34 | The Future of Robotics Texas Instruments Solution 3 Control Systems. Although each of the solutions above provides customizable designed-in prevention measures for surges and overvoltage, control systems use microprocessors and sensors to regulate power flow once the system is operating. Microprocessors process data and conduct the majority of computational functions that industrial robots perform. They also act as the hub connecting the related equipment the robot uses to execute a task. Other microprocessor functions can include running internal diagnostics and sensor data collection. Industrial robot sensors continuously provide real-time feedback on the robot's position. These sensors also help generate diagnostic and performance data needed for the microprocessor to analyze and determine the robot's health or help predict premature mechanical or electrical failures. The control systems work in tandem to process the data to enable engineers to optimize the equipment settings and procedures when the robots operate while providing engineers valuable insight into metrics that could point to a safety hazard. Power Hazards Like how external power surges and shortfalls can lead to accidents during operation, disruption to some or all of the robot's power supply might also create hazards. For a threat arising because of excess current, the industrial robot's controller might become damaged. With a malfunctioning controller, extra power reaches the downstream components, leading to equipment failure, electrical fires, or shock. Multiple forms of power can feasibly propel industrial robots. Hydraulic, pneumatic, and electrical sources are three prevalent choices. Because of improved control, engineers typically employ AC and DC electric power to industrial robots. In particular, design engineers performing motion-driven action tasks enjoy increased motion control over the robots in operation. In the event of a hazard or accident, the robot can be rapidly stopped or powered down for maintenance. These Texas Instruments products provide idea answers for electrical safety in industrial robots by creating products that can adapt to their application, level of integration, and control methodology. Outcomes of Incorporating Safety Features for Robots Although the operational safety features can disrupt the current procedure and equipment, implementing these tools provides the facility with positive outcomes in terms of robot lifespan, consistent performance, and lower operating and maintenance costs. Longer Life Tools such as the Texas Instruments eFuses protect the industrial robot equipment from surge and overvoltage events. These solutions maintain performance within a desired operating range a higher percentage of the time. Reducing or eliminating these events decreases part fatigue, which increases the life of the equipment. With the high cost of capital, the robot spends more time within its desired operating range. Improved Reliability In addition to providing surge and overvoltage protection, smart high-side switches compile constant diagnostics. Engineers use this data to develop predictive models of the robot's performance and expected fatigue. The larger the data set collected, the higher the likelihood that the safeguards will identify a potential operational hazard. This diagnosis will help to avoid a system shutdown. The diagnostics also help determine where the customizable current limit value should be, optimizing the industrial robot's performance for the target range. Lower Operating and Maintenance Costs Operating and maintenance costs decrease accordingly as the industrial robot operates more reliably and is optimized for performance. Downtime increases operating costs as the asset sits idle during a repair. Without safeguards to protect the equipment, there will be a higher frequency of maintenance. Safeguards are critical for industrial robots, as they are for humans. " "
