Robotics Final Summative

Final Robotics Summative

Introduction

For my robotics I decided to make a lego claw machine for my final summative and it wasn’t that good of a project. This is my final robotics summative. [1]

Collaborative Process

For my collaborative process, I didn’t work with anyone and was a solo project, and I feel like if I had someone else work with me, I could’ve had a better chance of finishing this project because the planning was easy but the I had to build a lot which took up a lot of my time. So basically I don’t have anything to say for my collaborative process as I worked by myself.

Idea Development Process

In the beginning I was hoping to make a robotic hand that could hold anything but then I realized that was too difficult to make and then I decided to make a robotic claw like the ones you’d find from disneyland but then I realized that was quite easy so I decided to make it a little bit more challenging by making a lego claw machine. In the beginning I wanted to challenge myself and I decided to make a whole claw machine with cardboard too and a coin slot which you can use to use the machine, and a joystick but in the end all I ended up making was making the claw be able to move up down left right and have claw life up and down and I couldn’t even input the program in.

Technical Process

I first tried making my claw machine, I made it completely out of lego [1], then I realized that the claws and the motors couldn’t withstand the weight so I decided to make a part of it out of matrix and I needed some of the lego for the motor. Then I made the claw rope. I first tried a normal rope and it was hard to put all the string to on the lego piece and would slip off and I started making the rope with lego and it was quite successful. I basically made all the motors [2] and all I needed was the base. I started building the base to hold it up. I collected all the materials to build it and to sustain it and the next day they were all gone. So I went on to just use the straight metal parts instead and it could not sustain itself. Until this day, I always went on break and lunch to work on my project but I guess I got fed up and gave up with the project. So when I came back the next few days, the lego was broken because that was a weak point [3] and it was holding almost all of the structure falling apart. Then I was sort of stuck. There were no materials that I could use and I got these things in the photo and I tied them with a string onto the claw machine [4]. Once I was done with that I had 3 days left and I had to make sure that I finished the project I had to finish programming, wiring, programming for the matrix motors and I think it was just too much and I could complete it, but I just didn’t have enough time to make it work. The motors here were very wobbly and could’ve fallen very easily and I needed to improve and I sort of gave up and I’m currently writing this blog post.

Concerns or Celebrations

This project was almost full of concerns, that I made the whole thing out of lego and I had to make it all over again with matrix. Which took quite a bit of my time, my motor which had the lego claw machine is very fragile and still is to end of the day. I also lost all my materials when I put it in my lockers, I also had almost no materials. New materials came though on the day when I stopped working. The whole structure was very fragile. I didn’t have enough time too.

Look at images above.

Knowledge I Can Transfer

I honestly think that I was just unlucky with the materials part, but I think that I should prevent that from happening if I get the materials first and keep it hidden or I should’ve locked my locker. But the key was broken so I don’t think there was any point to it. Again I think that I should’ve been more prepared to this and planned more well and thought more about the errors that could’ve happened during this project.

Final Project

This was how my project looked like in the end of the project.

SPOILERS For: Heaven is for Real

Kid Goes to Heaven

Screen Shot 2015-12-07 at 11.08.06 PM

For my blog post, I wrote about the book Kid Goes to Heaven written by Todd Burpo which is a autobiography. I wrote a newspaper article explaining the story and talking about what happens and gave a newspaper feeling and from a third person perspective. I also included in little subplots such as “Little Girl Holds Spider” This is where the Colton’s sister takes on a big challenge and was able to hold a big spider in her hand. The other part is the fun fact which explains the plot too. Then there are just random fake stories to put in the newspaper as I named in as “The Random” So that I could fill up the space. I also included quotes from the story and gave more information on how to find the topic. I forgot to put where to find the quotes in so here it is . So this was basically my multimedia post which is the story in a newspaper format.

Robotics Pulley Reflections

For my collaborative process, I worked with my partner Erik Kang, and it wasn’t the best collaboration we could’ve shown. While we did this, we gave each other roles that we should do, such as build things. For example, I would build the wheels, and Eric would work on the strucutre, but the end was not so great when we planned things. When I would say please work on this part during break, or we’re not going to get it finished, I would hope he finished the work so I could continue mine, but Eric wouldn’t show up at those times, he also in the end, we decided roles, and he would work on the coding for the automated machine, and I asked him to work at home for it but he took a week and a half to finish it and it was quite frustrating, but when we were both building, we were quite effective at building. Idea Development Process In the beginning, we thought of making 3 short empty boxes and place the last one at the edge, and the pullies were set out like this. But then when we actually looked at our resources we realised that we didn’t have enough resources and we switched our idea to this. Then we put it as planned and did a stupid mistake where we realised it would be extremely difficult to put the string through so we had to make it into a straight line. We also realised that the string was sliding off, so we got rid of the tires so that the string wouldn’t slide off. Maybe our design was bad, but the string was very difficult to pull and was hard to do when we tried pulling on the strings and they overlapped each other creating friction so I removed 2 wheels so that there would be less strings overlapping, next we also realised that the line was bending when pulling on the rope and we decided to put some support on the lines by putting legos on the bottom of the lines so it wouldn’t bend as much. Then when we pulled the line it actually worked. So when we built our motor, we removed the top wheel and replaced it with that and how it worked was the motor would pull the string roll it up around a plastic, we realised that plastic also bent, so we put a little lego on the plastic so that didn’t bend either. I was concerned that it wouldn’t work because we didn’t plan very well, I was also scared if we could even get the bottle to go up even if the plastic didn’t bend. Next time I think I should plan out our project more carefully, as we just went with what we got and didn’t plan too much.
