Construction: widely used in such industries to perform simple repetitive tasks, and in industries where work must be performed in environments hazardous to humans. OR Medical: robot-assisted surgery gives the surgeon better control over the instruments and a better view, because of this, surgeons don’t have to stand all of the time during the surgery and do not get tired as quickly.

Importance in the future(2 marks) For construction In the future: Construction is an inherently dangerous job.

Robots can improve worker safety in construction environments by taking over some of the more dangerous tasks and allowing human workers to complete more cognitive tasks. help eliminate a lot of the stress and damage that occurs to a body during physical labor too. 3D-printing robots, will change the current makeup and are able to do on-demand and custom development projects. Being able to print prefabricated parts or components on site helps eliminate the need to transport large goods or materials.

Medical field: Robotic surgery is deemed by and large safer than open surgery.

The hospital stay is shorter, reducing the risk of infection; pain and discomfort is reduced; recovery time is faster; and blood loss and transfusions are lessened EXAMPLE 2 Name & describe the discovery( 2 mark) transmission and detection of communication signals consisting of electromagnetic waves that travel through the air in a straight line or by reflection from a communications satellite.

Function/Importance ( 1 mark) Electromagnetic radiation includes light as well as radio waves, and the two have many properties in common example police and fire department dispatches to aircraft communication, two-way radio communication works to ensure public safety Importance in the future(2 marks)

The biggest innovations have been in the world of communications. WiFi has been able to allow for quicker transmission of voice and information. Information technology and voice over internet protocol, has certainly seen the benefits of these new radio technologies. Better WiFi and the better and quicker that data and information can be transferred, the better that these future IoT products will become.
