Test Results, Yamabica Robot Contest

I received my test results last week. I still remember very vividly when I did my EN433: Mechatronics Applications final examination at Uni. of the South Pacific in November 2004. I had thought at that time that it would be one of my last written exams....of course later from 2005 to 2007, I studied for the Diploma in Tertiary Teaching and had examinations in that too but I never considered those to be "real" exams. And yes, there were also examinations at MSc level but they were of a different genre. I had thought that I had passed that phase of my student life where I would study late nights for exams but now here in Japan, I am still having exams.

For Grammer Part 1, I scored 42/44; Grammar Part 2 = 98.5/113; Listening = 37/44 and for Writing, I was graded as as A. Well numerically, these scores look ok but I think a fundamental shortfall of the current course is that I`m not praticing my Japanese language outside of classes.

On Saturday May 31st, Roboken held it`s 2008 Robot Contest and I witnessed first hand some of the technologies that I would be working with later this year.

Now, if you have scrutinised this blog well enough and have been a good critic of it, you would have noticed that the title of the blog totally contradicts its content: I have so far not mentioned much about my PhD studies here but rather things and stuff I do.

Well the reason`s quite simple. I was overwhelmed by what I saw in my lab and so decided to do things one step at a time...and the first step was to concentrate on the Japanese language classes. When I first saw my lab, I thought: what am I, a student from Fiji - a developing country where there are "engineers" who don`t even have a first degree and yet still call themselves engineers, a country where a pothole in the road is repaired only to have it reappear as a much bigger pothole a month later, a country that has been independant for almost 40 yrs and even then can`t still provide a continuous supply of electricity for even 12 months without power outages (Don`t get me wrong....I do love my country), doing in the midst of some of the smartest people, in one of the most dynamic fields - robotics?????. Instead of a culture shock, a Technology-shock was what I experienced. Studying for a PhD was never going to be easy, I always knew that right from the beginning and yet I still chose to leap right into the Mecca of robotics. But hard work is something I`m used to...and that is what I`m here for right? So instead of writing about my lab before , I was all the time familiarising myself to it and now I can say that I have recovered my confidence to take up the greatest challenge of my life. Gambarimasu Aneesh!

Anyway, some details about my lab: The lab itself started in 1976(!) There are three professors and some 40 odd research members, most of them Masters students and a handful of doctoral students. Every year this time, a robot programming contest is held where the students get to choose their own research idea and then try and accomplish it. The event started at 10am and finished right at 10.30pm with a party.

Amongst my favourite was this demo...a robot that is able to identify a Coke bottle from some other bottles and retrieve it. Some other interesting robots: a robot that follows the shade casted by an umbrella. When a person walks with the umbrella, it follows the umbrella; and a soccer playing robot. Here are rest of the pics. Luckily I was strictly an observer but next year, I`ll also have to participate. If you have any (simple!) ideas on what to do, pls let me know!

Hirasuna Festival

My Kanji test was OK. I only made three minor mistakes so I was satisfied with my overall performance. But on Friday, we were given the schedule for next week and we found out that we have a MAJOR test coming up next week.

Well, thanks to the rain, our plan to go to Ushiku was again postponed, the 4th time in as many weeks.

After the test, on Friday night (May 23rd), I went to the Hirasuna Festival . If I haven`t mentioned it before, Hirasuna is one of the other dorms here at the University. My dorm is Ichinoya and the two are at the opposite ends of the University Campus. In comparison to Ichinoya, Hirasuna is much, MUCH more lively than Ichinoya; I suppose this is because its closer to the city center.

Anyway, the festival is one of the two festivals held at the University, the other one being the University Festival which is held sometime in October. Organised by students, there are performances ranging from dancing and singing to talent shows, and of course food. I had no idea that the festival would be organised on such a big scale so I hadn`t taken my camera, unfortunately. The festival reminded me of the carnivals and festivals back home.

We hung around for around two hours watching some talent shows, during which met up with Jurate`s friend Kristina and I also met up with Ronit briefly. At around 10pm, the festival was concluded by burning a huge bamboo structure, which Ronit told me represented a Kanji character. We then met Kristina`s friend, Adrian from Mexico and headed off to a Mexican restaurant, El Torito, for dinner. This was to be my first Mexican food.

After dinner, we met up with some more of Adrian`s friends and went to this Izakaya but it was really small and crowded, so we went to Cyberex, the amusement center that we had went to the weekend before. We signed up for four hours there, playing pool and table tennis and when we finished, it was 4am and dawn had already started to break! We then rode back to the University and parted with ohayo gozaimasu (good morning). It was about 4.10am when I reached my dorm room. I had signed up for a free bus trip that was organized by the International Student Center and Joyo bank and was supposed to convene at the Int. Student Center at 7.10am but I decided against going.

I woke up late the next day, lazed around, dozed off again and woke up again and soon found out it was 6pm! I had got bored with staying in my dorm room all day long so I again went to the Hirasuna Festival with a friend, Tito from Bolivia, who`s also in the same Japanese language class as I am. But this time, it wasn`t so much fun as it was raining. There were no food stalls. The only highlight was a beauty contest in which all the contestants were wearing Kimonos. After watching the crowning, we were about to return but saw that the finale of the festival was yet to be...a fireworks display....yes, thats right..a fireworks display in the rain!...it was quite impressive. An entire carpark was cordoned off and fireworks were launched from there. Back home, we didn`t have such big fireworks even for Diwali! I managed to get some pics on my cell phone. At times, the carpark looked like a small war zone with so much fumes. By this time, it was raining heavily and Tito and I went for dinner at a Chinese restaurant nearby. We were thoroughly soaked when we returned back to our dorm.

