A highway robber is any mechanism that can retrieve a signal from a spaceship lane while allowing spaceships on nearby lanes (even those a single lane away) to pass by unaffected. In practice the spaceship is generally a glider. The spaceship is removed from the lane in question, an output signal is generated elsewhere, and the highway robber returns to its original state. A competent highway robber does not affect spaceships even on the lane adjacent to the affected spaceship stream, except perhaps during the highway robber's recovery period.[1]

A stable highway robber with repeat time 878 was assembled by Chris Cain in 2016,[2] with an update by Entity Valkyrie in January 2019[3] to simplify the extraction of the output signal. A simpler highway robber with improved clearance and repeat time 876 was constructed by Louis-François Handfield in May 2020,[4] with subsequent improvements made by Goldtiger997.[5] The next version made use of the Bandersnatch to reduce the repeat time to 863 ticks.[6] On June 23, Goldtiger997 posted a larger staged recovery highway robber with a repeat time of 742 ticks.[7]

A stable highway robber with 742-tick repeat time,
allowing gliders to pass by on the same lane 47+ ticks after
the activating glider. There are three possible glider outputs,
but two of them are awkwardly close to other glider lanes.
