Welcome: Victor

Aug. 16, 2022

It is my pleasure to welcome Victor Freire Melgizo as the newest member of the ROCC lab. Victor is joining us from the University of Wisconsin Madison, where he designed and implemented path planning algorithms and control barrier functions on UAVs as part of his master's thesis. Here in Boulder,...

Input Saturated Output Admissible Set

Computation of Input-Saturated Output-Admissible Sets

June 20, 2022

Maximal Output Admissible Sets (MOAS) are the set of all initial states and references such that the output response is always constraint admissible . Introduced in [1], the MOAS holds a special place in constrained control theory and is often used in strategies such as Model Predictive Control and Reference...

Human Robot Interaction Experiment

ERG for Safe Human Robot Interaction

Jan. 18, 2021

This video is represents a significant milestone in Kelly Merckaert 's research on safe Human-Robot Interaction. The control laws used in these experiments were developed during Kelly's 6-month research internship at CU Boulder, although their implementation on a physical robot had to wait for her to return to the BruBotics...

Constrained control of a robotic manipulator experiment

ERG for Robotic Manipulators

Nov. 2, 2020

This video, titled "The Explicit Reference Governor for Real-Time Safe Control of a Robotic Manipulator" was presented at the 2020 IROS Workshop: Bringing constraint-based robot programming to real-world applications . These experimental results showcase the interest in implementing an Explicit Reference Governor for real-time constratined control of robotic manipulators and...

Human-Swarm teleoperation experiment

Distributed ERG for Crazyswarm Control

Feb. 28, 2020

This is the support video for the article "A Distributed Explicit Reference Governor for the Safe On-Board Control of a Nano-Quadrotor Swarm" submitted to IEEE Transactions on Robotics. The paper summarizes the work done by Bryan Convens during his six-month research stay at CU Boulder. These experiment represent a significant...

Welcome: Terry

Aug. 20, 2019

Terrence Skibik will be joining the ROCC lab to pursue his PhD in Systems and Control. I met Terry at ACC '18 (and again at CDC '18), where he was presenting the results of his undergraduate research project. He made a lasting impression, so I was very happy when he...

Distributed ERG for Crazyswarm

Distributed ERG for Crazyswarm Control

July 31, 2019

The video is one of the final experiments performed by Bryan Convens at the end of his six-month stay at CU Boulder. During his research stay, Bryan developed a Distributed ERG add-on to the Crazyswarm framework. The addon enables crazyflies to perform real-time formation changes without requiring any form of...

Comic-style illustration of the principle behind Reference Governors

ERG-Toolbox Released!

Sept. 6, 2018

It is my pleasure to announce the release of the Explicit Reference Governor Toolbox (ERGT), now available on GitHub. At the present stage, this MATLAB toolbox can be used to systematically design an add-on unit for the constrained control of linear systems subject to the union and intersection of linear...
