First dunk of the bot in water

November 2, 2009

We performed the first dunk test of the robot yesterday. This is done by just hanging the bot in water from a crane. The flotation “syntactic foam” is not put on. The aim is to check for leaks in hardware, and make sure the entire system works in water.

Melting the hole took way longer than we expected. The day began by the hole frozen over with ice. Rest of the story in pictures below.

After breaking the ice, we put the heating coils in water to melt the walls of the hole. Kristof spent almost the entire day tending and moving the coils to get a smooth sided circular melt-hole.

I felt much better and was able to work all day, though still far from 100%.

Halloween

October 31, 2009

The day began rather badly for me. The dust-exposure had set my immune system into hyper-active mode. As a result I woke up with swollen lips and throat – classic signs of food allergy. I could not swallow even water. I started to panic a bit but ate an anti-histamine and took the day off. I slept for most of the day. Emma was a ray of sunshine all day and made  delicious pumpkin pancakes. First meal that I could eat in many days!

Maciej and Jim came by to the jamesway in the afternoon. They are having a very hard time getting the melt-hole right. First, the “hotsies” that are used to generate the high power necessary for melting the hole have suffered from frequent break-downs. Below is a picture of a hotsie that actually caught on fire last night. Second, the melt-hole quickly refreezes and grows a layer of ice up-to 3 inches thick. Maciej has also injured his arm and back due to all the heavy lifting and is rather in bad shape today.

The team came back in the evening when Emma had cooked an awesome dinner and pumpkin cakes for dessert. We all had a good time.

Emma gave hand painted and personalized pumpkin drawings to everyone. Mine had an empty "speech box" because of lost voice.

 

 


At Lake Bonney

October 28, 2009

Finally the weather cleared and the entire team had reached Bonney. We flew to help with the Bot-house construction at West Lake Bonney. The Bot-house is up and the carpenters are setting up the electricity and propane heating today. We took the morning off to fix up the stuff in our tent, and clean-up the East Lake Bonney living area.

It was a pretty miserable day for me yesterday.  The rooms at McMurdo are not cleaned for ages. In the process of vacuuming the room, I inhaled some dust that resulted in throat inflammation and trouble breathing. Getting sick in McMurdo is almost a right of passage – that’s what happens with 6 people per dorm room, multiple changing room-mates, almost  1000 people packed in small area, and hardly any cleaning of dorm rooms.

Anyway,  I hardly got any sleep the night before last, and then took the helo flight to Lake Bonney, and was out working (or at least trying to work) in the cold and it was pretty miserable. I did manage to stay warm and sleep well in my tent last night. I am much better today, though my voice is almost gone and I still feel a bit fatigued. Bill says that this is an adjustment phase and I will feel fine soon.

One of our ATVs ran out of fuel on the way to Bonney camp from Bot-house. This is about 12 min at about 10 mph.The other ATV had to run back to Bot-house to get fuel.
