Hi, I'm quite new to building a robot and even programming it. I had high expectations when holding the Builder Kit in my hands. But, alas!

The cables for the speaker and the IR-Sensor were missing, the USB cable for charging the battery didn't work so I hat to replace it with one from my stock - charging works now. One motors was did not move a bit for calibration. Even after assembling it an running an initial "Dance" it didn't move - a handicapped robot with a stiff leg...

During assembling I've encountered more problems. The notch/cavity on the legs is not big enough to hold the little plastic things for connecting to the motor. I had to file them down in order to fit them into the gap. The same issue was with the crosses that have to fit in the legs. I've cutted them to the correct length but they were as well way to wide for the pre-made slot. But they are now somehow crooked.

Overall I'm quite a bit disappointed.

To make Otto work I had to order cables and a new motor from eBay. I have ordered at the same time here from Ottodiy the sensor kit. I'm a bit worried now about it's quality when it arrives...
