For inertial propulsion under dry friction, the equations of movement are explicitly derived and provided in closed form, so that such a device can be designed with its parameters computed exactly. For inertial propulsion under viscous friction, on the other hand, there is no closed form for the equations of movement, its dynamics are provided so that a device can be designed using a computer algebra system, as illustrated in the paper.<\/jats:p><\/jats:sec><jats:sec><jats:title content-type=\"abstract-heading\">Originality\/value<\/jats:title><jats:p>The paper demonstrates that an inertia propelled device under dry friction moves in the opposite direction than the same device under viscous friction.<\/jats:p><\/jats:sec>","DOI":"10.1108\/03684920910930321","type":"journal-article","created":{"date-parts":[[2009,2,22]],"date-time":"2009-02-22T00:38:43Z","timestamp":1235263123000},"page":"141-157","source":"Crossref","is-referenced-by-count":2,"title":["The cybernetics of inertial propulsion"],"prefix":"10.1108","volume":"38","author":[{"given":"Alejandro B.","family":"Engel","sequence":"first","affiliation":[]},{"given":"Paul H.","family":"Stiebitz","sequence":"additional","affiliation":[]}],"member":"140","reference":[{"key":"key2022031819540950300_b6","doi-asserted-by":"crossref","unstructured":"Buchi, R., Zesch, W., Codourey, A. and Siegwart, R.
