This attachment uses a connector ("(98585) Technic Connector Circular With 2 Pin Holes and 3 Axle Holes") with 4 pins to connect with a knob wheel ("(32072 ) Technic Gear 4 Knob") of the robot. Because both elements are parallel one to another there is no jumping effect.
The attachment uses two pins, but it is easy to attach and detach because it uses "(6558) Technic Pin Long with Friction and Slot". When you attach or detach the attachment the slots are keeping the pins strong on to the attachment.
Also an attachment connected to the robot in this way, can be move to the rigth knob wheel or to the left knob wheel.
