NASA Space Apps Challenge - Bouncy Ball - Zero G Bee.

NASA Space Apps Challenge in Cambridge over weekend of April 11. See tweets @AlbertPutnam. Many thanks to: Binnovative for heading. Hack/reduce for hosting. IBM for facilitating. Local sponsors for supporting. NASA and ESA overall. Sorry other events and logistics had to share the time.

Looked at doing something with space craft thermal power consumption, but could not find way to data at ESA Venus Express. Seemed like a great place to use some data mining tools from IBM BlueMix.

So instead chatted with people about other ideas, and after awhile came to this Bouncy Ball project for the Zero G Bee challenge.

The Bouncy Ball approach is sort of a hack within a hackathon. Namely a reframing of the problem really: Roadie in space. Social model of robot which needs help. Padded with Zorb.

The core work is not about electronics or code, so it made it "difficult" to submit that. But the expression of target intent needs facilitation and that is where a screen module packed inside the ball with the payload would come into play, with input UI using natural language ala Watson, and output UI using facial expressions and language/text like other social robots.

Some one suggested that there would not be enough humans onboard the space station to make social forwarding work... Maybe not. Then the problem could be converted to stewards or doorman bots (arms) at the interconnect points within the station to help the bouncy balls (or anything) along.

BACnet and Internet of Things for Systems Managers.

How are BAcnet, Internet of Things, and their requirements, features and users, related? Apologies to Toby Considine. Just cannot get over Internet of Things.

In building automation who does one try to serve? When one goes through the list - owners, operators, and occupiers - it usually comes to the facilities managers - and being a bit more general about what automation we might be talking about - systems managers. System managers are beset by fear. Fear of disruption from all sorts of directions. System managers crave stability and reliability foremost. Efficiency and optimization comes after that. Systems managers are faced with monumental tasks.

In the Internet of Things wave, almost every facet of how a systems platform goes together are up for consideration... security, manageabilty and interoperation are current hot topics. Alan Messer of Samsung showed a great list at a recent MIT IoT event.

Turns out BACnet, as a lingua franca for building automation, has many of the facets well under control.
Especially well covered: clear semantics, great model and defaults, topology definition, simplicity with extensibility, system setup strategies part of architecture (like discoverability).

Rosetta Stone - translation - common understanding - lingua franca

And there are things BACnet can be served well by from watching and following IoT. Especially techniques in:
  • Location awareness.
  • Wireless communications.
  • Energy harvesting.
  • Social information input.
  • Raw simplicity (dumb things, simple networks).

Motivations - Monetary Rewards, Morals, Social Pressure.

Found this in Greentech Blog about how monetary rewards trump morals.

Always interested in a contrarian position. The above thesis flys in the face of many recent findings regarding the mechanics of social interactions.

So which is a better model of reality? Perhaps they both are because there is a subtle difference. They make different assumptions at the outset. Morals are perhaps more of a personal construct or rule of thumb amassed from societal pressures internalized by the individual. Pure raw local group pressures are perhaps more direct. And morals (with a very narrow definition) might lag pure group pressure. That is perhaps not saying it with all the nuance needed. Alexander Pentland's book Social Physics maybe is a good place for an overview of the raw peer pressure point.

In brief - moral suasion directed to the individual as in the Japanese study cited by Greentech is perhaps orthogonal to pure direct peer pressure. And there are issues with the Japanese study regarding "top down control" of the programme, versus the local social aspects of how communities might apply pressure locally.

So there are perhaps three ways to motivate: (in the order they seem most effective).

Direct and immediate social pressure from your immediate local peer group. This has been found to stick. Even after the "setup", "message" or "incentive" is removed. It "becomes" morality. It is like a sort of ghost memory of the motivation pressure. And are apparently roughly a half order of magnitude more effective than monetary rewards.

Positive Peer Pressure - directly from local group

With monetary rewards the problem is that morality and social pressures kick back in after financial incentives are removed. Monetary rewards are effective while they are ongoing, but their imprint fades (and sometimes even goes negative) after the incentives are removed. There is conditioning for expectation of reward. Rewards do not, by themselves, create morality.

Moral suasion or suggestions based on existing moral baselines. Again if the suggestions are removed, then individuals revert to their easy self serving behaviour. We forget. We rationalize.

The keys seem roughly as follows:
Socially based best practice approaches are self serving. If you serve the group well, if you give well, then the rewards to the self are socially large. Monetary or economic incentives come next. And they are followed in effectiveness by appeals to an existing general (perhaps somewhat nebulous) moral framework.

So how might this translate into practice? Back to the Japanese example there should have been four groups in the study: The three cited - control, moral suggestion, and monetary as well as one more. The last is slightly more tricky to construct - but not much more. It is an incentive based on feedback of how well six to ten of your immediate neighbours are doing. You are given "value" (okay generally monetary, but it could simply be praise or goodwill) based on how well your peer group does in aggregate. And there are constraints. You have to regularly communicate face to face with your "neighbours". From this point of view your neighbours may not be physically adjacent but a group formed of your co-workers or firends (or family) (with similar target infrastructure of course) with whom you interact every day.

Pentland's tidbits on social physics are rather thought provoking. Ineffectivness of loose social network pressure (Facebook) was a shock, but not exactly a surprise once one thought about it a bit. Moral pressure, loose nebulous social pressure, and direct local peer pressure are often lumped together,
but can be very different things.
