: We are having great difficulty developing a program that uses gyrochip to automatically balance the robot. Also, has any team developed a robot that can balance automatically without relying on the gyrochip. Any help and suggestions will be greatly appreciated.
: Thank you in advance.

We haven't quite figured out the gyro yet, but we are getting there. As for a balancing act, with out actively using the gyro, we are using one now that uses the gyro as a trigger for a programmed response only. That is, at the slightest detection of a tip, the robot automatically drives backwards and then forwards and then stops. It is not very sophisticated, but it works like 95% of the time. Two goals, one goal, uneven ammount of balls doesn't seem to affect it, but we have only been testing it for three days. The big drawback to this balancing strategy is that if it doesn't work on the first try, the robot has to try again. And if it continues to miss the magic balancing point, there is not much you can do, unless you can use the operator interface inputs to adjust the drive distances or speeds on the fly (Hint Hint: it is working on the Techno Tick).

As for the "Trade Secrets", this is not a very sophisticated balanceing strategy. If you haven't gotten this to work in a week, we will post the code for all to see.

The Techno Ticks are on the MOVE!
