# Key Points from #hplusroadmap IRC Discussion (May 28, 2010)

• Kanzure acquired a Unimate PUMA500 Robot Arm (model JR3 67M25A-U560), sparking detailed technical discussions about retrofitting industrial robotic arms with modern control systems using Mesa control cards rather than simpler Arduino solutions.

• Participants shared resources for PUMA robot retrofitting, including CMU documentation and the Robomo project, with specific hardware recommendations totaling approximately $517 plus power supply and accessories.

• The conversation highlighted sophisticated engineering considerations in robot control systems, particularly the challenges of signal integrity over long wires near magnetic fields and the need for local processing with robust communication protocols.

• Kanzure mentioned discussions with Eric Michaud about creating an open source sub-micron double-sided PCB automation setup with a potential $100k prize, showing the community's interest in democratizing advanced manufacturing.

• The BioCurious collaborative biology lab space was discussed, with a presentation link shared, demonstrating early community interest in accessible DIY biology workspaces.

• Participants noted scientific developments in RNAi technology providing protection from Ebola, reflecting the channel's tracking of cutting-edge biotechnology research.

• The group discussed repurposing liquidated lab equipment, including modifying thermocyclers with AVR microcontrollers and HTTP servers, showing the community's approach to obtaining and upgrading scientific equipment.
