Main Contractor: Dutch Space (Leiden, The Netherlands), leading a consortium of many
subcontractors

4. Robot Arm The European Robot Arm
Large symmetrical robotic arm with 7 degrees of freedom
The arm consists of 2 End Effectors, 2 Wrists, 2 Limbs and 1 Elbow joint together with electronics and cameras. Both ends act as either a “hand” for the robot or the base from which it can operate.

5. Robots are used in a variety of roles
Robots are used in a variety of roles. They are now designed to perform repetitive simple tasks.

6. Dexterity Vs. Power
Some robots are used when human strength is not enough
Some robots can have as much dexterity as a human hand

7. Robot Arm We will build a robot arm from simple materials
The arm must pick up a plastic cup containing a set of keys from a distance of 45cm
Lift the cup to a height of at least 15cm
Pour the keys into another cup without dropping the original cup or knocking over the new cup
Bring the cup back to rest and release it

8. You cannot get any closer than 45cm to the cup at any time
