Automations and robotics

Automations and robotics refer to the use of technology to automate and perform tasks that were previously done by humans. Automation involves the use of software, machines, and other systems to perform tasks without human intervention. Robotics, on the other hand, involves the design and development of machines that can perform tasks autonomously or with limited human intervention. Automations and robotics are widely used in industries such as manufacturing, healthcare, transportation, and agriculture. In manufacturing, robots are used to perform repetitive and dangerous tasks, such as welding and painting. In healthcare, robots are used to perform surgeries and assist patients with mobility issues. In transportation, automated systems are used to control traffic flow and ensure the safety of drivers and passengers. In agriculture, robots are used to plant and harvest crops, reducing the need for manual labor. Advancements in technology have led to the development of more sophisticate...
