Questions & Answers

Q: Why are general purpose robots not perfect at any one thing?

General purpose robots are designed to handle a wide range of tasks, making it challenging for them to specialize in one area. They prioritize versatility over specific skills.

Q: Why do robots need to deal with uncertainty?

To be useful in the future, robots should be able to handle unexpected situations and adapt to unpredictable environments. Dealing with uncertainty enables their successful operation.

Q: What are some common failures of general purpose robots?

General purpose robots can struggle with simple actions that humans take for granted, such as grasping objects accurately or maintaining balance in response to external forces.

Q: How does predictive control contribute to robot performance?

Model predictive control allows robots to predict and adapt to future scenarios. By constantly updating their predictions based on real-world feedback, robots can optimize their actions and respond effectively.

Summary & Key Takeaways

• General purpose robots aim to be versatile but struggle to excel in specific tasks due to the need to handle uncertainty.

• Robots often face unexpected situations and fail to anticipate certain actions, such as missing a door handle and losing balance.

• The development of general purpose robots requires predicting and adapting to different circumstances, similar to how humans adjust their actions when handling objects.
