Here is a robotic bricklaying system designed to work collaboratively with the mason to lower costs and increase productivity. SAM100 (Semi-Automated Mason) performs repetitive task of lifting and placing each brick. According to Construction Robotics, this robot is controlled via a wireless handheld device. It can increase productivity of mason by 3-5x while reducing lifting effort by over 80%.
The above video shows how these bricklaying robots work. More information is available here.
