Would you please to provide the new p file version because this one is the old version that can not run on recent matlab release. Thanks in advance
when I run your simulation I am getting the following error. Can you tell where it might be wrong 'nxt_ballbot_sfun.bat' is not recognized as an internal or external command,
operable program or batch file
Works almost perfect - I've been able to create and test one in our university's robotics lab - still need some tuning, mostly because of gyro sensor offsets I guess. Anyway very spectacular one ;-).
Thank you for sharing!
