comment Optimal covering
It might be helpful to re-state your problem in the following spirit: find an (easily computable) function $f\colon\{0,1\}^k\to\{0,1\}^{k+l}$ such that ${\rm Im}\,f+B_r=\{0,1\}^{k+l}$, where $B_r$ is the origin-centered unit ball of radius $r$. The dependence of $l$ and $r$ on $k$ must be stated very explicitly.
