Abstract: A steering assist system (SAS) for a cart is provided. The SAS may include an activation mechanism, a first actuation mechanism, a first support mechanism, a first linkage mechanism, a first stopping mechanism, and a first engagement mechanism. The first stopping mechanism may be configured to abut the first engagement mechanism to impede or prevent rotational movement of at least one wheel of the cart. The first actuation mechanism may be connected to the first linkage mechanism and the first linkage mechanism may be connected to the first stopping mechanism. The activation mechanism may be configured to activate the first actuation mechanism, causing the first linkage mechanism and the first stopping mechanism to move. The first stopping mechanism may be configured to move between a fully activated position and a fully deactivated position.
