So we looked for a sensor with a 0.1 mm accuracy as far as the agar height is quite thin (less than 1.5 cm). For that we though it would be good to use an ultrasound sensor because it can detects any time of material which a quite good accuracy. The part we're currently working on is to get the height of the gel that is in the petri dish because we need to tell the robot how deep he has to go or not to get the bacteria colony without destroying the gel and the all plate.

Here is a link of an open-source project that we used as a start for our project to get an idea of what we're working on : This first part is almost done as far as we can get a picture of a petri dish and return the data to our computer and then move the robot to each colony position. In order to do that, we use a camera to take a picture of the petri dish and detects all the bacteria colonies using ImageJ (a picture treatment software) and managing all this data (size, position, number of the colony) on Python. The goal of this project is to use a robot arm to collect bacteria colonies in an agar petri dish (it's a plastic plate with a sort of gel in it which feeds bacteria colonies). So first of all, what we are working on is an open-source project with a robot, the uArm Swift Pro(website link : ) which has an AtMega2560 in it but we also bought the controller (Here is the spec for the controller also powered with an AtMEga 2560: ). I'm sorry I did not linked any of the specifications before. At least your post is legible and has punctuation and properly spelled words. You've done far better than most of the American posters on the forum. Or at least a link to where you got it so we can maybe look for one if someone has the time.Īpologize for the english mistakes I may have done and for my poor knowledge in arduino.

What property would it measure?Īn actual link to the specifications of the sensor where we can see how the manufacturer says it is supposed to work would be a lot more helpful. I get that it is the height of the agar in a plate, but I don't really know what kind of sensor you are wanting to use here. I'm still not certain what you want to sense. That just reads the voltage on a pin if it is high or low. It certainly wouldn't be read with digitalRead.

Reading from that assumes that your connected device is transmitting serial data. Serial.begin does set up a serial connection on pins 0 and 1 at 38400 baud in your case. Yeah it sounds like you have no idea at all how this works. Same, you shouldn't assume we know what that is. You should probably not assume that many people here know what that is. I apologize for the english mistakes I may have done and for my poor knowledge in arduino. Just to know there are 2 outputs on the sensor, one giving like 64 0 then 64 1 bit and the other one is probably the one to get the distance which does not send any 1 if nothing is in front of the sensor and then gives a randomly 1 and 0 that does not seem the same at all (even if the sensor isn't moving). So we are wondering if we should get another sensor (an analog one) which would be easier to analyze as far as you just need to read an analog pin and then calculate the value with the specifications of the device or is there any way to get the data from the IO-Link one? I then just digitalRead the pin and I also tried waiting for a high bit and then putting the 15 next bit in a table and then print it but the result doesn't change whether I put my hand closer to the sensor or just let it watch the ground (it's usually 1111 + 12 zeros) but when there is nothing in its range it does not send any data (only 0 bits). begin(38400) makes the arduino getting data at this rate which is the same as the sensor). I'm reading the message at the same baud rate as the sensor specification (I suppose writing. So the fact is we're trying to get the data on a digital pin through an arduino Mega 2560 and we're supposed to get a 16 bit message with 1 bit for the state of the output and 15 for the measured distance.īut what we get is really messy, it does not look like a 16 bit message. We took a sensor which is a microsonic +25/F one (an industrial sensor) because we though this would be easier to get a data bus instead of having an analog sensor which could have been less accurate. I'm currently working on a colony picker project and for that we need to get the height of the agar gel so that our robot arm knows where the surface of the agar is.
