Teensy PCB Ardumower (T-Mow)

[Sascha]

I used a Matrix MOW800 with this Driving Motors.
If you are looking for cheap motors and battery look at Ebay for it. I have buy 2 off them.
With luck, the battery is there and intact. They also have a charging station for a little €. If I remember correctly, charging station + charger 60 €
But I'm working on the integration of the motors into the software. They don't really want it yet. But they work already.
You need 3 off this Motor Driver for it.

OK, thanks Sascha for infos. I will watch this.

 

[Bernard]

@Sascha Be carreful with BL motor and the odometry it need to work perfectly with at least 300 ticks / rev or you need to write a new soft

 

[Sascha]

@Bernard
Yes I know that. I am already glad that the Motors do move
Odometry comes next, I have to search in your code how to integrate it into the test code, that i can see the Ticks.

 

[LaurentS]

Sascha, your fault.... I just ordered 2x Matrix MOW800... but they are for sale without charging station. I think I will have enough things to do with thoseones, just to learn how to adapt PCBs etc... without thinking on printing strong PETG parts. My 3D printer will be used for smaller parts.
Thanks for your help !

This part of code is easy it's simple interrupt management.

  attachInterrupt(digitalPinToInterrupt(pinOdometryRight), OdoRightCountInt, RISING);
  attachInterrupt(digitalPinToInterrupt(pinOdometryLeft), OdoLeftCountInt, RISING);

and

void Robot::OdoLeftCountInt() {
  Pulse01 = micros() - Pulse02;
  if (Pulse01 > 10  ) { // debounce for 120uS
    Pulse02 = micros();
    if (robot.motorLeftPWMCurr > 0 ) robot.odometryLeft++; else robot.odometryLeft--;
  }
  asm("dsb");

}

You have test on my git inside test file under interrupt test pin12

MOW800 --> There are really for sale at this price ?

Oh no what have you done?
Now I am forced to integrate the Brushless Code into the Software.
I have asked them on Ebay, if they have Stations for the Mower.

@Bernard yes really. but sold as defective, it may be that something is broken

 

[LaurentS]

I paid 69.90€ plus resend to France via ColisExpat.

 

[Sascha]

Ah ok now without Akku:

"As a spare part / defective without battery, accessories and charging station at most software problem"

The software problem is the intern who wrote the software and probably never tested.

I just sent a mail to the seller, maybe they have for sale... .

 

[LaurentS]

Time to go to work; see you later Sascha and Bernard.

 

[Sascha]

I'm trying to get Odometry running and was wondering why I don't see anything on Odometry Left, only the left motor is connected.
I noticed that the labeling of ODO_Left and ODO_Right is reversed.

Please remember when you connect the motors!

 

[LaurentS]

Hi Sascha, the seller has charging stations for sale, ...also for 69.90€. Is it a good deal or is it possible to build one who will do the job as good as the original, is it worth it ?

 

[Sascha]

I can not complain, it is just a normal charging station with two charging contacts and the connection for the charger and two LED's.
The electronics have to come out anyway and the loop transmitter from Bernhard has to go in.
But there is no complete circuit board yet.
Is it charging station and charger for 69€? I do not know it at all more.

Here a picture:

 

[LaurentS]

He wrote Ladegeräte, not Ladestation... I resent him a mail to be sure what he's speaking about. Thanks for this nice picture.

 

[LaurentS]

Just received... waiting on electronic components.

 

[LaurentS]

@Sascha are your R12-R5 Resistors correctly soldered ? Bernard changed R12 position, because in your case, 1/J1 is connected between R12 and R5 instead of on the right side of R5 ?

 

[Sascha]

Yes, on the picture from Bernard, is the previous version of the PCB, there was a small error in it, the resistors were set incorrectly

I don't understand, for me the pcb is not like what can be find on schematics. 1/J1 is connected between R12 and R5 and not on the R5 right side.
