Robots are programmable machines capable of performing tasks normally performed by humans. They can be used in many different industries, such as manufacturing, medicine, logistics, or aerospace. Manipulators are mechanical devices designed to move or position materials. They are often used in manufacturing to grip, rotate or move workpieces. Bar loaders are devices used in CNC machining to automatically load bar stock into a lathe. This saves time and labor costs by eliminating the need to load bars by hand. Winders are machines designed to wind materials such as paper, plastic film or wire. They can be used in many different industries, such as the packaging industry or the electronics industry.
