Just picked up five mBots for school ! Yeah!

#1

I picked up one before Christmas to test and I found it to be easy to use, once I figured it out ; ).
Firmwire update!!!

So now I have gone forward and picked up five mBots (bluetooth) to use at school. I chose the bluetooth over serial for ease of use. Pairing to iPads will be easier over bluetooth.

I’ve got a few questions: Is there a full rotation servo motor that would fit into the mBot? I might have to drill, but it would allow programming movement.
I want students to be able to program the bot to move forward for 1 sec. (or better, rotations) turn left .5 seconds (or 20 degrees ! ) etc.

Thank you!!

The motors can be controlled by using the sequence:

[run forward] at [speed]
wait [secs]
[run forward] at [0]

It’s really a good exercise to have the students calculate the circumference of the wheels, then take measurements for the distance traveled to back into the rotations. From that point, it’s relatively easy to make a custom block that works on rotations (or distance to be traveled). :slightly_smiling:

The same would hold true for determining the factors for turns. :slightly_smiling:

I think that can be done with a stepper motor
