Hi, thank you to all for your answers,

battery pack is new, I buyed it on march 2016 here: http://www.conrad.ch/ce/fr/product/206028/Batterie-daccumulateurs-NiMh-Conrad-energy-72-V-3000-mAh-fiche-Tamiya-male/SHOP_AREA_20058

I does not use I2C, just the camera, some servos (4-6V but max range 9V), and 2 leds with pwm, and 2 digital inputs with pull-ups to detect collisions.

I uploaded my robot project to the community, so if you want to see if there is something wrong I will thank you, but it is the first time in one year I have this problem. Sometimes when I use keyboard arrows, it turns just left even if I push forward, right or reverse.

Thank you

Luis

I think that if ARC crashes first, it has to do with your PC (software). Can u test it in another computer?

The EZ-Script manual defines how to use IF/ELSE/ENDIF statements. The syntax you are using will cause runtime errors. For example, in the CHECKBOX LIGHT of the mobile interface.

You have:

if ($Checkbox == 1) {
  PWM(d4, 50)
}
endif

if ($Checkbox == 0) {
  PWM(d4, 0)
}
endif

It should be...

if ($Checkbox == 1) 
  PWM(d4, 50)
endif

if ($Checkbox == 0) 
  PWM(d4, 0)
endif

Or more effeciently it should be...

if ($Checkbox == 1) 
  PWM(d4, 50)
elseif ($Checkbox == 0) 
  PWM(d4, 0)
endif

The EZ-Script manual also states that a servo position must be set before initializing the speed. In your Script Init Servos, you have...

ServoSpeed(D0,2)
ServoSpeed(D1,2)
ServoSpeed(D12, 1)
Servo(D12, 90)
#ControlCommand( "Script", PareChocs() ) 

It should be

Servo(D0, 90)
Servo(D1, 90)
Servo(D12, 90)
ServoSpeed(D0,2)
ServoSpeed(D1,2)
ServoSpeed(D12, 1)
#ControlCommand( "Script", PareChocs() ) 

Those two should not cause the lockup of ARC. However, there are quite a few reads in PareChocs. I believe it would be incredibly beneficial for you to upgrade to a EZ-B v4/2 Comm Upgrade. It's much faster with reads and will benefit your custom robot. I see you wish to explore navigation and high speed PING reads, the EZ-B v4/2 Comm Upgrade will perfect for that scenario.

Thank you DJ Sures,

I was sure that the glitch were in my brain , so when I go home, I will try it and for sure I will buy EZ-B v4/2 Comm Upgrade and may be someother parts, if all goes well. it's a great idea the possibility to change port server so I will control it through internet without open port less than 1023.

OK, thank you,

my servos are now working well, and when I wrote code for lights it was incorrect, I was coding in C confused and the <servo(dx, 90)> solved that in servos init for the movements.

Now, I just have connections problems, when the wifi connection is lost, the software hangs, but I can unlock it by forcing Windows to kill the task, and then I cancel, then the software is responding again.

I will buy a new wifi router connected to my internet modem, a wifi just for my internet things connected (Karotz, Mother, Ez-robot, and soon Mebo and Chip the dog)

When all will work with my ez-robot, I will put it into that toy (if I can):

I will tell you if my new wifi router will solve my ez-robot disconections

Thank you to all Luis

Hey Luis, are you running antivirus software? If so try turning it off. This is the #1 problem with connection issues.

If you haven't already read the WiFi connection trouble shooter tutorial. There are a lot of things you should check first before buying a new router.

Second and third biggest issue is a weak WIFI signal or a crowded channel. However when I first got my first V4 I ended up having to get a new router along with a remote access point (Engenius eap600 access point) to solve my problems. I had a very old and outdated router and my robot is in the basement with the router on the 1st floor. Doing this actually not only solved my EZB connection problems but also enhanced my entire home network.

Before you spend too much money on routers and anything else, I recommend the /2 upgrade first.

Also, as Dave mentioned disable anti virus because it has trouble understanding the complex byte level protocol for ezrobot - also the ports.

Hi all,

Thank you DS Sures, the problem was in my code, I rewrote it with your examples, then I deleted the U.S. radar (waiting for EZB v4/2) and all movement are working well.

I had some wifi disconnections but I have now a different wifi network with a router different that my family uses (we have a lot of internet consumers like tablets, phones...).

I was reading a topic that says if the wifi network channel is too populate it can cause wifi issues.

I can not wait for my EZB v4/2 I orderded with some other parts. Winter is comming and it's time to make robots !

Thank you to all answered me
