Line 32:

* Complex Vision: Recognition of shapes.

For motion control, potentiometers, tacho-generators, encoder, etc. are used as joint sensors, whereas strain-gauge based sensing etc., are used at the end-effector ___location for contact force control.

==Internal sensor==

Internal sensors as the name suggests are used to measure the internal state of a robot , i.e. its position, velocity, acceleration, etc. at particular instant.

'''Position sensors''' measure the position of each joint i.e., the joint angle of a robot. Different position sensors are explained next.

* Encoder: Encoder is a digital optical device that converts motion into a sequence of digital pulses.

* Potentiometer:Potentiometer, also referred to as simply ‘pot’，is a variable resistance device that expresses linear or angular displacements in terms of voltage.

Line 44:

'''Velocity Sensors''' or speed sensors measure try taking consecutive position measurements at known time intervals and computing the time rate of change of the position values or directly finding it based on different principles.
