The 210/220 charger extensions are two pieces. A front mounted
tower base, and rear-mounted alignment circle. Images and
dimensions are shown to the right.
The correct shades of blue &
green, plus the height & position of the tower and disc are all
important. Getting the colors correct can be tricky.
The height and position of the pink ball is very
important for AIBO finding the station, and during final
the disc is too large/small, AIBO could have difficulty aligning
itself. A marginal solution might allow
docking to work occasionally, but fail more frequently than a correct
AIBO bumps into the charger quite a bit while docking, so build
accordingly. Probably the best solution is some thin stiff
cardboard, or hardboard,
with the disc, tower & charger all taped/glued down.
Links to printable 150dpi images of the tower base & circle are
also provided, which may help.
