Robots
A robot is a deterministic worker that follows a fixed workflow.
Tasks
- Execute predefined steps
- Perform UI clicks, type, extract data
- Call APIs, read files
- Handle structured repetitive actions
- Require explicit workflow design
- Do not generate their own steps
- Do not make decisions unless pre-programmed
Robots = “Automate the known”
They do exactly what you tell them, nothing more.
Example
A robot reads an invoice → enters into SAP → emails confirmation.
If the vendor number is missing? Robot fails.
AI Agent
An AI agent is a more autonomous entity that uses LLMs + reasoning + tools to achieve goals, not just follow scripted tasks.
Tasks
- Understand goals in natural language
- Break work into subtasks
- Decide which tools (robots, APIs, apps) to use
- Change execution plans dynamically
- Recover from unexpected situations
- Learn from interactions
Agents = “Automate the unknown”
They deal with variability and unstructured work that robots cannot.
Example
Agent receives: “Process this vendor invoice.”
Agent:
- Reads document
- Recognizes missing vendor ID
- Searches in ERP
- If still missing, drafts an email asking AP team
- Once confirmed, instructs a robot to complete SAP entry
- Logs the case
Agents solve end-to-end business problems, not tasks.
Robots vs AI Agents
| Feature | Robots | AI Agents |
|---|---|---|
| Execution | Deterministic workflow | Goal-driven, dynamic |
| Behavior | Follows strict steps | Chooses steps autonomously |
| Flexibility | Low | Very high |
| Handles edge cases | Only if pre-programmed | Can reason and adapt |
| Inputs | Structured (files, forms, UIs) | Unstructured (emails, chats, documents) |
| Human interaction | Minimal | Conversational, contextual |
| Example | Invoice data entry | Customer service agent solving a case |
