My Robot Designs: Amphibian & Underwater Robot

jeffrey samuel

Nice to have you with us friend

Welcome to CE

Can you please share some of your robotic designs here in the forums

thank you.
i havnt got formal designs. just some hobby works. which i have posted earlier. i havnt documented most of my works. will share my future works if possible.

If you could offer some description, I'd move this thread as a separate showcase thread in our robotics / rc section 😀

the first picture is of an amphibian type which can be used both in and out of water. the other pictures are of an underwater type which can swim below and on the surface of water

,sir, good day, i'm just wondering, what does your robot do?? i'm looking for project ideas for my final year and i think this one of yours is cool.

I think this robot same as submarine robot, i read about it on the internet, it is cool idea for a mechatronics project. you can read about it and how to design low cost one by searching about it using google.

,thank you so much, that's definitely a great help maam, 😀)

Hey friend Why not specifying where you are having difficulty in designing the BOT we can help

Instead of asking a person for design aids to remove your problems you can post the place where you got stuck while designing

I make a simple color sorter machine which includes 4 stations one for metallic object, the others for red, blue and green objects. the system has dc-motor to drive the conveyer belt, inductive proximity sensor to detect metal object, color sensor to detect the object color, pneumatic actuators to deliver the object to its station and a plc, the problem is i cant find how the color sensor will tell the plc what is the color to make the proper pneumatic actuators to activated. by the way it just case study project not a practical one.

In that case, what is the type of your color sensor? Is it analog or digital? In either case, the sensor should give you 3 values for intensity of RGB. Now one method I could think of now is to prepare a small look up table with different labels corresponding to the rgb value ranges. Obviously you wouldnt require to distinguish between, for eg., light red and light red. This approach will fail if you do require things to be like that. But other than that, you can easily catagorize broad colors very easily.

since i use a plc its required to be an digital input, unless the plc has A/D converter it will be analog signal. maybe colorSENSOR LT-3-LU will work.

PLC requires a digital signal doesn't necessarily means that the sensor MUST digital one. In fact, most sensors will be analog & are you with ADC for processing their data. As you didn't mentioned the actual specification/model of your sensor, I've asked you for that information.

So now you've a color sensor now. What's the exact problem you're facing? Now if that sensor is available to you, you readily have your color detection.

what color sensor you used ?
