Last night we had some help from someone experienced with robots. He suggested our batteries were malfunctioning. A lot of them do so when they are used too much, so we bought new ones. But it still didn't work! We tried playing around the our gearbox a little bit. And guess what? Somehow we had too many bearing flats. Which somehow served to give friction to the axle. So it took it out and it worked great! So we attached the new improved gearbox straight and use a chain for more stability.

WE WERE SO WRONG! The shooter was going good at first, but then suddenly it started to hate us.
It moved fine at first, but suddenly slowed down and stopped. We could have sworn it was friction-proof, it's pretty much the same as what happened before with our robot! We might just have to give up on shooting. HAPPY NEW YEAR! We are almost done with our robot. All we need to do is add a tramp for our ball shooter. Our collector works well, but the space between the shooter wheel and the ball collector is a little too small, so the ball could get stuck a little. So we decided to make a smaller one and odd layers. We'll do this tomorrow. The robot is really stable and is almost done! We're doing really good!
Today is the last robotics session of the year! We attached the shooter to the base. We don't know if it would work, but it looks like it would work well. But there's a little problem with our ball collector because of a lack of continuity. With the ball going in straight, With the ball going in imperfectly, it slows
it fits perfectly down and doesn't fit the conveyor belt. So far this we decided to odd some wheels to connect the chain. But because the chain was a little too close to our wheel, it caught a little. We would have to move it forward a little. We completed our gearbox today! The problem was with an imperfection in hole-matching. So we fixed this, and it works much better! We had tried the chain but that mechanism lost us some power, so we went with gears. It works AMAZING! And in order to stay within the height limit, we decided to put it in an angle like this.
We removed the friction from the gearbox, but the axle catches on something. We'd need to take another look at it and maybe just change the box to a chain mechanism so that we can move out a little more (this would reduce the complexity of our robot)
We started the gearbox today, and it has very good gear meshing (it feels solid). But it may be a little too solid; it has a little too much friction, and has some problems moving. We should work more on it next time. We also attached the conveyor belt, and it works great!
Today we worked on a new ball intake system, where we utilized a (probably original because we've never seen any other robot do this) 'technique' to structurally enhance the robot. The first one we used was to use spacers and axle lockers to keep our axle form falling out of our motor clutch. Using spacers, we managed to put axle lockers directly in front of the motor and use spacers to even it out. We also created a suitable conveyor belt which we would attach tomorrow. This new robot has lots of promise!
Today, everything was pulled out of our base. Using I-unit-long steel bars (bendable) to make a rail for the balls, we managed to reduce as much weight as possible from our robot. This would help any potential elevation - seekers a lot.
Today we tried using a chain with the gearbox to give our wheels some more space, and it JUST DOESN"T WORK! It just has too much friction, not enough hearing flats and is just outright bad!
We will need to take EVERYTHING apart and redo it real fast! |
