For a recent conference, I wanted to quickly demonstrate some robot control from CAD to robot although we’ve not yet integrated an end-effector. So we came upon the idea of light painting!

As part of the University of Leeds’ annual public engagement event Be Curious, we formed a team of PGRs to bring a hands-on robotics experience to families in the Leeds area. The focus was on robot sensing and human robot collaboration - as part of this, we used a couple of Turtlebots as a demo of some SLAM techniques, and I took on the programming of a PincherX robot arm which was mounted on a table.

We’re running an in-person Summer module as part of the Leeds International Summer School. The module will be delivered over a 2 week period, covering topics including

• History of shell structures
• Parametric design with Grasshopper
• Shell structure form finding techniques and algorithms
• Tesselation and planarisation for panelling
• Connection systems
• Design for digital fabrication

I kept seeing PSO being used in papers to minimise paths for manipulators, so I wrote a quick toy script to test it out. Here’s the results with a Sphere function:
