Sensor upgrades and advanced concept formation

We have taught Asa H some few hundred basic concepts (vocabulary) (see blogs of 14 Feb., 16 Feb., 12 March, 1 April, and 24 May 2013) using the simplest possible sensors (mostly Lego NXT).  We will have to upgrade (see blog of 17 July 2014) in order to learn more complex concepts (like "life", "human", etc.).
