Light can be transmitted

Reflect,

We have developed an optical proximity sensor for robots.

Parts such as glass and plastic can be gripped smoothly.

Optical proximity sensor for robots:

Equipped with a light emitting diode (LED) and a light receiving element at the fingertips.

The reflection signal is measured to estimate the orientation of the surface to be gripped.

Pouch packaging that reflects light,

Transparent test tubes, etc.

The robot becomes easier to handle.

Eight LEDs are arranged:

Equipped with a proximity sensor at the fingertips of the robot,

Eight LEDs surrounding the light receiving element are arranged,

When the LED is illuminated, the light reflected by the gripping object reaches the light receiving element.

The reflected light intensity changes according to the angle of the surface, and the orientation of the surface can be estimated.

Operate clear glass and mirrors:

It works even if noise such as strong light is given during measurement.

There is no problem even if the sample is poured into the reagent bottle or the liquid level moves.

Conventionally, it has been difficult to handle transparent glass and mirrors with an optical sensor.
