Oogway

Oogway, the wise turtle, has a light sensor on the top of his shell. When someone pets him, a shadow is cast over the light sensor, thus triggering the PicoBlocks program to start. Oogway's head extends out of his shell through the use of the Back-and-Forth motion module and a PicoCricket. After a few moments of contemplation, Oogway's eyes flash a random color for several seconds. Then the motor turns on again in the reverse direction, causing Oogway to retract his head back into his shell.

The Dragon Catapult

the catapult motion module

We used the Catapult motion module and a PicoCricket. A touch sensor is plugged into the PicoCricket so that when someone presses the touch sensor, the motor turns on and catapults an object (the Dragon Scroll).

Po

Po sits on top of a four-wheeled car (with a gear ratio of 9:1) powered by two motors. The motors are connected to a PicoCricket on top of the car. Also connected to the PicoCricket are a sound sensor and a light sensor. Our program begins with an auto-thresholding by the sound sensor to detect and record the background noise level. After that, depending on the volume detected by the sound sensor when compared to the background noise level, Po goes straight, turns right, or turns left. The light sensor is attached to the end of Po's triangular apparatus. There is a magnet at the end, and when the it picks up the magnetic Dragon Scroll, light sensor is blocked and stops Po from running.

Tai Lung

Like Po, Tai Lung also sits on top of a four-wheeled, 9:1 gear reduction car with two motors and a PicoCricket. He has two light sensors, one on each shoulder. Our program starts with the light sensor doing auto-thresholding to detect and record the lighting condition of the environment. When the left sensor detects more light, the left motor turns off while the right motor is on, causing Tai Lung to turn left. When the right sensor detects more light, the right motor turns off and the left motor is on, so Tai Lung turns right. When neither sensor detects more light than the lighting condition of the room, Tai Lung stops moving altogether.
