- Payload
- The maximum weight at the end of the arm: part + gripper. Always leave about 20% margin.
- Reach
- The farthest point the arm reaches from the centre of the base. A 1.5 m tall pallet usually needs at least 1600–1800 mm.
- Cobot
- A collaborative robot. It stops on contact with a person, can work without a fence and is taught by guiding it by hand.
- Industrial robot
- Faster and stronger; works behind a fence or with light barriers.
- IP rating
- The first digit is dust protection, the second water. IP54 for an ordinary workshop, IP67 for washdown and the food industry.
- Repeatability
- How precisely the robot returns to the same point. ±0.03 mm is more than enough for most tasks.
- Axes (DOF)
- The number of joints. 6 axes give full freedom of movement; 5 axes are enough for palletizing.
- Gripper
- The robot's "hand" — with fingers, vacuum or a magnet. The choice depends on the part.
