San Francisco Bay Area-based Diamond Age announced that it has raised $8 million to ramp up home construction with robot arms and 3D printing.Dolby Family Ventures, Calm Ventures, Gaingels, Towerview Ventures, GFA Venture Partners, and Suffolk Construction are among the investors in the seed round, which is led by Prime Movers Lab and Alpaca VC.The startup aims to put a slew of key emerging technologies to work in the service of building houses with fewer workers in a much shorter amount of time.Diamond Age asserts that once its technology is fully realised, it will be able to reduce manual human labour by 55% and reduce the time it takes to construct a single-family home from nine months to 30 days.A portion of the money will be used to set up the processes for building a 1,100 sq foot demonstration house as proof of concept.The company relies on robotic and 3D printing solutions in particular. The former entails a collection of 26 robotic arm attachments to aid in the construction process. The interior and exterior walls of the structure are built using this technology in conjunction with gantry-based 3D printing.The company is focusing on the housing shortage in its backyard, the Bay Area. Construction companies will be able to rent the systems through a Robotics as a Service(RaaS) rental model. The system's pricing details have yet to be revealed.Additive manufacturing, also known as 3D printing, is the process of creating a three-dimensional object from a CAD model or a digital 3D model.A robotic arm is a type of mechanical arm that performs functions similar to those of a human arm and is usually programmable. The arm can be the sum of the mechanism or part of a larger robot.The manipulator's links are connected by joints that allow for either rotational or translational movement. The manipulator's links can be thought of as a kinematic chain. The end effector, which is analogous to the human hand, is the end of the manipulator's kinematic chain. However, the term robotic hand is frequently used as a synonym for a robotic arm.Image Source
