M27 Explorer, walking, door opening, moving robots & Antenna, Flashing Lights.

This is the third version of my M27 Explorer project. It uses my simple 4 leg walking design using a 1;90 TT gearmotor that also rotates the antenna.
I use a mechanical sequencer that uses a N20, 15RPM gear motor to open and close the side door.
A 555 timer is used to set the walk time before enabling the door open close function.
Operates from 2 AA batteries, with a voltage boost device to feed the 555 timer a clean 5-volt supply.
