Robotic pet (low budget)? Answered

Hiyas I am longing loads for pet of my own since my bunny died. but i am not allowed another pet. does anybody have any ideas of how to make a *loving* pet???? 
p.s this is my first ever comment on instructables!!!!!
pp.s needs to be low budget (eg. under $100)


Several decades ago, some folks were building "pet circuits" known as dreeps. The ones I heard about were completely analog, built into a pocket-sized case,and were designed to be sensitive to light, heat, sound, and maybe a few other things. Depending on these inputs, they would generate a "dreep" sound -- more or less frequently, louder or softer, different overtones, whatever. The art was to design one whose behavior was fairly intuitive -- so it seemed to like being handled, "went to sleep" under conditions when its sound would be annoying, and so on... but also retained some element of surprise.

These days, I think I'd build one around a microcontroller chip, just because I'm better at digital than analog, and for me a digital dreep would make experimenting with different and complex behaviors a bit easier.

I don't know whether that qualifies as a "robot" -- but if you design the parameters properly you can make it appear to enjoy being held and petted, and that comes as close to simulating affection as you're likely to get at that budget.

Or you could just buy a tamagotchi, though I find that much less interesting.

Or you could talk to your family about _why_ you aren't allowed another pet, and find out what it would take to change their minds...

Buy a robotic pet from internet under $100

Thinking about designing it on a pika

Pets don't love you, it's a figment of your imagination.
Pets are dependent though, so you need to build in that - e.g. Tamagotchi-like


My cats have got me pretty well figmented. (I don't think they "love" me, but they certainly seem to like having me around, and that's mutual.)

Hmm theres another question about that thanks

You should be able to build with a little effort a working running robot for about $14 - over the new week or 2 I will post a step by step instructable to show how. - Watch this space.

In the mean time there are already several build a robot instructables here if you search.

Please give us some idea of you age, experience & will your parents be able to help. (I may be making an assumption about age here!)

well i am 14 have mild experience but my dad has lots of lots and he will be able to help

Good you shouldn't have any problems getting parts then & someone to help with the easy bits! I will get to this this week.

Thanks soooo much everyone a GIGANTIC help ,sooo many really nice people on instructables
