Let the testing begin!

Today the design team had a wet run with version 0.1 and the polar bear puppet. It was awesome to see the polar bear move how we inputted in the application. There are some bugs, however, with the synchronization of the servo with the audio files. At the moment there seems to be problems with where the servo should start as the minimum position, which would be the mouth being closed entirely and the maximum position, which would be the mouth totally open. Some of the audio voice files had the mouth starting a little open and we couldn't seem to do anything to make it start in a closed position. Aside from that everything else seemed to work with minor difficulties. As a team we logged in some issues on Google Code which were a little tricky. I think we got a good start and i think as a team we will be able to find all the major bugs...the question will be if the implementation team will have enough time to squash them all! I am optimistic with the outcome and i think we will have something that will perform as good or better than what is out there.

Aside from the testing, I have taken on the task of making our drab and ugly GUI into something that is more pretty and fun. I discussed with some members of the implementation team last thursday about what we as design team could do and they brought up that we could actually design the pieces to the GUI. I have always dabbled in graphic design so i said i would be able to facilitate that for them. Last weekend i was able to get the zoom in and out icons completed and will be working on creating the rest in the weeks to come. For those interested I have posted below the zoom in/out icons...

Version 0.1

This week we had Version 0.1 showcased by the implementation team on Monday. It was very nice to actually see components put together to form some sort of application. My project gantt chart i made awhile back had us scheduled to receive 0.5 or close to 1.0 so 0.1 is far from that. However, it shows a lot of promise and i hope after our thursday team meeting we will have regrouped and ready to git'r done!

I had organized the design team to be ready for testing as soon as 0.1 came out but unfortunately with all the known bugs it seems pointless to test something that the implementation already knows is broken...nevertheless I have told everyone on design team to take a look at 0.1 and tinker around with it so that we are all acquainted with it when thursday comes. All three teams need to reconnect and refocus so that we can get this all done in the given time. I am confident that we will succeed.

Today I played around with 0.1 and i think it is great for what state it is at. It is by far from looking pretty but that is expected. I am skillful in the ways of graphic design and have made prototype screens for the app awhile back to communicate my ideas. I think that i may be able to use what i have created to make the GUI look less like windows crap and more "kiddish". We will see what we decide on collectively when it comes to that. There were mentions of hiring a graphic designer but i am not sure where that has gone.

I also spent tonight setting up the Google Code site for puppetronix. I took the 0.1 file and uploaded it to the Downloads section. Now everyone can download it without the google group trying to display the rar file in hex! I also started to enter some issues that i have found thus far with 0.1. Since some areas were not completed i tried to focus on things that were more solidified. Vertical lines down the timelines so that you can follow what time unit the blocks are occupying was something i saw missing. Some prompts were missing like allowing users to create characters with no names. I also took the To Do list and placed it as a wiki page on the Google Code site. Since the issues will be housed on the Google Code site i thought anything to do with improvements to the app should be hosted and discussed on Google Code and not on Google Group.

I don't think we have finalized our logo for Puppetronix so since i have posted images on most of my posts i will leave you with this logo concept i created for this project...

Turtle Turtle

Today we had a design meeting to basically get a sit rep (situation report) on everyone's tasks and to coordinate the coming weeks. Some design team members will be away for certain periods of time in July, which will make it more demanding on everyone. It seems like through the grapevine that the implementation team will have something for us to test on monday. We have pro-actively set up a bug reporting system using Google Code. Basically it is a free service where you can share code, report bugs, etc by inviting collaborators using their gmail accounts. This will make it easy for all the teams to coordinate and cooperate in the coming weeks when it comes to fixing the application for children consumption.

I had a request from Ali (Hardware Lead) to help in the design of the turtle. I had a cool idea of making the turtles head pop in and out of his shell. I had a design awhile back but never transferred it onto paper or bits. Ali wanted to use three servos for the turtle to have his mouth open, neck swivel and go up or down. That design would require 3 servos and it would be quite interesting but for the turtle i think we should really look into making the head go into the shell since the hand puppet is designed to make it possible. It didn't take me long to design something into 3-dimensions for the hardware team to use. Google Sketchup has been a great 3d application that i have already used for the Polar Bear puppet. It was a great tool to show the whole team and have everyone visualize what we were creating instead of scribbles on paper.

I hope hardware will take my design and create a turtle that will be able to pop his head in and out of his shell.

For those interested below are some screenshots of the simple design of having a neck that pops in and out. The principle behind the design is using a lever action to make the neck pop in and out. With a lever that is pivoting with a shorter and longer end it provides the ability for the servo on the shorter end be able to pivot the levers longer end, which in turn creates more travel for the neck. If the servo was connected to the longer side of the lever than less travel would be created for the neck. Therefore, it is essential to get the right ratio for the lever so that we have enough travel to get the head out and in the shell.

Polar Bear shall stand...back to hardware!

Nothing new to report on the design front. Everyone is working on their tasks to prep for what will hopefully soon be an application that we can test! We finalized the last portion of the design doc around a week ago and that was to finalize the audio functionality of the application. Allowing users to import audio and modify accordingly, if all goes well with implementation we may have the ability for users to record within the application and have them dynamically synch to servos. This would allow users to synch several servos to an audio clip and have them react to it.

I have reached out to the Hardware team to see if they are on track and need any assistance from the design team. I talked to Ali earlier today and was able to help him out in designing and creating the stand that the Polar Bear robot will stand on so it can be tested once the app is ready. The original design for the stand was not as sturdy and low profile as I would like it so we were able to design a low profile (only 2 inch) stand that allowed for the polar bear to stand on all fours and have his head positioned right. It is quite a simple design and could be used for other robots once hardware have completed them.

It was nice to see the polar bear once again and have it stand by itself and not lying around like a dead polar bear. His movements are quite realistic and should look good once we can input some commands to the servos via our application.

I would like hardware, for that added touch, get some fabric and drape the fabric on and around the stand. It would hide the stand very well and also give that professional look to the entire thing!

Cheers,
