This is not true. An increase in weight causes an increase in normal force, which directly leads to an increase in traction. Increased weight will not lead to increased acceleration however, as mass cancels in the equation for acceleration in a traction limited environment.
Basically, any robot with all wheels driven and no additional thrust mechanisms (props) should have the same maximum acceleration rate. The advantage to a heavier robot will be in a collision/pushing match.
