The Chebyshev's Lambda Mechanism is a [[cognate linkage]] of the [[Chebyshev linkage]].
 
The linkage was first shown in Paris on the [[Exposition Universelle (1878)]] as "The Plantigrade Machine".<ref>http://mech.spbstu.ru/Dzenushko_Dainis:_Walking_mechanisms_survey#The_Chebyshev_Walking_Mechanism</ref><ref>{{cite web|url=http://www.etudes.ru/en/etudes/stopohod/ |title=Archived copy |accessdate=2014-11-16 |deadurl=yes |archiveurl=https://web.archive.org/web/20141129015429/http://www.etudes.ru/en/etudes/stopohod/ |archivedate=2014-11-29 |df= }}</ref>
 
The Chebyshev's Lambda Mechanism looks like the Greek letter lambda, therefore the linkage is also known as Lambda Mechanism.<ref>{{cite web|url=http://www.etudes.ru/en/etudes/stopohod/ |title=Archived copy |accessdate=2014-11-16 |deadurl=yes |archiveurl=https://web.archive.org/web/20141129015429/http://www.etudes.ru/en/etudes/stopohod/ |archivedate=2014-11-29 |df= }}</ref>
