As I promissed 2 weeks ago here are some pics from our Airship(unfortunatelly, no videos for now)
Behold my fleet of flying airship robots! The world will be mine to command and conquer!
Each ballon has about 300L of He and can carry a payload of 150~160g.
The robot uses the reading of a sonar and PID control in order to keep the height constant. The actual movement is done by a pilot using a futaba RC transmiter.
The task of the competion is to fly the robot equiped with a wireless camera over a bunch of letters randomly distributed in an indoors envirioment. There will be another person(team member) in a separated room with a computer conected to the camera and this person will try to read the letters. The score is mainly given by the number of letters this person reads correctly, time spent and a few parameters related to the robot(weight, volume, techology, originality and visuals).
The competition happens every year in Japan but it is an international event. There will be cotestants from China, Russia, EU and US.
Things to do:
->60% of the programming is already done(motor cotrol and sonar reading and the PID control fuctions). I have to finish writing the interface between the reciver and controller.
->Fill more ballons with He. Spare ballons for test and training. The guys that are responsible for the ballon part already prepared 25 envelops that are just waiting to be filled(have I told you we are building an robotic army). Hellium and plastic are free(we are being sposored by 2 companies! both the ballon plastic and He are for free).
-> I still have to assembly a spare payload just in case.
-> Decide who is going to be the pilot(cool) and the letter-reader(boring).
Fell free to add any suggestion.
