@sigma When I was in high school I was part of the robotics team. That little motor is a non vex part (it comes from the FIRST Robotics Competition kit). The motor is actually from a Frisher Price kids car, ya know those little plastic ones every kid seems to have at some point. That motor is bolted to the wheel with only one gear reduction to give it just enough torque to launch the ball. The motor itself is wired into a Victor 883 speed controller and attached to a vex remote control battery.
@sigmazombie No, sadly. That robot was the only vex bot I have build. I was using one of the school's kits to create a demo robot for the teacher in charge of the robotics program. I have my own kit and I have had many ideas but I have just never gotten around to building them.
@mambroz wow u should challenge urself like maybe make a robot to pick things up or climb stairs i recently went tot he vex robotics camp and i got to build a robot with 2 other people on my team and we won first place the challenge was to get simply into a cup that was elevated we won cause we had the fastest ability to grab the ball
@sigmazombie very cool. Yeah I need to get back into the whole robot thing. I have more time now that I am done with school. The only down side to vex is that radio shack no longer sells the kits and extra bits. I always felt the motors were a little under powered as well. I guess you cant ask for much out of those servos though.
@mambroz welo i do think vex kits like those are made for practicing and learning the basics besides if u made a car with a super fast motor it would be to fast it would probly take out some screws everytime u use it and flip wen u try to drive it but maybe u dont mean as fast as the motor you were using in this robot
@sigma Yeah I most certainly do not think that the vex motors need the power of the fisher price motor I used for that robot. If you ever try to build a robot with a tank tread drive system (opposed to wheels) and with the weight of that bot it's ungodly slow. I think what vex really needs are some motors that have maybe twice the power of the standard ones in the kit to be used as drive motors. That being said if you build a small, light robot those motor work just fine and give you good speed.
@mambroz that was on of our most frequent problems the competition was to get balls into elevated cups and we made an arm with a turbine to suck in the wheels and the arm was so heavy it cept stripping the motor and we moved at like 1 foot per 3 seconds
@sigmazombie Yeah, the teacher that ran the robotics team at the school had a vex class and that was one of his most frequent problems as well. The clutches on those motors strip out so easy. That was one problem we never had on the robots. But like you said vex is more a learning and introductory tool. The fact that given some knowledge, a search engine, and some free time people can create some crazy robots is just a bonus. Like that bot it wasn't pretty but it shot racket balls like 13 feet.
@mambroz ya and another good thing about vex is it is easily repaired my team had to take the whole base apart and put it back together in one hour and we did it and we stripped a motor 30 minutes befor the competition and we were able to change it
@sigmazombie yeah that is true. they do come apart nice. Sometimes I feel that the vex parts are a little flimsy but with the right construction they are fine.
@sigmazombie Yeah I will admit I did bend some pieces too. The nice thing about being able to bend the pieces is that you can create complex pieces without a lot of machine work. On the other hand I still contend that the inherent flimsiness that allows you to do that also forces you to over engineer things that need to be really rigid. Although they do have angle and c channel pieces that give better structural integrity. Especially if you bolt two c channels back to back to create and I beam.
@sigmazombie the angles are pieces that have a right angle bend in them, like an L shape and the C channels are pieces that make a squared off C shape.
why are they all the same? i know this was 4 years ago but still

@sigmazombie the three videos are just different angles of the same robot. The hope was to give people a glimpse of how it works.

@mambroz using your rescources i see is there any other robots you have include the turbo motor in?

@mambroz well they are very i think every robot at the competition purposely bent a piece so theyre robot would be better even my team did
