Need help on informations (THE ARM OF THE ROBOT)

[Achan]

hi! need a bit of information to help me get into my schools robotics team. Wondering if someone could send me some info on how the robot moves (eg. how arm of robot is controlled)..if someone could do that it will be great!

Thanks a bundle!,

uhh.. it matters on the robot you are talking about.
well the drive system( how the robot moves ex)wheels. treads.))are normally with motors. mostly the drills, chips, fp motors.
the arm(s).... well, there's endless ways of makeing an arm move. motor driven and pneumatic cylinders seem to be the most popular. of course, springs, gravity, and many other forces can be used too. and how they are controlled?
motors would normally be controlled to speed controllers aka victors.

ehh. i need to do hw. sumone take on from here

well, our robot arm had all its weight on a 1" aluminium bar, so if the bar would break, the arm would come completly off. That was our first time in robotics compitition, so we didnt exactly plan everything out that well..so i thought we could get some ideas of what a better version of an arm would look like..

how do you know that you would exactly need an arm as a mechanism for 2005 FIRST season... it always depends on the game... or atleast i think it does... there was another thread started by your own team member about the same topic... i have posted some basic information. please check those out... i hope that helps you out...

if you need know about robots to join the robot team, i feel bad for you.

I always thought FIRST was about anyone being able to learn and get inspired to pursue a career in technology... Aren't these teams here to teach all students about robotics and engineering, not just the ones who already know about it? That bugs me.

oh no! dont worry, we dont HAVE to know anything bout robots, but since we have like 100 people who want to join, and only like 40 can make the team, i feel that knowing a BIt of information wont hurt!

Magic smoke makes the motors work which provide motive force for various objects on the robot. Sometimes pneumatics too.

I would suggest, get in touch with one of the mentors from Team HOT. they are great. i am sure they would be more than happy to help you out with that...
