Collision without forces

[pea]

Hello,

I would like to build an excavator and be able to pick up some objects (e.g. boxes) with the bucket . Therefore, the bucket (I built collision objects in form of boxes around it that stick to the bucket) shall collide with the objects.
When I activate physics and forces my collision objects either fall on the ground or - if I deactivate gravity - they fly slightly away.
I just want to activate collisions for the bucket but no forces, is this somehow supported?

Best,
Pea
