A typical Backhoe, for example, has 3 degrees of freedom.

Rename to "mechanics"

The word "engineering" is too diffuse here. The title should be Degrees of Freedom (mechanics). For example, the reference to the Elec Engg concept of Antenna DOFs is perhaps more appropriate in the DOF(physics) discussion than here.

what about 'statics'? --Leladax (talk) 11:39, 8 February 2008 (UTC)[reply]

Probably not statics since d.o.f. implies motion. Also statics and dynamics are generally associated with engineering mechanics. Keeping it as "mechanics" is probably a more appropriate choice. - Jameson L. Tai ^{talk ♦ guestbook ♦ contribs} 07:51, 4 February 2009 (UTC)[reply]

Rename to "motion"

The degrees of freedom in this context refer to motion, so should be renamed in this way. A 2D motion has two degrees of freedom for example like a land vehicle and aircraft has 3 degrees of freedom. --89.122.167.251 (talk) 12:32, 5 April 2011 (UTC)[reply]

Oppose See WP:COMMONNAME. "Degrees of freedom" is the term in common use. Note that rotations also count as freedoms, so aerobatic aircraft have six degrees of freedom, not three. Andy Dingley (talk) 12:50, 5 April 2011 (UTC)[reply]

Degrees of freedom of course, but {motion) should be a disambiguation paranthesis. The free degrees of freedom are probably refering to translation, not rotation.--188.26.22.131 (talk) 15:39, 5 April 2011 (UTC)[reply]

Examples of Degrees of Freedom in Robotics

I think it would be highly beneficial to include a more applied example to this article (or wherever is most appropriate) - something like http://www.robotics.utexas.edu/rrg/learn_more/low_ed/dof/ - or at the very least, link to such a resource in the external links. —Preceding unsigned comment added by 91.104.137.129 (talk) 22:41, 25 April 2008 (UTC) Agreed, I can imagine the current picture being quite confusing for the average joe. 78.82.140.122 (talk) 00:50, 16 July 2009 (UTC)[reply]

Proposed revisions

Degrees of freedom of a mechanical system is the number of parameters that prescribes its configuration. It is also the dimension of its configuration space. If the mechanical system consists only of holonomic constraints, such as a system of articulated links that forms a linkage or robot, then the degrees of freedom is defined by the mobility formula. Discussion of these topics should be a useful addition to this article. Prof McCarthy (talk) 17:26, 2 January 2012 (UTC)[reply]

I increased the importance because it is difficult to talk about robotic systems without considering their degrees of freedom. Also while still in the beginning this article does not seem to be a stub any longer. Prof McCarthy (talk) 06:47, 13 January 2012 (UTC)[reply]
