I have built a 1 HV
It has two Gyros
I can get all the standard moves to work OK.
Except the Kick moves.
What specifically happens? Can you describe it, or provide a video clip? What are the motion file names?
I have tried moving the home position to move weight left/right forward back and played with the gain of the gyros within the ranges described.
The gyros can only correct the robots servos back to what they think are the right positions. They have no absolute reference. If it is setup correctly then it will perform the sample motions without the gyro correction.
Has anyone got these moves working without editing the moves ?
I don't mean to sound sarcastic, so please don't take it that way. The manufacturer had the sample motions working without editing the moves. And they test them on quite a few robots before they start shipping. During the demos they have from 4 to 6 doing the sample motions all running the same unedited data.
I have assumed that if I buit and set up the robot corectly then all the standard moves would work most of the time.
That is a good assumption. They will. However, you do need to go back and recheck the Trim Position from time to time since the setup will change as the robot is used.
The kick moves are no where near working but all the rest work real well.
By the standard moves I mean those included on the CD.
I tried to told the non kicking foot down to see if I that would help me analysis the problem but I only manages to brak the grey bracket.
If the grey brackets break it is almost always due to stress fractures caused by overtightening or over stress (falling off the table, for example). The screws should be snug, but not over-torqued. Some builders tend to crank down on the screws thinking it will make them more secure, but all it does is stress the plastic.
If you look at the way the brackets are designed to interlock you can see that the screws act basically as a locking/location pin. The mechanical joint stability doesn't depend on the tightness of the screw as long as they are snug enough not to vibrate loose.
Is this normal ? Does he need rubber feet as shown in the KHR book ? Same I can't read Japanese !
Which KHR book?
All the sample motions can be performed with the black plastic bathtub soles.
Time to find the super glue and move that braket to a low stress joint - elbow I guess.
You can try it, but I highly recommend replacing it with a brand new bracket. You might want to buy a few spares since chances are that your other brackets may have stress cracks as well.Statistics: Posted by tempusmaster — Wed May 14, 2008 6:33 am
