The main appeal of the spider's body in necrobotics is its compact leg mechanism and use of hydraulic pressure.<ref name=":2">{{Citation |title=Spider anatomy |date=2023-07-20 |url=https://en.wikipedia.org/w/index.php?title=Spider_anatomy&oldid=1166225476 |work=Wikipedia |access-date=2023-10-19 |language=en}}</ref><ref name=":4">{{Cite web |title=Leg Uses Hydraulics and Muscle Flex — Biological Strategy — AskNature |url=https://asknature.org/strategy/leg-uses-hydraulics-and-muscle-flex/ |access-date=2023-11-04 |website=asknature.org |language=en-US}}</ref> The spider's anatomy utilizes a simple [[Hydraulics|hydraulic]] (fluid) pressure system.

In July 2022, researchers in the Preston Innovation Lab at Rice University published a paper detailing their experiments with the gripper. Although dead spiders no longer produce hemolymph, Te Faye Yap (lead author and mechanical engineering graduate) found that pumping air through a needle into the spider's [[Spider anatomy|cephalothorax]] accomplishes the same results as hemolymph.<ref name=":0" /> The original hydraulic (fluid) system is essentially converted into a pneumatic (air) system.

The main limitations to necrobotics are its durability, maintenance, and questionable morals. With the usage of organic material, there is a higher chance of the component decomposing and breaking down as opposed to traditional mechanical systems. There may be additional work and management required to replace these grippers if they fail. Additionally, organic inconsistencies with the spiders will yield inaccurate results. Not all wolf spiders develop the same, so gripping force and leg contraction can vary between grippers.
There are moral implications behind euthanizing spiders for robotics. The ethical boundaries that necrobotics push in the pursuit of biohybrid systems raise concerns, as opponents say it may lead to the hybridization of mammals and is intrusive to nature.<ref name=":3">{{Cite web |title=How
