NAO Anatomy: Sensing and Movement on Your Robot

The NAO robot has 25 joints and 25 degrees of freedom, or directions in which motion can occur on its body.  (For comparison, the human body has 230 joints and 244 degrees of freedom, wow!)

Here are all the joints and the ways they make the robot move:

HeadYaw

Moves the head side to side

HeadPitch

Moves the head up and down

ShoulderPitch

Moves the shoulder up and down

ShoulderRoll

Moves the shoulder in and out

ElbowYaw

Elbow rotation

ElbowRoll

Moves the elbow in and out

WristYaw

Wrist rotation

Hand

Opens and closes the hands

HipRoll

Moves the hip side to side

HipPitch

Moves the hip forward and back

KneePitch

Moves the knee forward and back

AnklePitch

Moves the ankle forward and back

AnkleRoll

Moves the ankle side to side

 

All the joints listed have sensors that keep track of them:

1. Position (So you can program movement)

2. Temperature (To alert you if the robot overheats)

3. Electric Current 

4. Stiffness of the joint

5. Position of the Actuator (That moves the limb) 

All these sensors can be used to program your robot.

But the joint sensors are just the beginning!  NAO also has two HD cameras, four microphones, and 10 tactile sensors (three on the head, one on the chest, one on each hand, and two on each foot).

NAO can be programmed to respond to movement, speech, facial recognition, touch, sound, and any combination you can think of!
