of traffic on roads and translate words from one language to another. Materials used to make robots: aluminum and steel are the most common metals. Aluminum is a softer metal and is therefore easier to work with. Steel is several times stronger.
Due to the inherent strength of metal, robot bodies can be made using sheet, bar, rod, channel, and other shapes. Robots have many advantages in various applications but also have several disadvantages. In outer space robots are used for exploring stars, planets etc., investigation of the mineralogy of the rocks and soils on Mars, analysis of elements found in rocks and soils. Household robots are used as vacuum cleaners, floor cleaners, gutter cleaners, lawn mowing, pool cleaning, and to open and close doors.
Industrial Robots are used for welding, cutting, robotic water jet cutting, robotic laser cutting, lifting, sorting, bending, manufacturing, assembling, packing, transport, handling hazardous materials like nuclear waste, weaponry, laboratory research, mass production of consumer and industrial goods. Nano-robots are being developed to be in the blood stream to perform small surgical procedures, to fight against bacteria, repairing individual cell in the body. The development in medical field has been proportional to the evolution of physics. The recent medical technology includes virtual reality, precision medicine, health wearables, artificial organs, 3D printing, wireless brain sensors, robotic surgery, smart inhalers.
Particle physics deals with fundamental particles of nature. Protons and neutrons are made of quarks. Cosmology is the branch that involves the origin and evolution of the universe. Accelerated mass emits gravitational waves which are very weak.
Black holes are the strongest source of gravitational waves. - - - - Unit Recent developments in physics Recent developments in Physics A few areas as examples Technology Robotics Science Black holes Gravitational waves Nanoscience & Nanotechnology Medical diagnosis and therapy Particle physics Cosmology Medicine Inventions in physics & Developments in Medical science Recent medical technology Nanoscience, Nanotechnology, Nanoparticles Interdisciplinary- nanotechnology Nano in nature Early beginning & development Nano in laboratories Components Types Applications Materials used to make Robots Advantages & Disadvantages Applications of nanotechnology
