RHTC - 560 Hunter Trainer The RHTC - 560 Hunter Trainer was a training / gladiatorial droid system developed by Rodian D - Tec to help track and eliminate prey during the Imperial Period . Description . Master Control Unit . The RHTC - 560 system consisted of one bipedal control unit and around ten smaller hunter trainer drones . The master controller unit was bipedal in shape and form ; resembling both its Rodian creators and an armored arachnid . Towering at a height of 1 . 8 meters and armed with sharp claws on both their hands and feet , these droids excelled in their role as gladiatorial / training droids . The RHTC - 560 master unit ' s ferocity in combat was further reinforced by its speed and agility . Its advanced programming also gave it access to some of the latest stealth and evasion techniques available in its time . Since it was also required to interact with its masters , the controller unit was equipped with a vocabulator , a wideband communications transceiver , and a sensor array system . Meanwhile , a scomp link access port allowed the droid to pilot the drones through any obstacle as well as to replay recordings of its activities while being debriefed following a hunt . Some were even modified to carry two forearm - mounted blasters . HT Drones . In stark contrast to the towering controller units , the HT drones were small droids about half the size of an R2 - series astromech droid . Each drone came with two forward retractable arms for manipulating objects and two hind legs for traversing over the jungle floor . They were circular in shape and also came with an anti - gravity repulsorlift unit for hovering over their targets . To enhance their effectiveness , they were equipped with stun blaster s . For operations in the dark of night or the depths of a jungle , these drones were equipped with high - intensity searchlights to locate their prey . As with most other simpler droid designs , these drones lacked independent personal programming and were entirely controlled by their control unit within a range of 50 km which impaired their effectiveness in long - range hunts . However , this was compensated by the RHTC - 560 system ' s creativity subroutine which allowed it to remain operational even in a wide range of tricky situations . Even if the control unit was submerged underwater , it was still able to command its associated drone units . History . The RHTC - 560 Hunter Trainer system was originally marketed locally by Rodian D - Tec on the Rodian homeworld of Rodia to suit the native Rodian appetite for violence and combat . Their customers ranged from bounty hunters , to the various Rodian clans which used them in both their clan wars and hunts , to even the dictatorial Grand Protector Navik the Red . It was alleged that the Grand Protector ' s RHTC - 560 system had been modified with lethal disruptor cannons for used against his captives in competitions . Throughout the Imperial Period , their popularity was sufficient enough for the series to be marketed offworld beyond the confines of Rodia . With 5 , 000 credits for each control unit and another 2 , 000 credits for each HT drone , the series was economical enough for many non - Rodian bounty hunters , as well as local planetary militias and police academies . Three were also given to the captain of the " Anya Karu " , Aron Harcourt . They would later fight , and lose to , the bounty hunter Boba Fett .
