Tri-North Builders recently used a couple demolition robots for the demo at the Hilldale Mall in Madison, WI. These are remote controlled machines by Brokk.
Fitted with hydraulic breakers and other attachments, track-based, electrically powered demolition robots can venture into interiors, hazardous environments and confined spaces to dismantle floors, ceilings and wall slabs, keeping workers out of the way of falling concrete and other dangers.
