Instead of giving the dangerous duty of cutting subterranean electrical wires to people, robots may be utilized.
# step the simulation through one time intervaldef step( self ):dt = self.dt# step all the robotsfor robot in self.robots:# step robot motionrobot.step_motion( dt )# apply physics interactions self.physics.apply_physics() # NOTE: The supervisors must run last to ensure they are observing the "current" world # step all of the supervisors for supervisor in self.supervisors: supervisor.step( dt ) # increment world timeself.world_time += dt
Robotics has a vital role in enhancing safety. Instead of placing individuals in danger, for example, remotely operated, wireless underground cable cutters may be utilized.
7. Drones
Drones will have a significant presence in the year 2020. There's no way the entertainment business could use it any more. However, by 2021, the usage of drones will have broadened significantly. Drones will be useful in the construction business, in addition to filming elegant Instagram videos or music videos. When utilized properly, they can prevent five out of every ten accidents on the worksite.
In the electrical engineering sector, this offers much-needed safety. Drones are now increasingly being used to assist record, gather, and analyse data on the job site, resulting in increased production and efficiency.
8. Electric Vehicles
Tesla, one of the world's most well-known electric car manufacturers, has seen its stock price surge since the beginning of this year. This comes after the firm surpassed the $100 billion mark!
This means that electric vehicles are on the verge of taking control. Experts predict that over 100 million electric vehicles will be on the road in ten years. Many investments are being made in electric vehicle technology, which will witness significant changes by 2021.
According to experts, approximately 125 million electric vehicles will be on the road by 2030. Given the millions of electric vehicles currently on the road, this isn't exactly a long-short situation. Consumers should anticipate stronger batteries, improved charging technology, more accurate autonomous driving, solar-powered EVs, and even electric planes from several EV makers.
9. Sustainable energy
Because of the large imbalance between need and supply in the foreseeable future in India, current patterns in electrical energy supply and demand are unsustainable. Exploiting energy-saving and aggressive usage of renewable energy systems is the road to sustainability.
The need for renewable energy sources is at an all-time high. The use of utility-scale renewable fuels like solar, wind, and hydropower is at an all-time high all across the world.
