Welcome, new editor! We're very glad you've joined us. Please read The Editor Role. You can look at Getting Started for other helpful introductory pages. It is essential for you as an editor to join the Citizendium-Editors (broadcast) mailing list in order to stay abreast of editor-related issues, as well as the mailing list(s) that concern your particular interests. It is also important, for project-wide matters, to join the Citizendium-L (broadcast) mailing list. You can test out editing in the sandbox if you'd like. If you need help to get going, the forums is one option. That's also where we discuss policy and proposals. You can ask any constable for help, too. Me, for instance! Just put a note on their "talk" page. Again, welcome and thank you! We appreciate your willingness to share your expertise, and we hope to see your edits on Recent changes soon. David E.

Help with HUBO article
Dear Sir,
I'm currently working on the HUBO article & I'm having trouble understanding "closed form inverse kinematics." (pg. 2)
To obtain a closed-form solution of inverse kinematics, the KHR-1 was designed to have a kinematically simple structure. For instance, the hip joint was designed to have a three DOF whose axes intersect at one point without offset distance. The ankle joint also has 2 DOF whose roll and pitch axes intersect at one point.
I kind of get what "inverse kinematics" is, but could you tell me what "closed form" of inverse kinematics is & how that would apply to HUBO's design? Thank you very much. I'm asking help from other Robotics editors as well, in case you aren't around. (Chunbum Park 00:46, 27 February 2009 (UTC))
