ok finish colouring of the three mother units: Rachel, Angel and Lisa.

Rachel: since she was built first she is a ground type unit the surveys the area when SB's are deployed unreachable places. Also she can be fast on land but medium body armor, if there any threat.

Angel: equip with pincer claws to remove rubble or tear open ship wrack vessels under the oceans. also if an organic life form grabs her she discharges and electrical shock when in contack, though the depth she can reach is only 800 meters, if go any deeper the SB's inside her would have to repair damage holes or retreive her for repairs. She also has a solar panels on her back for recharging, even has sonars in front, under belly and behind.

Lisa: light armored unit and survey on high altitudes. Wings are made with fiber nano cloth for flight and also defences. Her design is to scout threats and give info on each area. SB's will sometime be deploy but when in flight they stay inside her, also she cloaks herself during her flights.

finally, that might be all but think i could've add more weapons to them @.@ but think the design was for them to be surveys and salvage units.
