Powering the unit became an issue. However with a little troubleshooting we discovered the issue. The manual states you need two 18650 Li-Ion batteries in the quadruped and also in the remote. What the manual does not state is that these (in the quadruped) MUST be UNPROTECTED batteries. IF you use protected batteries, you will most likely experience issues. We initially used unprotected purchased off amazon and the unit would NOT power on. So thinking I got bad batteries I ran to radio shack and purchased a set there which was protected. I honestly wasn't thinking protected/unprotected at that time. The unit powered on, so we pressed on. We tested all servos as directed without issue. It wasn't until we'd finished the quadruped and plugged all servos in to set to configure them to center that the unit sounded odd. Unsure as to what to expect there, we continued and then once we were supposed to calibrate discovered the unit will just turn on and do nothing. The blue power light would quickly flash and nothing. This is the issue with Protected batteries. We removed the protection to validate and the unit did turn on, blue light on, legs began to move. Immediately powered off and removed the battery which began to smoke and was thrown outside. DON'T DO THIS!
We purchased another set of unprotected batteries and again nothing happened. I then purchased an xtar VP2 charger and it showed the batteries were fully charged. FIX: The unprotected batteries did not have a nipple on the positive end. It's a flatter surface (on both sets and most I see online). Due to that, the batteries are not making a full connection in the battery housing. Pushing the batteries forward in the housing made the light come on but it went out when the pressure was removed. I swapped holders from the remote and the quadruped and pushed the batteries forward then let go. They have held and we were able to complete the project successfully. Long and short, when you purchase UNPROTECTED 18650 batteries try to find a set with the nipple on the positive end. Otherwise with a little adjusting, you should be able to get the proper power to the quadruped. (Note: Protected batteries work just fine in the remote).
Another thing to consider. During the build process, you connect the rocker arms with 8 little screws. Later in the instructions it states to align the thigh parts. I noted a few of the thighs are slightly angled and then realized later that all the teeth weren't in the same positon. Had I only put two screws (vice all 8) into the rocker arms, I could have removed the screws, rotated the rocker arm, and then stuck the thigh on again to get really good alignment. Then screw the remaining screws in place. (Too much work with 8 screws in place on each rocker arm.). Read through the instructions first, and you'll see how these are connected and it may help you later when you are working with the alignment of the quadruped.
Once we got through the troubleshooting stage, my son has had an awesome time playing with the Dancing and Crawling mode. The calibration steps were a little above him, but he's learning some coding which is a bonus.
Replacement servos with round rocker arms have arrived and kit fully assembled. Arduino code compiling issues corrected by installing older version 1.6.8 of the Arduino IDE. While crawler is going through the provided "dance" moves smoothly, I only get very erratic and intermittent movement from remote. Still got an issue but will raise my rating by one star.
