Gripper
A gripper is the "hand" of a robot that allows it to pick up, hold, and manipulate objects. Just like human hands can grasp different items, grippers are tools attached to robots that help them interact with objects in their environment. They come in many forms - some look like human fingers, others like suction cups, and some are specially designed for specific items. When someone mentions experience with grippers in their resume, they usually have worked with designing, programming, or maintaining these robotic hands in manufacturing, warehouse, or research settings.

Example Interview Questions
Senior Level Questions
Q: How would you approach designing a gripper system for a new product line with varying object sizes?
Expected Answer: A senior candidate should discuss analyzing product requirements, considering different gripper types (mechanical, vacuum, etc.), testing procedures, and how to make the system flexible enough to handle multiple products.
Q: Tell me about a time you solved a complex gripper-related problem in production.
Expected Answer: Look for examples of troubleshooting experience, problem-solving skills, and understanding of how gripper issues impact overall production efficiency.
Mid Level Questions
Q: What factors do you consider when selecting a gripper for a specific application?
Expected Answer: Candidate should mention object weight, shape, material, speed requirements, environmental conditions, and cost considerations.
Q: How do you ensure safe operation of robotic grippers in a collaborative environment?
Expected Answer: Should discuss safety protocols, force limitation, collision detection, and awareness of safety standards for robots working near humans.
Junior Level Questions
Q: What are the main types of grippers used in robotics?
Expected Answer: Should be able to describe basic types like mechanical fingers, vacuum suction cups, and magnetic grippers, along with simple examples of their uses.
Q: How do you program a basic pick-and-place operation using a gripper?
Expected Answer: Should demonstrate understanding of basic movement commands, grip force control, and simple positioning operations.
