We currently use demolition robots to perform more specialised demolition. There are a plethora of advantages of using robotic demolition to other older methods.
As the operator can remain distant from the work, the machine can work in an isolation zone so there is no risk of injury for any involved.
Robots are more compact and powerful than larger machines such as excavators and thus can be transported into areas where works would normally have to be done by Demolition Labourers.
As they are powered electrically, robots can be used in areas where emissions are a concern.
