Wicket the Ewok-bot is your furry little guide to the Endor moon, and a loyal friend in battle. Using a remote control, you can navigate Wicket through the forest. His staff will light up when someone is near. And he's a chatty companion, helping Princess Leia avoid trouble. When it comes to defending his home, he sends out the Ewok-battle cry on his bugle. As a mom-and-daughter team, we constructed Wicket from an old stuffed bear, some fabric materials, pipe cleaners, a glue-gun, and some hand-moldable plastic to shape the horn-bugle. We used to Droid Investor's Kit chassis as for the internal frame. The remote control used the 5-channel wireless transmitter talking to the 5-channel wireless receiver. Each output controlled a different set of functions on the droid itself:
--one button triggered both the DC-motor controlled back wheels, to drive the bot forward;
--a dial-dimmer turned the front wheel (controlled by the servo motor);
--another button triggers both the sound and the latch-connected proximity sensor which then controls the long LED light that was wrapped around a pipe cleaner to make an illuminated staff. (We decided to use the latch so that we could get a longer lasting response on the proximity sensor.)
We had a lot of fun going on the internet to find Ewok sound clips. We downloaded 3 clips to the micro SD card for the MP3 player:
--the Ewok battle cry;
--the converging and collective hooting of the Ewok tribe; and
--Wicket's first meet up with Leia in the forest.
We transferred the micro SD card to the MP3 player bit hooked up to the speaker. Each time the button on the remote was pressed, we heard one of the sound clips. Annalisa was especially excited to drive Wicket while he was making sounds.
We learned a lot about how some of the more advanced bits in our collection worked (the 5-channel wireless receiver and transmitter, the MP3 player, the latch, the motors, and the proximity sensor).
And we also now have a new cuddly interactive toy--even our 2yr old loves to play with him!
