I want to add a LOT of sensors to the mBot

#1

I wish to add more sensors to the mBot that there are ports on the mCore board…9 sensors total.

I see the Me UNO Shield, but it doesn’t look like it is meant for the mCore.

Is there a simple way to do this?

I don’t think you can add it to the mBot. But you can try to pick out the sensors you most want and put them on. Hope I helped! :slight_smile:

What do you want to add? Some sensors are already on board. Microswitches could share a port.

#4

My Suggestions are Add Line follower, A led, and then what you want.

#5

I want to add at least 3 more Ultrasonic sensors and 4 more IR sensors.

I’m going to design an expansion board to allow for this if there isn’t a ready-made option.

#6

Not sure what you want to build. But you might consider to use servos to move single sensors in different directions instea of using multiple sensors. Maybe that is a solution for your use case.

We are using the mBot as a base for testing machine learning using neural networks.

We want the robot to be able to roam around a bit, but have found that one sensor in the front doesn’t cut it. We considered the rotating sensor concept, but that adds a lot of complexity for the robot to learn…that part would probably require a lot of ingrained coding.

We plan to put an ultrasonic sensor on all four sides and likewise use IR sensors all around. These are simple enough for the neural network to assimilate. With a rotating sensor, the network would have to understand that the data from the one sensor could be from any direction…not as simple for it to learn.

Of course, creating the expansion board will be complicated, but just as evolution has given our brains a sophisticated eyeball with built-in processing, we will give our little mBot toddler a little help on the sensor front.
