『Tom』 shoots 『Jerry』 with camera

Mission

Tom Jerry

2009 9/18 Matunaga-Lab ARLISS Project 2009 3

Requirement & Design

Hand made Sun Sensor used for this requirement

Get out-put of Sun direction

Direction of 『Tom』 determined

The Position of the Sun determined by time

Sun Sensor

Requirement & Design

• 『Tom』 must know 『Jerry’s』 GPS data

『Jerry』 uplink the GPS position to 『Tom』

『Tom』『Jerry』

GPS data

2nd flight

2009 9/18 Matunaga-Lab ARLISS Project 2009 10

Result of 2nd flight

•22 Pictures(640×480picel)

•『Jerry』 uplinked data to 『Tom』(1time)

•『Tom』&『Jerry』 got their sensor data

•Rotation,Separation system worked

Success

failure

•『Jerry』 is not in these pictures

•『Tom』 froze 5min after launch

Example of pictures

2009 9/18 Matunaga-Lab ARLISS Project 2009 11

• Minimum success ○・separation system ・camera rotation system

・saving sensor data ・getting pictures

• Middle success △・communication Tom with Jerry succeeded 1 time

・Sun sensor worked

• Full success ×

・attitude determination failure

・taking a picture of launch site was failure

• Advanced success ×・Taking a picture of 『Jerry』 was failure

Success dgree(2nd flight)
