I’m pretty sure you might need to lower the gyro’s further down for a lowered center of gravity. That would definitely help stabilize the unit and help with turning, etc.

Wow

Thats pretty cool. I can’t see how they are making it turning it tho. It doesn’t seem to have Gryo stabilises?!?! Cheers for the food for thought.

I still think you should

I still think you should make one! And even smaller than theirs, as well as autonomous. That would be quite an accomplishment

Here are my 3 things to

Here are my 3 things to add:

- cobaltphoenix already pointed out to move the gyro’s as much down as possible

- the servo moving the gyro’s must be a strong one and metal gear -> better would be a DC motor with a worm gear to get the force/tension of the gyro not carried to the motor/servo

-  steering could be done by swinging only a weight to left or right, like the motorbike driver leaning out… (so, no need to move the gyro’s)

- lasercut/milled aluminum would be the best choice for the main wheel since it already brings in a certain weight for the stabilisation

Well, it’s four things now…hope you will start working soon

I don’t think this will work as shown…

The gyros will drift so you can’t just hook them both to a servo.

You will need to turn them continuously and probably at different rates (I assume your gyros spin in opposite directions, one clockwise and one counterclockwise) so you will need one servo for each gyro and the servos must be able to spin freely in any direction ( continuous rotation servos ). If you do go with continuous rotation servos you will probably want to remove the existing control board because you will want to have fine control over acceleration, not just speed. Also, getting power to the gyro motors may be tricky since wires will eventually get tangled up… unless you can somehow fix that with software, hmm…

In any case, this is a great idea and I can’t wait to see your robot running around

It is for the same reason everyone here makes robots.

(for robotboy)

It is for the same reason everyone here makes robots:
1.) proof of concept
2.) proof of their own ability (mechanically, electrically, and software)
3.) for fun!
4.) this would be the first I have seen

Haven´t got a clue…

…if it´ll work, but I think it is one of the coolest things I´ve seen here in a long time!

Congrats!
