  We consider an active, stochastic microscopic model of particles suspended in
a fluid and show that the coarse-grained description of this model renders odd
viscoelasticity. The particles are odd dumbbells, each featuring a robotic
device as the bead, which exhibits a particular torque response. We show that
this model can be macroscopically treated as a viscoelastic fluid, analytically
calculate the coefficients of the corresponding viscoelastic model, and
corroborate the results using molecular dynamics simulations. This work
provides a unified analytical framework for several experimental and numerical
setups designed to elucidate odd effects in fluids.
