In humans there appear to be multiple attention mechanisms distributed across the sensory modalities, executive control, and cognition. Similarly, A.s.a. H. has required the incorporation of multiple attention processes. Just how many are required?

Should different ways of representing concepts and different types of deduction system be used on different levels of a knowledge hierarchy? Certainly physics and biology use different sorts of representation and different practices. In a few of my experiments with Asa H I have employed multiple different similarity measures. When forgetting is used to prune less useful cases/concepts I sometimes find one similarity measure dominates on one level of the abstraction hierarchy while a different similarity measure dominates on another level. (By dominates I mean gives results having the highest utility measures.)

The jimu line of robots available from Ubtech are made from snap together components that are compatible with my pain subsystem. The holes in Vex IQ and jimu parts are almost the same size. You can use either Vex IQ pins or jimu pins to join jimu parts to Vex IQ parts. The Vex IQ pins are a bit more snug and probably work the best. Some hole spacings on jimu pieces are identical to spacing on Vex IQ which also helps combine the components. You can drill out the holes in jimu parts so that they will accept Lego pins. You can then join jimu parts to Lego parts.

We have owned 4 or 5 Roombas, each a different model. My original intent was to follow Tribelhorn and Dodd (Evaluating the Roomba..., 2007 IEEE Conference on Robotics and Automation) and Kurt (Hacking Roomba,Wiley, 2007) and use Roombas as a robotics platform for A.s.a. H. But with the development of my pain subsystem this became suboptimal (as it is also with Vex EDR, Meccano, 3Pis, and the like). So now our Roombas simply clean the floor (see the last picture in my blog of 16 January 2012 ).
It is easy to hack the Thames and Kosmos CB1 core controller so that switch inputs can receive signals from my pain subsystem. Multiplexers can allow one to identify different pains having different points of origin if that is desired. The CB1 outputs could be used to control the multiplexers (select lines).
