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. http://www.esa.int/esaHS/ESAQEI0VMOC_iss_0.html

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.

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

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

You cannot get any closer than 45cm to the cup at any time Robot Arm You cannot get too close… Robot Arm Student Cup 45cm You cannot get any closer than 45cm to the cup at any time
