Bugfix for #26795 and #26917, Fix a bug that cause the radar sensor to break
Never memset(&ob, 0,sizeof(class)) when there is a constructor, it overrides all memory.
The problem was that the memset(0) was setting the scaling to (0,0,0), the height of the cone became 'infinity'
so GJK would iterate 'MAX_ITER' without converging due to this #NAN value
