The Robot That Carries Out Site Inspections

DOXEL, a California-based startup, has created robots that can carry out building site inspections and analyse the data obtained, before passing reports back to project teams.

The firm's engineers have created two prototypes; a rover for internal inspection, and a drone for external surveillance.

The machines are equipped with high definition cameras and “Light Imaging, Detection and Ranging” (LIDAR) sensors - similar to those used by autonomous vehicles.

"Deep learning algorithms" - which enable the machines to process and evaluate the vast quantities of data captured on site - are used to compile reports on the progress of the work.

As shown in the demonstration video, Doxel’s robots are able to compare survey results with the data from building information models. This allows them to create analyses relating to cost (the 5D aspect of information modelling) and time planning (the 4D element), comparing as-built and model data.

In theory, the reports provided can enable early detection of delays or errors during the construction process, and to help eliminate cost overruns further down the line.

Although it is not yet known when Doxel’s products will be commercially available, the company hopes that its latest round of fundraising - which brought in USD $4.5 million - will bring the service to potential customers in the near future.
