StampBug by Milford Instruments.

Version: Pre-programmed chip kit.

1997, England.

StampBug is an autonomous robot that walks using the alternating triangle method that is the simplest system that allows StampBug to walk forwards and backwards in a straight line and allows left or right turning. StampBug proceeds in the forwards direction until one of his feelers detects and obstacle, making him back up and then turn either left or right depending on which feeler was touched before proceeding on his way forwards again.

Personal note.

This StampBug was my very first robot that I was gifted on my 9th birthday and is still very special to me.
StampBug was restored in 2026 after using a later purchased StampBug as reference to make it fully original again.
The full restoration of StampBug can be seen in my Robot Restoration YouTube channel.
