How do you make a robot that kids can build?

Answer 1

it really depends on the kind u wanna build. Ive built battle bots and i can give u basics, but most of this u have to nswer on ur own.

if u just want like a car based thingy- go buy the parts. you can buy kits or bases for car bots then go build it and customize.

if u want a tank type robot, i recommend starting from scratch. Ive done this before, and its really fun. all you need is to know where to buy parts. i suggest a local hobby shop for ADVICE!! and buy ur parts online. robotmarketplace.com is a good place to start. good for all robotic needs

after this for like standing robots and junk, i don't know. below is a basic pats list for any robot.

MOTORS- these come in many shapes and sizes. first think of a motor. you thought of like the little things you get from inside toy cars and stuff. sure you can buy that, but theres more. I have bought motors from robotmarketplace that are about the same size, yet if you take two pairs of pliers and try stopping them, you cant. also Mae sure you know what size ur buying. theres antweight class (the size you find in toys) then theres beetle class (the size youd find in one of those cars kids ride around in) then you get into some crazy ones that probly wouldn't be much use. also go for brushed motors. unless ur a serious fanatic, brushed motors are a lot cheaper and have very little difference in ability. motors can cost anywhere from 10 to 100 dollars

Transmitter and Reciever Radio Controls- these can get costly. bout 100 bucks for a cheap set. however, its not just pick randomly here. 2.4 Ghz controlers are the best, if ur not around lots of cellphones. if ur near too many cellphones, the 2.4Ghz controler is messed up by the bluetooth. also becareful not to infringe any of the FCC regulations (don't use airplane only signals for a ground robot or vice versa)

structural materials- gotta make the body out of something bub.

ESC- electronic speed control- takes the power from the battery/receiver and varies voltage to increase and decrease speed based on the signlas ffrom the receiver. cn vary in price. tank ones can cost ~ 60; nontank single motor ESC cost less.

servos- not generally used for tank drives, these are special motors that are used for steering. vary in price, usually cheap~10-20

batteries- this can get very long, so look for the question "Which is better a cell-battery or a Litium Ion battery". there i explained all the types of batteries and their differences

Frankly this is a BIG undertaking but a lot of fun. it can be a headache, so get ready for it and make sure u want to do it, or else you could waste TONS of cash.

THIS IS NOT A CHEAP UNDERTAKING
