In 2001, Dr Robot began what would become its longest-running research project:
develop a dynamically walking bipedal robot that would cost no more than a PC.
Seven generations of robot prototypes have followed and the technology developed
for the HR Project has found its way into many other robots since. Moreover, HRís
patented DURAS architecture has become the standard platform for all Dr Robotís mobile designs.
HR7 is the culmination of four years of bipedal motion research and offers some
fundamental improvements over its predecessor. Original market plans for HR6 were
postponed in the interest of introducing a true dynamic gait to the robot as well
as refining the robotís appearance and functional forms. In addition to unifying
the exterior materials, we gave HR7 five fingers to replace the pincer grips that
all previous HR robots had. More notably, HR7 uses a new recharging technology that
keeps charging time under 5 minutes for standard use (2 to 4 hours operation). HR7ís
sense of balance is vastly better than that that of HR6, but, like HR6, if it trips
and falls, it gets back up again.
