This is a simple pinless active attachment for the SUV Box Robot.
In this attachment we use "(32498) Technic Gear 36 Tooth Double Bevel". There are four pins added to the wheel and it it this pins that engage with the "(32072 ) Technic Gear 4 Knob". The more important thing is that the knob wheel and the gear wheel are parallel to each other.
While the motor rotates the attachment has 4 points of contact (instead of one or two when two Knob Wheels are in contact) with the robot knob wheel. There are no forces that drive the attachment to jump and lose engagement with the robot.
