STUDY 1 - BODY CONDITION SCORING
OBJECTIVES
To evaluate overall animal health condition
To ensure positive effects and system efficiency
SCORING
5: Obese; bones cannot be felt at all
4:...
Hamster training
Training was done as usual using the scoring method and using positive reinforcement (food inside attractor). A board is secured underneath the latex to ease the hamsters' running...
Current Training Methods and Results
Training Procedures
Before, training was done with negative reinforcement (a lot of knocking and banging on the tank). This is not an efficient way to train the...
Training Progress
Meena, J and E (adult male Winter White)are undergoing training in the fish tank. The original training arena could not be used as the engineers are trying to fix the arm.
Meena:...
The current application hamster detection is based on white color detection and histogram detection. I have temporally removed the histogram detection from the application.
To reduce the...
Training Hypothesis
Hypothesis 1:
Winter White hamster chases attractor better than roborovski hamster.
Subjects:
E (Winter White), Meena and J (roborovskis)
Procedures:
The hamsters will be...
Body Condition Scoring can be sufficient data to show that Metazoa Ludens provide positive benefits for pet hamsters. They are able to exercise and obtain an optimum BCS score (adequate amount of...
Exact Procedure to Train Hamster
Materials:
• 5-6 hamsters
• Tank
• 3 Carton boxes (1 A1 or A2 size, 1 A4 size and 1 long)
• Tunnel attractor with different tunnel shape
• 1 long tunnel...
1) Training procedure for demo in LA:
- Omit special training (~ 10 mins). Try to control the food given everyday so that the hamsters will be more willing to chase after the bait
- Connect the...

Arm-chasing results are satisfactory
Each hamster will undergo 2 times of training daily: morning &...
White tracking is now complete. I don’t think there will be major change in it.
Removed the counter display from the main window and added a frame rate display. The frame rate is around 15. The...
Concatenation of wide char with normal char is apparently complicated. So instead of concatenating them I decided to display contents separately, calling Unicode display and normal text display...
Report: Week of 17th May 2007
1) During this week, I worked with Derek, Roshan and Joyce on the actuator subsystem as well as on the robotic arm. We rewired the circuits using multi-thread wires to...
Completed histogram based tracking application. Histogram based application may be difficult to use since we don’t know the histogram of the hamsters brought in USA.
I have written another...
Player health amount display is completed. Also number of gems collected display is completed.
The next task is integrating the camera code to the TCP/IP communication done by Karthik. TCP/IP code...
Progress Report: Week of 21st May
Robotic Arm:
In the last week, I worked on the robotic arm along with Roshan, Joyce and Derek. The pcbs were fixed and tested. The new batch of PICs arrived on...
I have spent some time understanding the overall structure of the game.
My first task is to add a timer to the game. It seems there is a timer already available in the code but it is disabled....
The actuator subsystem and software have been completed and tested. A summary of the major changes and new additions:
Protocol for PC-Master communication: The PC can check the status of master...
Converting DOS application to WIN32 is not seems to be practical at this point. So it been decided to keep the 2 applications as it is. That is the server will have 2 programs, one handling the...
Timer function addition completed.
Next task is to display all the messages in Japanese text within the application. For that the application has to be converted to work with Unicode fonts.
The cpp...
Most of the examples in the web displaying Unicode text have the application setting; Character set – Use Unicode Character set. When this setting is applied to the application it starts giving...
A quick update on a couple of things that I have been working on:
TCP/IP Network Layer: The earlier code has been replaced (was using blocking sockets and was inefficient). The current network...
