FAQ

1) Why doesn't the motion file I created with the simulator transfer perfectly to my robot?
Each robot has a slightly different initial and standing position mainly due to the differences in the Servo Hone middle-position settings so motion files will usually require minor tweaks in order to transfer them from one robot to the another.

2) Why does the motion file on the CD, called "Sample_FWD.csv" make my KHR-1 walk backwards ?
There are a few reasons that can cause the inverseness. The first is that the servos can be set to act in "reverse mode" using the ServoManager software. It is unlikely that they may have come reversed from factory. The second reason is related to the fact that KHR-1's legs and other body parts can be assembled inside-out in more then one way, other then what it says in the manual. You can see such a different configuration in the IXS link on the video page at our videos page. It may be that Kondo's engineers recorded the motions whilst playing with various configurations of KHR-1. Another reason can be that the wiring is wrong and your left side servos are normally supposed to be controled by other channels. This is easily fixed using excel spreadsheet to edit the .csv file and moving the columns around to fit your settings.

3) Can 2350ICS servos replace the 786ICS servos that come with the KHR-1 kit?
No. The KHR-1 can not have the 8.7kg-cm servos replaced by 20kg-cm servos because of the likely structural damage that it may incur.
However, there is a new robot kit that has just come out and is very similar to the KHR-1, called YDH. It is composed of 21 x 2346ICS servos instead of the 17 x 784ICS (ie: 21DOF). Its aluminum structure is more robust and fit to handle the huge torques.
Update: YDH is not available any more..

4) How can I connect a continous power supply to the KHR-1 ?
The trick is to push the battery charger plug into the back side of the battery female socket. You plug the battery to the RCB-1 connector and then plug the battery charger into the back of the battery plug socket.

5) What kind of continous power supply is needed to keep the KHR-1 going?
The KHR-1 with 17 or 21 servos requires up to 10Amps of continous power supply to operate.
