How can I make a jerky hand movements

Hello,
I am a beginner in unity. I am building a project and I could not figure out how can I make a jerky hand movements of a humanoid robot (Banana man).

I tried rigging the banana man but the movement is smooth.

Scenario:
I will give the target position to the banana man and it should move the hand to that position but the movement should not be smooth.

Thanks for the help!

Are you animating in Unity or another application?

I can see in the manual there’s instructions on how to edit animation tangents: Unity - Manual: Edit Animation curves

In a other application you’ll have to read up one how to this. It’s usually referred to as ‘stepped animation curves’.

I am using Unity. Thank you for providing this link, it helped a lot.
