Ilia probe
The Ilia probe was an avatar of V'ger, a sophisticated android with the memories of Lieutenant Ilia, whom V'ger had previously abducted from the . The probe was designed to interact and inspect the carbon units it saw as infesting Enterprise. 

By 23rd century medical standards, the Ilia probe was an impressive construct, as it replicated the body of Ilia down to the smallest detail. Noted technological components included "micro-miniature hydraulics, sensors, and molecule-sized multi-processor chips." More impressively, it contained 
osmotic micro-pumps, allowing "even the smallest body functions are exactly duplicated," including every exocrine system, and even eye moisture. Additionally, memory patterns in Ilia's brain were replicated, allowing the crew of the Enterprise to attempt to revive the memories and emotions of the navigator through stimulus. 

The Ilia probe was presumably destroyed when Commander Decker merged with V'ger in order to stop the machine from destroying Earth. ()
