A '''Stewart platform'''
'''Synergistic'''. Because the motions are produced by a combination of movements of several of the jacks, such a device is sometimes called a Synergistic motion platform, due to the Synergy (mutual interaction) between the way that the jacks are programmed.
The [[trademark]]ed name "hexapod" (by Geodetic Technology){{Citation needed|date=June 2010}} was originally for Stewart platforms used in [[machine tool]]s. However, the term is now used for 6-jack platforms outside of the machine tool area, since it simply means "six legs".▼
'''Design - Gough and Stewart'''. This particular six-jack layout was first designed by V E (Eric) Gough (UK) and was operational in 1954, the design later being publicised in a 1965 paper by D Stewart to the UK Institution of Mechanical Engineers. Although the short title "Stewart Platform" is now used for this jack layout, it would be fairer to Eric Gough to call it a "Gough/Stewart platform".
▲'''Hexapod'''. Because the device has six jacks, it is often also known as a ''hexapod'' (six legs). The [[trademark]]ed name "hexapod" (by Geodetic Technology){{Citation needed|date=June 2010}} was originally for Stewart platforms used in [[machine tool]]s. However, the term is now used for 6-jack platforms outside of the machine tool area, since it simply means "six legs".
