People Watcher (2)

When elder people went into Bath Room,Robot will sit beside the Door and Listen to Un-Usually Sound patten & wait for specific time. If people went into bath room for too long. Robot will nock the door or generate sound. If robot "hear" some un-usual sound patten . Robot will also nock the door or generate sound. If there is no respons from the people. Robot will make emergency call.
Sound like a real "Watch Dog".

Challenge Point 1 : How does robot know people went into the bath room ?

Challenge Point 2 : What is "Un-Usual" sound & How long to wait for ?

People Watcher

Purpose : Look after people especially elderly people's activity at home. To activate alarm when people are falling down.

Method : Use Differential Image to remove the background and tracking the moving parts of the Image (that is the people). Use 2D model to abstract the people's image and get the estimation of the people's gesture. Add a thermal image or remote temperature sensor or Microphone array to confirm the people's location.(No use in the bath room or kitchen) . And once the system found the people is falling down. It will generate noise to wake up the people. If there is no respone from the people, it will call out for help.

Technology Challenge :
Aware of People won't disapper even he or she is not moving.(Become background) Like siting or reading or watching TV or Sleeping.
Model of people's gesture image. (Maybe Multiple camera can make better estimation)

Lego NXT Smart Sensor Idea

I2C on NXT is very slowly. 9600bps.
If I need 6 IR Appriximate sensor's value, I need to read 6 time and send a lot of data. The simpleset solution is to use a MCU to integrade the 6 sensor and NXT can initilized every sensor's threshold. Say Front and Back are 50cm and Front-Left,Front-Right,Back-Left,Back-Right is 20cm the all we need is to read 1 byte back (0: Under threshold 1: Over threshold). If you need more threshold control maybe we can alocate 2 bit for each sensor. So it is still 2 byte. It will save a lot of time and much easy to make decision on NXT.
At least we can provide different mode of operation on Group of Sensor.

糞金龜上月球

剛剛看Discovery提到上月球採礦的挑戰我忽然有的Idea是學糞金龜對月球土壤噴上一種黏液然後就跟糞金龜一樣的把球滾大這樣子就不需要去挖掘挖掘就會有灰塵的問題(雖然月球沒風)而且像昆蟲般的腳在月球的沙地上應該也比較容易行走因為是把負載滾成球所以在搬動上應該也比較省力胡思亂想留個紀錄

PS.或許是個好玩的Project用NXT來做　"推球的NXT" 因為球會越來越大因此不能用個夾子包圍球　只能推著球跑

GPS Tracking + 2D Bar Code Camera

Desgin a GPS Traking device with a Camera .
The camera is just use for Read the 2D Bar-Code.
Define a 2D Bar-code to store the GPS location data.
So any GPS traking device with Camera can scan the bar code parse the data and store it for latter use.
