Step 7: Testing

The robot is now completed and it is time to test it.
Put 4 batteries into the battery holders and turn on the switch.
Try to change the position of the sensor to make the robot works better.
If the robot works inverted swap the red and blue wires on the sensor or on the battery holders.

It seems to me that the center of gravity is high which causes the robot to have to react faster than it is capable of due to the circuitry delays, inefficiency of the wheels to move as quickly as needed.

I have two Segways (a blast, by the way) and they stand up on their own. It's fun to watch them "dance"..

I literally had to go to the factory in NH to take a class on how to ride these models. Yes, long time ago.

What they suggested this: to stabilize my units when first riding it, add some weights to the saddle bags on either side. It not only helped me when learning, it helped the Segway stay upright without excess movement

So what I'll seggest (lol) to you is this: get the center of gravity lower by moving the batteries down or adding weight to the bottom of the plastic. That should allow the bot to stay upright without falling over.

It is the sensor of the robot that changes the direction of the robot's motor when the robot tilts.

I'm going to make a segway scooter for myself !!
Very creative!! I am going to build my own version of this robot!!
