We provide Parametric Robot Control in three versions — Windows, macOS,
and a cross-platform Developer build for all .NET platforms. For most users we recommend
the most recent release below. At the moment, no stable release is available as PRC is in heavy development.
The Manual Download section contains the most recent releases as well as an archive of older
installers — if you require a specific version, contact us. Please refer to
docs.robotsinarchitecture.org for support.

Version
An experimental Docker image is provided at
jbraumann/prcserver.
Map ports 5001 to 5001 for basic functionality. Real-time interfaces may require more ports to be opened.
Release Notes
Important: On macOS, if you are using a version older than mid-April 2026, you may need to re-install your certificate if you encounter errors! This is a one-time action — leaf certificates are now generated automatically for every new version and do not need to be re-installed manually.
NEW
Universal Robots: Polyscope X programs are saved as a .script file for the Script Manager (Polyscope X 10.11 or later).
UR RT: optional "Refuse While Busy" setting - a new task no longer interrupts a program the robot is running.
Grasshopper: a Core with only a robot connected shows the robot at its home position.
IMPROVEMENTS
Realtime drivers (UR RT, NEURA RT, KUKA mxAutomation): applying settings runs the last program again only while Run is on
Robot data: KUKA KR 6/10 R900-2 with a more accurate mesh.
Grasshopper: smoother shading of robot meshes.
Grasshopper 2 releases its robots on the server when a definition is closed.
C# library: the client returns PRC types.
