    • Nonholonomic systems via moving frames: cartan equivalence and chaplygin hamiltonization 

      Ehlers, Kurt M.; Koiller, Jair; Montgomery, Richard; Rios, Pedro M.
      2005
      A nonholonomic system, for short “NH,’’ consists of a configuration space Qn, a Lagrangian L(q, q, t), a nonintegrable constraint distribution H ⊂ TQ, with dynamics governed by Lagrange-d’Alembert’s principle. We present ...

    • Self-propulsion of N-hinged 'Animats' at low Reynolds number 

      Araújo, Gerusa Alexsandra de; Koiller, Jair
      2003
      Optimal locomotion of micro-organisms (on a small Reynolds number flow) can be regarded as a sub-riemannian geometry on a principal bundle with a mechanical connection. Aiming at robotic applications, flagella are modeled ...
