A Dutch robotics firm based final 12 months has seen its concrete drilling robots put into lively use on two main initiatives lately.
BauBot Companies, a subsidiary of worldwide fastenings specialist Fischer, has lately deployed its autonomous robots to drill almost 9,000 holes within the concrete lining of the Engelberg Base Tunnel, a busy motorway tunnel in Baden-Wurttemberg, Germany that’s being rehabilitated.
In addition they drilled almost 5,000 holes within the ceiling of an condominium block going up in Utrecht, the Netherlands for a suspended ceiling.
The corporate says the system is quick, exact, and takes a tough job that dangers Hand-Arm Vibration Syndrome (HAVS) off staff.
The BauBot system was used to drill holes to arrange for brand spanking new metal reinforcement forward of the set up of precast concrete components.
The robots drilled 8,960 holes over six months, every gap measuring 20mm in diameter and 220mm in depth, situated at various heights alongside the tunnel wall.
BauBot factors out that people can solely drill for 90 minutes a day to mitigate towards HAVS.
Working eight-hour shifts, the robots changed a 5-person crew and minimize the necessity for surveyors at each stage.
The system was capable of drill 48 holes from a single place.
In Utrecht, the system was deployed on a brand new condominium constructing within the under-development Cartesius city district.
Right here, two BauBot robots hammer-drilled 4,800 holes within the concrete for rods to carry up a suspended ceiling.
Every gap was precisely 6mm in diameter and 50mm deep.
The system extracts mud because it goes, and information knowledge from every gap drilled, together with depth and rebar hits.
The drilling occurred 20m above floor on scaffolding.
“The BauBots’ motion was restricted, and the construction had a fancy geometry that required cautious load distribution. Regardless of this, our BauBots carried out excellently,” mentioned Emil Kral, managing director of Fischer BauBot Companies.
