2023. This is the result of the growing demand and supply of artificial intelligence and robotics.
The construction robot market is expected to double from $76.6 million in 2018 to $166.4 million by 2023. The rise of the market is due to factors such as enhanced productivity, improved quality, and better safety with the implementation of robotics. Another reason behind the growing trend is global urbanization.
Construction robots that share the market are divided into three main types:
1. Traditional: These robots cover the majority of the market across a wide range of industries including vehicles. The most common forms of traditional construction robots include semi-autonomous excavators and backhoes. In order for these vehicles to work at construction sites, their software would retrieve the 3D maps of the sites and get instruction on how to operate within the area.
2. Robotic Arms: These robots have the ability to perform demanding, monotonous tasks at a rapid pace. One example is the semi-automated mason that can lay between 300 and 400 bricks per hour, compared to the 60 to 75 bricks per hour done by a human. Still, a human needs to operate the machine, it must be loaded with bricks, and it should not contain any excess mortar.
3. Exoskeletons: These robots are wearable suits that enhance the physical capabilities of the wearer. Robotic exoskeletons can either be active or passive, depending on the presence of a motor. Passive exoskeletons are commonly used in constructions because of their cost-efficiency and lighter weight, compared to active ones. Also, passive robotic suits may be used throughout the day.
While the report mentioned the three types of construction robots, the authors did not include robotic drones. Robotic drones have been gaining popularity in recent years and are very useful in surveying construction sites.
