Robotics (ME-604 (A)) - Important Questions

  1. Unit 57 Marks High Priority

    Explain work‑cycle time analysis for an industrial robot. Define the components of cycle time and discuss the factors that affect total cycle time in a pick‑and‑place operation.

    Core topic on robot cycle analysis; appears frequently in unit 5 analytics (work‑cycle time analysis). Typical 7 mark short answer or 14 mark with numerical derivation.

  2. Unit 514 Marks High Priority

    A robot performs a repetitive operation consisting of: approach, grasp, transport, place, return and tool change. Describe a systematic method to compute the total cycle time given individual operation durations. Explain how variable delays, acceleration/deceleration limits and path planning influence the computed cycle time and production rate.

    Application / numerical problem derived from the work‑cycle time topic; commonly set as longer problem to test calculations and interpretation.

  3. Unit 57 Marks High Priority

    Discuss the economics and effectiveness of industrial robots. Explain the methods used to evaluate economic feasibility such as payback period, return on investment (ROI), net present value (NPV) and factors that influence robotic investment decisions.

    Core economics topic; frequently asked in unit 5 under 'Economics and effectiveness of robots'.

  4. Unit 57 Marks High Priority

    Describe the safety systems and devices used in industrial robotic installations. Explain the working and application of guard interlocks, emergency stop systems, light curtains, pressure sensitive mats and safety PLCs.

    High‑priority safety systems topic; often required as descriptive answer in exams.

  5. Unit 510 Marks High Priority

    Prepare a safety layout and risk assessment procedure for a single‑robot machining cell handling raw parts and tools. Describe the steps to identify hazards, estimate risk, select protective measures and verify compliance with relevant standards.

    Applied safety design question; tests ability to perform risk assessment and design a compliant safety layout for a robotic cell.

  6. Unit 57 Marks High Priority

    Explain the testing methods and acceptance rules for industrial robots. What tests are performed during acceptance trials (accuracy, repeatability, payload, dynamic performance) and what acceptance criteria are typically used?

    Testing and acceptance rules topic; appears repeatedly in unit 5 analytics and is a standard RGPV question area.

  7. Unit 57 Marks Low Priority

    Define accuracy, resolution and repeatability of a robot. How are these measured and why are they important?

    Fundamental measurement definitions frequently requested by examiners; included in global important questions list (preserved verbatim).

  8. Unit 57 Marks Low Priority

    Discuss various sensors used in robotics (encoders, proximity, tactile, vision). How do you select a sensor for a given task?

    Sensor selection and description is a common conceptual question for robot unit; preserved from global top questions list.

  9. Unit 57 Marks Low Priority

    Compare teach‑pendant programming, walk‑through/manual programming and offline programming for industrial robots. Give advantages and limitations of each method.

    Programming methods comparison is a standard conceptual question; preserved from global top questions list and relevant to unit 5 practice and implementation issues.
