What could I use for muscles; is there a material that quickly contracts when electricity is passed through it?
I don’t plan on building a robot, but by askin these kind of questions, I can learn things about this kind of thing, and hopefully, be able to one day…
first of all you have to decide what you want it to do –
from there you can figure out the rest
I doubt any robot hobbyist uses the exotic materials needed for artificial muscles – usually it’s electric motors and gears or perhaps hydraulics or pneumatics that are used to make the parts of a robot move
until you figure out what you want it to do – I can’t really give you much advice –
say for instance you want to build a ‘battlebot’ – you know you need propulsion – a way to make it move – a weapon of some sort – and the ability to remotely control it all – it’s pretty easy for your mind to take it from there – you need wheels and steering and a motor and . . .
now say you want to build a robot that will do a spot weld for you – ok it probably won’t need to move
see my point you need to know what it’s going to do
