 abstract = {The isometric fluctuation relation (IFR) [P. I. Hurtado et al., Proc.
Natl. Acad. Sci. USA 108, 7704 (2011)] relates the relative probability
of current fluctuations of fixed magnitude in different spatial
directions. We test its validity in an experiment on a tapered rod,
rendered motile by vertical vibration and immersed in a sea of spherical
beads. We analyze the statistics of the velocity vector of the rod and
show that they depart significantly from the IFR of Hurtado et al. Aided
by a Langevin-equation model we show that our measurements are largely
described by an anisotropic generalization of the IFR [R.
Villavicencio et al., Europhys. Lett. 105, 30009 (2014)], with no
fitting parameters, but with a discrepancy in the prefactor whose origin
may lie in the detailed statistics of the microscopic noise. The
experimentally determined large-deviation function of the velocity
vector has a kink on a curve in the plane.},
