Hi. My school’s other team has used all of our distance sensors, but we want to detect when our claw could close on a mobile goal. Could we use a optical sensor for this? I saw that you could use “isNearObject”, but I do not know how to set how close it is. Thank you!
Basically no, the optical sensor is not equipped to sense distance. I’d recommend a bumper switch instead.
Ok. Otherwise, would a rangefinder work?
Sensors are great for the interviewing so I would rather use some of them.
It can detect when something is close, I forget the threshold, but 2 or 3 inches perhaps.
/** * @brief Check to see if an object is detected by the optical sensor. * @return Returns a boolean that represents whether an object has been detected. */ bool isNearObject();
A bumper switch is a sensor. In an interview you could say having a button that makes your claw close is much more consistent than a distance sensor.
Ok. Thank you 20 char
Ok. Thank you! My question was the threshold.
do some experiments, it can be changed with this function.
/** * @brief sets the value of the detection threshold * @param value The new detection threshold in proximity units (1 to 255). 0 means no change. * @return the current value of the proximity threshold */ int32_t objectDetectThreshold( int32_t value = 0 );
but there are no units attached to that and it will change depending on how reflective the object being detected is.
