Selecting a Robot Controller

The following 10 questions can help when selecting a robot controller, according to Joe Campbell, Adept Technology’s VP:

1. Is the application path intensive or pick and place?

Software optimized for path functions will not deliver the performance required for high-speed applications.

2. How fast is the required I/O response?

While most I/O devices respond happily in milliseconds, some functions like stop-on-force or motion latching require microsecond response.

3. Where is the sensor?

If the sensor is external to the controller, assure enough processing and communication bandwidth.

4. Are you safe?

Assure compliance with safety standards including ANSI 15.06.

5. Going international?

If so, make sure controller (or systems) has the CE mark.

6. Is your "open" architecture closed?

If you plan to add third-party boards or software, make sure the vendor allows it.

7. Do you know your networks?

Make sure you know exactly what hardware connections and software protocols are available.

8. Need dual robots?

If using two robots in a single cell, determine if you can live with one controller or if two will be necessary.

9. Do you have enough software power?

Match software power to the application.

10. It's just another controller, isn't it?

Apply traditional control engineering guidelines in determining I/O capacity; selecting and designing the graphical user interface:, and providing power isolation and backup, enclosures, and other interconnects.
