Are Ultrasonic, Touch, and Color Sensors Considered Tactile Sensors?

[Muhammad Saboor]

Are ultrasonic , touch, colour sensors type of tactile sensor? I have been told not to use tactile sensor in my project. Can anyone name few sensors that are tactile and others which are non-tactile?

PIR, light sensors, acoustical ie ultrasonic aren't tactile.

Here's a description of tactile sensors:

https://en.wikipedia.org/wiki/Tactile_sensor

and with more detail:

and a nice slide show:

but slide shows ultrasonic is tactile sensor.

It depends on the sensor use. THere are ultrasonic sensors that measure distance to an object and there are others that are used in touch applications.

The pdf shows an ultrasonic tactile sensor:

and this reference shows one used in simple robotics projects (2nd page in pdf):
