Why do we need to hold down the freedrive button for UR?

ZH2112

Is it some kind of safety configuration? I just find it much easier to move the UR with both hands :<. Sorry for stupid question LOL XD

@ZH2112, it would be possible to install a switch on the IOs and assign it to the freedrive function. This would allow you to turn on the freedrive and move the robot with two hands. You can assign the IO function from the installation tab.

@newuser, this has been available for as long as I can remember.

1. Wire your switch into the controller 24V and DI0, for example.
2. Go to the installation menu of the Polyscope, and then under IO Setup.
3. Assign the DI0 the Freedrive action:

4. Once the switch is turned on, you should be good to go.

What version of the UR will this work on? Can someone please provide a guide on how to do this?

Would there be any significant downside to having freedrive on all the time? I've also realised I could have just connected 24v to a desired input and assign freedrive when needed.

@ZH2112, you won't be able to run any program while on freedrive if I'm not mistaken. It can be activated from within a running program using some specific functions though.

You also might want to jog the robot to a specific or more precise position at some point, this would be impossible with the freedrive on.

@ZH2112 I agree, it's easier to move the robot with both hands. This is why in Alumotion we made the YOUring: a tool to mount on the wrist3 of the UR; it allows you to move the robot with both hands, by pushing a button directly. On our website: tools.alumotion.eu/youring you can find documentation and videos!

Hello @Nicholas_Francoeur @newuser

I'm really interested by this !

I have a UR3 and I want to add the freedrive mode for a short time in the program.

Is there a guide that shows how to activate the freedrive mode into a program ?

Thank you !
