Protocol: 3D architecture–robotics synergy for ≥90 % harvest reachability in high-density pear canopies

This registration covers the systematic review protocol for the paper “Towards ≥90 % Harvest Reachability in High-Density Pear Canopies: A Quantitative Review of 3D Architecture–Robotics Synergy and Trade-offs”. We followed a quantitative adaptation of PRISMA 2020 and pre-specified search blocks, inclusion/exclusion criteria, and meta-analysis code. The final protocol is provided as a PDF in this component.
