Robot arm trouble
Mcrich113:
Hey guys!
Listen, I'm fairly new to robotics and need help. Iwant to make a robot that is like an RC car and has a robot arm (got the idea from the robot arm tutorial ;D .Sounds chalenging right?And it is, I am trying to make the arm like a humans, 2 servos for shoulder joint(one to move it around and another to help it dive foward), one for the elbow joint, 2 more for the claw, and 4 for the wheels ,it seems as though i got it right, WRONG :'( . I have lots problems. First off, from what I have descipted,do i have enough servos :-\ , second, i want the robot to turn, how do I do that, also, what matreial do i use so the arm will move right(Tell me something better than cardboard but not as heavy as wood, finally , and most important, WHERE DO I GET GOOD ROBOT PARTS AND RC THINGS CHEAP ??? ?.
thanks Mcrich113
P.S. oh and this place rocks ;D !

welcome to the forum
first we will start with the R/C part
I'm thinking two modified servos and a caster wheel , giving the vehicle differential drive
then an r/c receiver going to the microcontroller which will translate the signal to movement
as for the arm
do you want something like
why do you need so much servos???? You realize that you can't possibly control all these servos yourself on a remote
also a lot of the servos you mentioned are overkill. You need one servo to bend the arm , one to tilt the gripper, and one to actuate the gripper. Thats it

hi guys
Thanks for the reply airman00! Now on to buisness, thanks for the sevos thing, i bet it will help, as for the microcontroler, slight problem, not that I argue with the idea, but i don't have the time ,money, and exprience to do it! I know its written in the 50 dollar robot tutorial, but I just cant writ the program(i would have to write that myslef right?) also, i cant get parts. also I was hoping someone could help me here, I want to know if there is a good robot club in torrance,cailfornia.
Thanks! Mcrich113 ;D
airman00:
well Mcrich113 , your situation is pretty bad
you want to build something like this
but you have no parts, no money, no experience , and not time
california has a lot of robot clubs. You'll need to search around
Do you have a budget at all?
Mcrich113:
Okay, look I have a budget of $25 (I have lots more but my bother won't let me use it),Problem? WHERE DO I GET PARTS?!?!?I live in los Angles in the west section of torance , cailfornia , i need to get parts from some place that is easy to get to, and if u really think i need a microcontroler than okay, just tell me what types of parts I need and I'll get it
P.S. Ill see if I can get more okay?
