Both are absolutely correct. That is a good point, and I retried it at various levels of charge from full down to nearly empty (it's a rechargeable battery). Everything you said is true, but all four conditions are exactly the same between the model in the video and the model I used. Thank you. I did test the motors by doing just that. Each will correctly turn whatever number of rotations I program, so I know it's not them.

Unfortunately, it is the first question I want the answer to. Why does similar programming result in different results? I'm beginning to think that Lego did not attempt to match the programming to the video after all.

Hi, I'm hoping someone here can help me solve this riddle. Going through the Robot Educator tutorials, I've programmed my Driving Base robot to do a full circle turn. I have duplicated the program exactly as seen in the tutorial, but my robot does not go full circle. I've tried it with multiple different bases and multiple computers and the glitch (if it is one) is always there. The firmware was updated on every base I tried it on. Every computer I tried it on was running Mac OSX El Capitan. I made a little video to more clearly explain the problem. I hope someone here can help me clear this up. Thanks!

Hey Everybody, Just wanted to say hello. I'm a middle school teacher in Los Angeles, and I'm excited to be using Lego Robotics in the classroom. Troubleshooting problems with the Mindstorms kits is what brings me to this site. Now that I'm here, I've got to say it's a very impressive site. Thanks, Ray
