  Conservative and semiconservative random walks in $\mathbb{Z}^d$ were
introduced and studied in [V.M. Abramov, J. Theor. Probab. (2017).
https://doi.org/10.1007/s10959-017-0747-3]. In the present paper, we extend
these concepts for random walks in $\mathbb{R}^d$ introducing semiconservative
random walks in weak sense and construct such a family of random walks in
$\mathbb{R}^d$.