We have again rescheduled our plan to go to Ushiku next Saturday. But that's going to be a little problematic as I also have a robot contest in my lab the same day. Lets see if I can juggle both events together.

Watashi no Kuni (My Country)

We gave a presentation today about our countries in the Japanese language. I wasn`t looking too forward to this as having studied the Japanese language for only about 6 weeks now, a presentation was not something I felt I was ready for.

First I had problems writing my essay. Luckily a Japanese friend, Haruka-san, was kind enough to translate my essay into Japanese for me and had it not been for her, I wouldn`t have been able to finish it.

I was then unlucky enough to be the first presenter and when I stood up in front, I forgot some of the lines I had memorized. (We were told that we had to memorize our essays and that we wouldn`t be allowed to read. I found this very unreasonable).

So, I`m not feeling too pleased with myself today as I think my presentation wasn`t so good. I have a Kanji test this Friday and I think I should make it up by studying for it.

I`ve been to Ushiku Daibutsu too....not!

Yesterday, we were supposed to go to Ushiku to see Daibutsu, the world`s largest statue of Bhudda. I had bought my Sony Handycam Camcorder specially for this trip and fifteen of us turned up at Tsukuba Station but to our dismay, Naoki had an outdated bus schedule with him and we found out that only bus bound for Ushiku had already left!

Disappointed, the group split and some of us went to Tsukuba Botanical Garden to kill some time. We hung around for around an hour before returing back to our dorms.

At 7pm we met again, this time it was only Jurate, Naoki and Sato and me; we first went for dinner at a Chinese restaurant near Hirasuna and later, we went to Karaoke and spent two hours there.

From there, we went to Cyberex, an amusement center in Tsukuba and played pool and table tennis. Jurate teamed up with Naoki against Kristina and I and although they defeated us in the first two rounds, we were victorious in the 5th game. We then played table tennis till 1.30am and then returned.

We`ll go to Ushiku Daibutsu next Saturday....hopefully.

If you`re buying a cell phone in Japan...

I received my first bill for my cell phone this week. How much? 7,200 Yen!

So if you`re thinking about having a cell phone in Japan, it`ll pay to think twice (or thrice!) about which phone company you want to subcribe to. I got myself an AU deal at the advice of my tutor but most students in Japan use Softbank. When buying, I couldn`t get the answers to all my questions, thanks to the language barrier, so I had no choice but just to buy one and so when I received my first bill, it was a real shocker. I then took Ronit (thanks bro!) and went over my phone plan once again and downgraded some of the features that I had initally subscribed to.

Today, I bought the latest Sony Handycam currently available on the market from Ishimaru in Tsukuba and I`m feeling very pleased with myself as I bought the handycam completely alone using the Japanese that I have learnt over the last 5 or so weeks. Costing me $125,000Y, the HDR-SR12 Sony Handycam Camcorder has a 120GB hard drive, is High Defintion (HD) with 1920x1080 recording, with Face Detection technology and ClearVid CMOS sensor...impressive desu ne?

Roboken Open Lab, Tsukuba Festival and Roboken BBQ

The Intelligent Robot Laboratory (Roboken) and some other labs from the Department of Intelligent Interaction Technologies held their Open Lab day on Saturday 10th May, coinciding with Tsukuba Festival.

There were two robots in particular that intertested me...one was from my lab. It was a small differentially driven robot with a laser range finder that detected a human in front of it and followed it autonomously...if one walks away from the robot, it commences it`s human-following behaviour and if the person walks towards it, the robot backs up...although its electronics and behavior was elementary, the robot looked quite cool executing this human tracking behaviour. It was also robust enough to follow just a single person most of the time even if a second person came in its way.However, the response time of the laser range finder was 0.1seconds so if one steps away from the robots quicky, it loses track of the human. Here are some pics and vids.

Later I went to the festival at Tsukuba Center, with Ronit, where there were food stalls from various countries. I had a chicken kebab from an Iranian stall. Unfortunately, it rained all day long so we couldn`t stay there for long.

The next day, Sunday 11th May, Roboken lab held its annual BBQ. It has become somewhat of a tradition of Roboken to have its BBQ annually, around end of spring time. This year the plan was to go to Hitachi but due to the rain, we went to Yukarinomori instead. This is quite near the University. Yuta sensei explained to me that he had observed that students worked indoors most of the time, in a closed environment and so he initiated the idea to take the entire lab members on excursions, for a break away from the lab. The Roboken members had also gone for a 6 hour hike to some mountain during the Golden Week but I had gone to Tokyo the same day.

The BBQ event was quite fun as after lunch, we (boys and girls) played soccer on a muddy field and got ourseleves thourougly dirty.

And the Whole World Shook...

The talk of the day today was the series of earthquakes that struck us in the early hours of the morning today.

It was around 2am when I first felt small jolts. Having already experienced some earthquakes in my first 3 weeks, I ignored it and concentrated on trying to sleep when a slighly larger one caught my attention. Even then I did nothing initially as I trusted Japanese construction. But when the next quake struck and brought down some of the stuff in my shelf, it had me up in a jiffy.....outside I heard some of the other guys from my dorm who had decided to go outside. Not only was the quake strong (and I mean STRONG), its duration was also scary...it went on and on for several minutes as if someone was trying to demolish our dormitory.

Later in the day, one of my senseis told us that the earthquake measured 6.8 on the Richter scale...lets just say that as far as earthquakes are involved, one experience is enough for me.
