KHR 3HV Humanoid Robot Kit - Rev 2
The Khr 3HV Rev 2, improves on the sucessful KHR 3HV design with the improved 2552RHV servos and a new Dual USB Adapter HS.
The new servos feature ICS3.5 protocol making them compatible with Serial or PWM communication. In addition the new Dual USB Adapter HS lets communicate with the servos directly to configure and fine tune the servo behaviour (including the new features added in ICS 3.5).
|A tall, extensible KHR
The base robot includes 17 servos (DOF) + 5 Dummy servos that allow for
easy expansion up to 22 DOF. The robot is assembled from the
start with the 22 servos in place (17+5), a feature unique in the
The long arms and legs (achieved with the use of
22 servos) make for the tallest KHR ever, with an exceptional
|RCB-4HV and ICS 3.5
The RCB-4 controller board enables the control of up to 35 serial servos.
It is compatible with the ICS3.5 servo protocol and a wide range of options parts. The board also includes several extension ports (10x A/D and 10x PIO) which enable the use of a wide range of sensors and extension options.
The KHR 3HV Rev 2 uses the latest KRS-2552RHV servos,
that feature ICS 3.5 interface. They can operate in a Daisy Chained serial protocol
allows the connection of several servos in single chain reducing the
number of cables and simplifying connection.
KRS-2555RHV Servo Specs:
The new servo is slightly smaller than KHR-2HV servos and offers increased torque and operating angles.
The use of metal gears improves servo reliability and strength.
ICS 3.5 servos operate at 1.25Mbps standard for fast communication and can also be configured to operate with a PWM dignal (new in ICS 3.5).
A design to ease and to smooth the folding of the knee has been enhanced. Thanks to the new design, the robot can retract and stand up faster from a sitting pose.
The use of materials such as aluminium, polycarbonate and ABS with incorporation of Glass allow for lighter yet robust frames.
|Improved Angles and Servo Arms
Thanks to the strengthened servo arms, the robot is more resistant to shocks and thus become a real ally during robot competitions.
The main frame cover is made out a light ABS plastic. It is easy to change to another body frame for customization and modding.
Thanks to the slim body, the user can handle the robot more easily.
The robot comes fitted with five dummy servos in strategic places for extension (chest/torso, arms) and is assembled with these static servos in place for the first minute to build the robot's tall and slim figure.
You simply need to replace the dummy servo with the optionally available KRS-2552HV servos for added DOF.
This new faculty enables the user to easily add new degrees of freedom and set up new capabilities for the robot.
The new design of the servo head makes it possible to assemble it naturally to the shoulder. It is meant to give the robot a more intrepid style.
|Bath tub Sole
The new design of the sole gives a more secure walk.
The new design of the back pack enables an easier maintenance of the robot. The user will be able to easily add sensors and motors.
A nickel battery 10.8V-800mAh has been included.
With the "fast charger" included the battery takes only one hour to charge.
|New Software - Heart to Heart 4 Rev
Heart to Heart software 4 has been revised with the release of the KHR 3HV Rev2, offering an even more user friendly interface. It should make the creation of new Motions and new Behaviours simpler and more efficient.
The software also includes "project management" features for improved collaboration and performance in team competitions.
KHR 3HV Rev 2 is backwards compatible with most of Kondo accessories for previous KHR editions:
