I made this the other day for my 7 year old. She's been into ZhuZhu pets since they came out and as with any toy the more you love them...the more likely they are to end up a little worn out. That was the case with this little guy. Being a tinkerer, I was going to take the dead ZhuZhu apart and harvest the motor, gears, etc for later projects.
Once it was totally apart, I was inspired by the shape and look of the circuit board and the over all style of the parts I had left. SO...I went to my parts bin, pulled out some scrap wire, a salvaged white LED, an old on/off switch (from a dead power supply), and a few old wheels from other former toys. After about an hour of soldering the parts together and modding the case just a bit, I mounted everything backing in place. and this little creature was born.
It's not technically a robot, but instead just a cool little toy that roles around the house and from time to time bugs the cat. The upgraded wheels offer a bit more clearance on the floor and there by has also increased it's speed, making it a bit more fun to chase.
My daughter loved the fact that I salvaged her ZhuZhu to create this and as her others pass on, we plan on making more. She named this one "Roller-coaster", but she normally just calls him "Little Guy".
