Substitute Robots

Substitute Robots (also known as Reserve Robots) were robots that were on standby if another one pulled out. There were several substitute robots that were used over the course of the series, although there were more that didn't get to be used. The circumstances for these robots appearing on the televised show vary. Steg-O-Saw-Us was the most successful, the only one to make it past the heats.

Although many substitute robots were used over the series, they were rarely acknowledged as such on the show itself. Only four robots were actually addressed as replacing a previously intended competitor.
