I will post comments on my experience in assembling my Manoi here. I learned a LOT. Primarily, that I do *NOT* follow directions near as well as I thought!
ONE MAJOR KEY is to zero the servos **BEFORE** you assemble. This is the only way they rotate to the center position for you to attach all the horns and stuff. Be sure NOT to rotate the armature of the servos until the horn is IN place. Using the calibration labels is useless unless you do this.
AND, the calibration labels stick on, PLUS have a clear protective plastic sheet over the TOP as well as the adhesive white sheet on the bottom. Remove BOTH.
1. Install the USB serial port driver. Just put the CD in, connect the cable (the LOOONNGG servo cable) to the PC. When prompted, tell Windoze to Search the CD drives for the drivers. It goes through the process twice in a row, I don't know why, but it works. Mine was COM3:.
2. Start the H2H english version. Check SYNC set the COM port. Mine was 3. Click the POS and then click in the canvas to make a POS1. Double click the POS1, and right click CH1. When you select SERVO, the servo connected to the Controller on CH01 should move. The slider should make it spin. If it does not, power down the RCB and back up, and right click, select NONE, then right click and select SERVO.
This took me 20 minutes to get it to work. I had to change servo cables and servos on that channel, and eventually, for no reason, it started to work.
3. Then go through every servo hooking them to that CH1 and set them to 0. Some will spin a bit, some will just stutter a bit, but that will center them. These servos only move a limited amount, so you MUST put the horns on while they are centered, or you will lose range of motion.
I zero'd and all looks good.
Once the Bot is assembled, you want to go BACK and use the TRIM to save a trim value for all the servos to get the horn exactly centered.
The biggest issue I had is that H2H3 software locks up when I am trimming to get them centered. The program uses 99% of the CPU and has done this several times. I set the trim offsets for the first 7 servos, and saved them to a file, but opening the file does not recall those trim settings...
This software is not exactly commercial quality, not that I expected better. It also cannot remember the serial port from invoke to invoke.
All the servos are operational and I am trying to trim then, then install the gyro. That is the next challenge.
I suggest anyone consider getting the three additional degrees of freedom. Two for the arms and one for the waist. I would like to do that before I get too far, and I see they are documented (so to speak) in the docs.
Showed me that I do not follow directions as well as I thought I did. The first horn construction episodes were horrible, as I missed a few LITTLE details. After re-doing that *twice*, I got the hang of double-checking everything. The MOST aggravating thing is that the stupid diagrams do not consistently refer to the parts by servo number, but refer to them by L and R. I needed to mark them L and R as they were constructed. Overall, the physical construction was probably about 8 hours.
Overall, decent experience.
I got the Hozun Japanese JIS standard screwdrivers and they REALLY helped. Go to eBay and look for the Store of IKASINC
http://stores.ebay.com/Ikasinc The four drivers are $16.50. I used to #0 for everything except the 3- screws where I used the #1. A motor driver to EXTRACT screws is OK, but DO NOT USE ONE TO tighten!! The screws into the servos are VERY suceptible to stripping the plastic. The screws into the resin parts work real well. It is VERY easy to strip the heads of the 2x15 screws, so press hard straight down while tightening.
I think I will make a CARE PKG zip file of ALL the files I have collected as a one-stop collection for anyone stupid enough to try this!
It was REALLY fun and challenging - so far a GREAT experience. I am VERY excited to see it do more than twitch...
More to come...
