Jim Posted July 1, 2014 Posted July 1, 2014 Laurens Valk has posted an elaborate tutorial on building your own self-balancing robot on his blog. Check out the full article. Quote
Holodoc Posted July 1, 2014 Posted July 1, 2014 This is sooo cool! I can't wait to open my EV3 ... on Christmas. I definitely will have to check this out then But is it possible to build this with a pure EV3? The movie states you have to have a gyro sensor (where to buy?) or an Education Core Set. Quote
Jim Posted July 1, 2014 Author Posted July 1, 2014 You will indeed need a gyro sensor. Bricklink will probably have some sellers. Quote
Philo Posted July 1, 2014 Posted July 1, 2014 (edited) You can also get LEGO gyro from shop@home and Laurens' balancing robot can also use Hitechnic gyro. Edited July 1, 2014 by Philo Quote
legolijntje Posted July 1, 2014 Posted July 1, 2014 Well, this (older) model is a segway type model that doesn't use a gyro. I don't know if the performence is as good as with a gyro, but it works. But, it would be nice to buy a gyro anyway, because gyro sensors are just fun Not only for Lego. Quote
Tommy Styrvoky Posted July 2, 2014 Posted July 2, 2014 cool idea , the gyro sensor can be purchased from legoeducation too https://shop.education.lego.com/legoed/education/LEGO+MINDSTORMS+Education+EV3/EV3+Gyro+Sensor/45505&isSimpleSearch=false Quote
anton1678 Posted July 2, 2014 Posted July 2, 2014 I tried to make one with an ultrasonic sensor with nxt... But I suck at programming the thing, I messed it up in that part Quote
Doc_Brown Posted July 2, 2014 Posted July 2, 2014 (edited) I have a hitechnic one, do you think I could adapt this to NXT2.0? I built a balancing robot before but could not make it controllable. :( Thanks for sharing Jim! Edited July 2, 2014 by Doc_Brown Quote

I don't thnk it's possible to do that with NXT US-sensor: response time is too high (12ms) and resolution too low (1cm) to allow this.

Holodoc Posted July 2, 2014 Posted July 2, 2014 I just ordered the gyro sensor. (together with the free CS figure and the Chima giveaway I couldn't resist.) Quote
