Not totally sure what you're wanting from this... but if I'm reading correctly then this should work: 

while (<DATA>) {
  /\/([^\/]+)\d$/;
  print $1."bot\n";
}

__DATA__
## /loc1/loc2/loc3/848xxxxxB01_d_1
## /loc1/loc2/loc3/loc4/848xxxxxB01_d_1
## /loc1/848xxxxxB01_d_1

Obviously here I'm replacing your input file with the __DATA__ block for ease of example and naturally you could change the print $1."bot\n"; to print MYOUTFILE $1."bot\n";.
