I'm looking for simple sensors to make a robotic arm detect an object and then grasp it.
I don't find adequate sensors, capable of detecting and measuring the distance of small objects.
I found that sonars and I.R. sensors have large sensing beams, and can't precisely detect small objects .
Can somebody suggest adequate sensors for the purpose ? (other than a video camera).
I found a device with multiple IR sensors, named apds9960 , by Sparkfun, with I2C interface, capable of measuring short distances (10 -25 cm), and even capable of detecting movement direction .
Mounted near the grasping hand, it could scan the object and give information to drive the arm servos as needed.
Does someone know it or has some experience using it ?
