Teddy by Helio Fernandes Vieira

This is TEDDY. It was disigned as a kit for school level 
children but i already saw adults playing with it. TEDDY
has a very simple configuration but its very very eficient. 
His function is act like a cricket. When he feels
light he walks finding for a dark place avoiding almost all 
kind of obstacles as walls, fornitures, persons,
stairs etc... and when he reaches there he stops and sounds 
as a perfect cricket. His assemble requires no
soldering its all plugable and there is no possibility to 
invert connections and polarities. He has variable body
collors and some more functions will be included in next 
model. His brain is 2 IC4011 conected in a logical net
that allows the rebot to be able to execute more them 10 
logical functions it means that for each sensor input he
can has more them one possibility as he has 4 sensors in 
total. For sound it uses a sintetized circuit with a
piezzo transducer for a clear cricket sound emition. In 
Brazil it costs 110 USS.
