# Summary of #hplusroadmap IRC Discussion (April 19, 2010)

• Discussion of "bush robots" (fractal branching manipulators) focused on fabrication challenges, with participants noting that tentacles might be easier to fabricate than ball joints and that nanoscale precision isn't necessary for useful applications.

• Participants discussed Misumi components, particularly their structural beams and other industrial components that could be useful for fabrication projects.

• A DIYbio survey was shared (http://diybio.org/survey/), with commentary that venture capital firms were showing interest in DIYbio groups according to a Lux research report.

• A link to Sikuli (http://groups.csail.mit.edu/uid/sikuli/index.shtml) was shared, noting it uses OpenCV for visual automation of GUI interactions.

• NASA's Robonaut 2 was discussed, with participants noting the impressive articulation of its hands (http://www.nasa.gov/mp4/445566main_NE00@Robonaut2.mp4).

• Anders Sandberg's work on "neuroselves" was shared via Giulio Prisco's blog (http://giulioprisco.blogspot.com/2010/04/telexlr8-anders-sandberg-on-neuroselves.html).

• Brief discussion of delta-v budgets for Earth-Moon space travel, with commentary on the limitations of Wikipedia's presentation of this information.
