An offline programming workflow typically uses which resources?

• A. Manual teaching steps on the shop floor
• B. CAD models and simulation
• C. Live operator joystick input
• D. Only prewritten robot language code

Answer: (B)

Offline programming relies on digital representations of the robot, tools, and the surrounding workcell to create and verify robot motions before any real movement. CAD models provide the exact geometry of parts, fixtures, and end-effectors, so the robot can interact with them accurately in a virtual space. Simulation then brings everything together by animating the robot, checking reachability and joint limits, detecting collisions with parts or tooling, and estimating cycle times. This allows you to test and optimize paths, speeds, and sequencing without risking damage or downtime on the actual line.

Other methods don’t offer this virtual validation. Teaching steps on the shop floor involves programming while the robot is in use, which is online rather than offline. Live operator joystick input is real-time manual control, not a virtual development environment. Relying only on prewritten robot language code lacks the modeled geometry and dynamic verification that CAD models and simulation provide.
