whether it is possible to drive a stepper motor from speedy 3's output

[mdu]

actually i am trying to design an voice controlled wheel chair for my application wat i have did is tat i have writern two programs using labview one is just storing my voice for four commands(namely front ,frontright ,frontleft,stop) ,tat  it stores some value in an array, in my second vi i am speaking one of the four commands, and tat comands amplitude is stroed in an array and i am just comparing it with the values from the first array which i have stored it for all the four commands if any of the array value matches just approximately the i have to make the stepper motor to drive in tat direction i have done it with PIC microcontroller can u give some directions to implement using speedy33

Have you seen this?

no sir just now i saw tat ,i have completed almost 75% of the project what i have did so far is tat  i have just writern the two programs and i have done using serial port in labview and i have programmed the microcontroller also. wat i am trying to do now is to upgrade my project using NI SPEEDY33 while doing tat i got the doubt whether it possible to drive a stepper motor from speedy33's output

[mdu]

sir please give some guidance

Hi,

The SPEEDY-33 Robotics Daugher Module is an add-on device that mounts onto the SPEEDY-33 to provide more functionality. It includes:

• DC Motor Drive Outputs (4)
• Auxiliary Servo Motor Outputs (4)
• Analog Inputs (4)
• External Power Supply Connection

Details of the daughter module, you cn find at the link below:

This daughter module is NOT an NI product.

For connecting a stepper motor, since speedy 33 has digital outputs, it is possible to work a stepper motor. However, you will have to connect a stepper motor drive inorder to amplify the signals to the current specifications that the stepper motor demands. Find out the specs of your motor and choose an appropriate drive.
