I'm then measuring the angle of the robot manually, and when I apply 45 degrees from equilibrium, the integrated angle is about 15-20 degrees.
Hi guys, I've been following this thread for a while. Any news on how to add remote control, with say PC USB Gamepad and Xbee. That would add icing to the cake.//uncle_tom
10K hits and still no commertial product, in the last 12 months of work I have learned its still very difficult to get a stable balance. but what then, mapping, prediction and recognition. we have had 4-wheeled non balancing robots for years but only hoovers .Mapping is the next hurdle.
I have problems with the signs of the Acc axes. For instance, I have for 0degrees (bot standing upright): AccX=0, AccZ=63for +90 degrees (bot tilted towards front): AccX=63, AccZ=130for -90 degrees (bot tilted towards back): AccX=-67, AccZ=125for 180 degrees (bot upside down): AccX=0, AccZ=193
sensorZero[ACC_Z] -= 100; // Sensor: horizontal, upward
Announcement:The complete Balancing robot tutorial is now hosted on Patrik's blogIt will be updated on a regular basis.
I have used the xBees for a wireless serial link and also for wireless code uploading.
Has anyone tried this project with stepper motors? Would this make the task easier or more complicated?
How are you Kas?I just wanted to thank you again for your post *balancing robot for dummies* it helped me a lot, and want you to be the first one to see my improvements:http://www.youtube.com/watch?v=oM-j-L3Jg7Qthis is using a complementary filter and PID with a sparkfun IMU... going to use encoders soon and then RC control.I was wondering, is this any good? how much better can I get without using encoders? why is it drifting like that when I push it harder? Tunning more P or D doesn't help!any comments about it would be greatly appreciated thank again!Nahua
