Ezrobot Restart Itself When I Use The Servo

Est-ce que je peux avoir de l'aide en Français ?
J'ai un problème lorsque j'utilise un servo, le boitier EZ-B redémarre tout seul.

Voici le message d'erreur :
Comm Err: System.IO.IOException: Impossible d'écrire les données sur la connexion de transport : Une connexion existante a dû être fermée par l’hôte distant. ---> System.Net.Sockets.SocketException: Une connexion existante a dû être fermée par l’hôte distant
à System.Net.Sockets.Socket.Send(Byte[] buffer, Int32 offset, Int32 size, SocketFlags socketFlags)
à System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size)
--- Fin de la trace de la pile d'exception interne ---
à System.Net.Sockets.NetworkStream.Write(Byte[] buffer, Int32 offset, Int32 size)
à EZ_B.EZB.M3jweGrVXK(Int32 , Byte[] cmdData)
BbytesToExpect: 0

Je comprends que ça vient de la connexion réseau mais je sais pas comment résoudre ça.

I have : EZ-B v4/2 Wi-Fi Robot Controller
EZ-Builder Version 2017.01.29.00

"Sorry, but, I'm so French, so I speak very bad English. But I love EZ-Robot too, so I'm going to get serious about English.":)


Upgrade to ARC Pro

Synthiam ARC Pro is a cool new tool that will help unleash your creativity with programming robots in just seconds!

You need more power... Your batteries are probably no good or the wrong type... This battery will work well... 7.4V Lipo

Sorry this is in English...
Powering your EZB4
Thank you for your answer, it is in English but I understood !
I use an electric transformer that produces 9v 700mA
Can be a lightweight at 700mA ?
I will test your hypothesis by changing battery.

Merci, heu, thank you....
@FDW34 You need 5000mA (5A) minimum.... Best for many servos is a 20A power supply ... 700mA is not enough....
I use a Meanwell 6V 50A power supply for my inMoov robot...
Utilize un lipo batterie de plus intensité de courant , ou utilize un source de courant plus de 10A.

(Je suis etudie francais, et comprendre il un peu.)

More power! Use a higher capacity lipo battery if possible, or a high amperage power supply at least 10 amps in delivery. More servos means more power.
I recommend...

- LiPo Robot Battery 7.4v 1300mAh
- LiPo Battery Harness
- LiPo Battery Balancer Charger

Thank you for your answer.
With this battery, how many servos can be used? And what is the average autonomy?
JD runs, I think 17 servos on one of those batteries. Six runs 12.

I think your "average autonomy" question may have been a translation error. If you mean how long does the battery last, it varies on how much moving you are doing, but I would say an average of 10-15 minutes.

I tested with another battery and it works. Thank you for your answers.
