What Is RPA?
Robotic Process Automation (RPA) uses software robots (“bots”) to automate repetitive tasks by mimicking human interactions with applications. RPA bots operate at the UI level – clicking buttons, filling forms, copying data between systems, reading screens, and navigating menus – without requiring changes to the underlying applications.
Modern RPA extends beyond simple screen recording into intelligent automation: optical character recognition (OCR), intelligent document processing (IDP), process mining to discover automation candidates, task mining to record user workflows, and AI/ML models that handle unstructured data and make decisions. RPA platforms now orchestrate fleets of bots across the enterprise, scheduling unattended runs, managing credentials, handling exceptions, and escalating to humans when needed.
RPA fills the gap where API integration is unavailable or impractical – legacy mainframes, desktop applications without APIs, Citrix environments, and cross-system workflows that span dozens of applications with no common integration layer.
