I recently started to work with the 6 Axis Arm.
It seems that whenever i try to control the shoulder servo (the top most servo that would lift the entire arm) as soon as i try to move that servo, it stops and i lose the bluetooth connection.
Why does this keep happening?
I made my own C# project for this and the following is how i am controlling the shoulder servo:
m_ezbConn.EZB.Servo.SetServoPosition(Servo.ServoPortEnum.D13, valueOfTrackBar);
Is this not the correct command for that shoulder servo?
This is how i command the other servos on the arm and it works just fine.
Any help would be greatly appreciated
This sounds like that servo is drawing more current than the board can handle and you are getting a "brown out". This has happened to many people on the forum. You may need to power this servo separately from the EZ-B. I had to do it with mine because of the same scenario and it works great now.
Bret is correct, it is a brownout - you can use a stronger battery also. The 6 AA battery pack sent with the EZ-Robot Complete Kit is designed for light and small robots. We included the dynamic power adapter so you can connect different battery sources to the EZ-B. Batteries that most of us use are Sealed Lead Acid and can be found at most electronic shops. They're the type of battery that is found in Alarm Systems and Emergency Backup Lights. They are usually 6-12 volts, and 3-6 amps. The more amperage, the better of course
The servos were drawing too much power from the board, that was exactly the issue.
Now I put all the arm servos onto their own power supply and it is working perfectly!
Thanks for the help guys
Can someone please recommend a good website to purchase Sealed Lead Acid batteries?
How did you connect only the arm servos into a different power supply?
I am able to run this off an eight cell pack for a long period of time with no issues.
