PCB redesigned, to fit inside an 8cm cube, the idea being that it fill be the size of a miabot inside a hamster ball size ball, driving about.

The PCB now use an xbee module to communicate with the ouside world, with the old reciever transmitter pair connecting the outer ball, containing the hr, gsr temp and US sensors, with the inner ball, for information transmission to the drive board then to themac

the mac has a usb xbee resiever, being sent today hope=fully, to be recieved today or tomorrow, a board of 10 were bought as it was more cost effective to buy 10 half made, then source components, than it was to get 4 boards which are fully built.
