Hi,

Today, I was developing a log system to store data about the battery when a NXT robot with a rechargable battery has all system enabled. So recharged the battery and now I made a bluetooth connection and now the log system is measuring the battery effect when the robot has:

• 2 motors enabled and running
• 1 compass sensor enabled and measuring
• 2 ultrasonic sensor enabled and measuring
• 1 bluetooth connection enabled and communicating with android mobile phone.
• Platon Software running in the CPU’s NXT and storing data in the File System

With this experiment, I will know how long has the robot until the disconnection. Last year, I did a similar experiment but the robot only stablished a communication with a GPS receiver and the result was 9 hours but now my preliminar hyphothesis is less due to NXT brick has more sensors/actuators and the bluetooth connection was replaced to a Android Mobile Phone.

Note: When I finish the experiment, I will update this post.
