One of my favorite instruments for robotic surgery is the PK dissector.
As all daVinci instruments, It is made by intuitive surgical. It was developed in combination with gyrus medical.
It is a bipolar instrument that can be used instead of the maryland bipolar or precise bipolar.
The main advantages include:
Less charring and sticking to tissue.
A wider opening angle to grab tissue easier.
Sound feedback to tell you when the tissue should be coagulated enough.
The main disadvantage is the blunt tip which makes it less useful as a dissector than the maryland bipolar (but more useful than the blunter precise).
For surgeons interested in obtaining this you also need a gyrus PK generator to provide the input.
