Week 6 Updates

In class today, Mia painted the exposed wood black to match the fabric.

Stuti and Casey determined that we had been using the wrong motor (the DC) and should have been using servo motors instead. They checked them out from the co-op office (Tower Hobbies System 3000, STD TS-53). These motors will allow the arms to move back and forth at a slower pace than the DC motors were allowing. With the servo motors, the arms can be coded to move from 0 degrees (down at the bear's sides) to 90 degrees (straight out in front of the bear). Stuti found code online that works well with the chopsticks for inside the bear.

The DC motors can be used most likely for the smaller bears in the back of the box. With the contraption in mind (see below picture - the center drawing), the DC motors spinning continuously will be the best option to make the small bears sway back and forth constantly.

The center picture represents one of the two background bears in the box. The bottom circle will be attached to a DC motor and then spin. The stick will be fixed to the disc and the other end to the bear. When the motor spins, the stick will move the bear in a somewhat figure-8 motion.

Stuti researched and set up the PIR Sensor to move the bear's arms when the sensor is activated. See the pictures below to see the set-up of the breadboard and the Arduino Uno.
