Robots Have Been an Essential Part of the Production Process for High Volume Goods for a Very Long Time

However, when there is a non-standard working environment, where it has to deal with many different materials, shapes, context specific tasks, it did not have any economic value to introduce too much automation and therefore the work was done manually.

That's why robots are becoming smart now: Easy to use, flexible in handling, sensitive to their working environment and quickly learning on tasks! Not only are robots increase in functionality they are also becoming easier to operate.

The world of robotic solutions is facing major change as advanced electronic components for e.g. power supply, motion control, and sensing, support a quicker hardware ramp-up and create room for the development of differentiating software algorithms or new use cases.

All this wouldn't be possible without semiconductor solutions. Whether in an industrial robot, a cobot or an automated guided vehicle (AGV), intelligent semiconductors are the key enabler for all major robotic functions, from sensing and motion control to functional safety to security. Infineon's product portfolio checks all those boxes of a modern robot system making us your one-stop shop for robotic solutions.

A few of these applications will be highlighted in the following sections.

Efficient/Compact Servo Motor Drives

Motor drives transform the control signal from the motion controller into electrical energy that is provided to servo motors. Newer intelligent motor drives can close the position and velocity loops internally leading to a more accurate and more powerful motor control.

Infineon's chip and integration technology enables the motor drives to leave the external cabinet and connect directly to the motors within each individual axis of the robot. Instead of having 3-phase supplies for individual motors only a common DC-bus connection is required. By also integrating a power line communication solution, even a separate communication bus could be avoided. Within a moving robot-arm the wiring efforts can be reduced from 27+ down to two.

Below we would like to recommend the Infineon components for an efficient compact servo motor drive:

Efficient/Compact Power Supplies & Chargers

The power supply of the robot provides energy for all the robot actions. The big challenge in this area is that the robots have often many axes requiring multiple power supplies operating in parallel providing different voltages.

Next to supplying DC voltage for the commonly shared DC bus, rectifier stages have to generate different auxiliary supply voltages for controls, drives, brakes, and other components. Therefore the central rectifier power must exceed the nominal power consumption of all components in use. The main difference between an AGV charger system and one for regular electric vehicles lies in the power classes used which is way smaller for AGVs and lies in the range of several kW.

The most general overview on a charger system can be seen in the block diagram below.

Condition Monitoring/Predictive Maintenance

One core IP of each robot system is the sensors that are being used to depict the robot's condition and environment as precisely as possible. This is essential for both performance and safety.

The robot has to be aware of the exact positioning, shape and texture of the work piece, residual equipment and its own peripherals. Non-invasive sensing of system parameters for the assessment of system states as well as the preprocessing of data and proactive reporting of deviation from known good state help to prevent system errors and enhance run-time of machinery. Thus, Infineon's solutions make existing machinery Industry 4.0 compliant.
