Rotary motion to lift a dump truck

[Leo t]

Homework Statement

In my robotics class I was task with creating a robot to lift and house objects, I have the lifting mechanism, and a housing area, but I can't figure how to get the bucket of the robot to dump using a rotary motor.

Homework Equations

The Attempt at a Solution

Tried to fixate a gear at the back have to leverage up, but it doesn't pivot, it just drags the bucket off, any ideas.

No, I'm not allowed phones in school. I only have access to rotary motors, and I'm trying to make a working dumper on a robot, like a dump truck

Maybe attach a string to the bottom edge of the bucket and have your motor spin to wind up the string...?
