Rocket launching robot - video now also on Youku available

Hi isotope,Yes, I

Hi isotope,

Yes, I considered to installing a camera on the rocket. You could also use a commercially available video cam model rocket like Estes Oracle Video Rocket or Estes AstroVision Digital Video Rocket (I think, this type is already out of stock).

I use a Chinese video capture, called "10moons".

Keep you updated

Thanks,

Will keep you updated :slight_smile:

 

very nice! do you make your
very nice! do you make your own rocket engines, or buy estes rocket engines?

Later I will make my own rocket engines
For first tests I will use commercial black powder model rocket engines, later I will make my own ACPC (Ammonium Perchlorate Composite Propellant) engines and rockets.

Yeah, that mix is powerfull,
Yeah, that mix is powerfull, i’ve made some myself with KNO3 and sugar, also made a black powder one(very powerfull) never made rockets though, just strapped it to a small RC car :stuck_out_tongue:

MarkusB is going for the moon though.

Really!

that thing looks nice and dangerous :slight_smile:
like the wolrds wobbliest mobile ICBM platform :smiley:

Wait
Wait till you saw it in action, hehe :slight_smile:

Let’s say
Let’s say we try it. It’s a lot of fun anyhow :smiley:

Seriously trying to go to

Seriously trying to go to the moon is a lot more impressive than not trying!

IMHO :slight_smile:

Formulations
be careful what binder you use, and be sure to have an anti-static pad handy, most ACPC formulations have aluminum or magnalium in them, a little spark could ignite the mixture. I suggest using a Potassium Perchlorate, Sodium Salyclate and petrolium jelly fuel (Whistle mix) it is less sensitive to static and has more thrust than amonium perchlorate based mixes. Just be careful with Whistle mix as it is shock sensative, so you must press the engines. (Pyrotechnitian in training, lol) Go check out Pyroguide.com for some formulas, read up first, and BE SAFE

Thanks for the tips

Thanks for the tips. A very good idea in chemistry is always to start with very small amounts :slight_smile:

I while ago we did an experiment for a Moon firework rocket design to celebrate a sucessful landing. You know the relation of Chinese to fireworks…

Here is the video of the experiment: http://www.youtube.com/watch?v=_zVO4jr1lIU

 

Hey, I like your tactile
Hey, I like your tactile sensor array, very crafty.

New video

Just uploaded a first video of the robot - obstacle avoidance and ignition system tests.

Hi fine

Hi fine project…

May i know…

how much you had spent for the rocket?

The rocket

For the robot I have not selected a rocket till know. Probably I will go for Estes RTF model rocket SkyTrax, easy to fly and some place in the nose cone for the transmitter and battery.

For the first R/C controlled prototype I used a Chinese model rocket, around 25 RMB, including rocket motor C6-4. BTW, not so easy to get model rockets in China. It’s normally only allowed for educational use and reserved for schools and universities. And this in the country which invented the rocket :frowning:

This would look sweet as an

This would look sweet as an onboard camera:

for that price i guess it’s easily replaced :smiley:

Thanks

Wow, thanks for sharing your work with us in such great detail. The picture tutorial is amazing. I really enjoyed checking it out and will be back to see how far you have come and what else you are doing.

Gambling your life savings is not a good idea but at this casino online you may end up with enough casino cash to add to it.

Nice Job!

Nice one.  Would there be any advantage to making your wheelbase longer / wider for a more stable run. 

Looking at the distance the payload travelled I wonder if your launch pad was truely horizontal / vertical - do you check somehow to ensure that the launch pad is horizontal when selecting your launching position?

Thanks, Pete :slight_smile: I had no

Thanks, Pete :slight_smile: I had no problem with the wheelbase regarding stability. The launch rod ( Ø 3 mm stainless steel) and rocket are shaking a little bit too much. I think I will use a kind of trail for the next version. The rocket in the video was launched vertical (90°). The launch pad is adjustable from 45° to 90°. Now only manual, later a servo will do the job, controlled by a inclination sensor, so the launch pad will always be in the right position, independed from the inclination angle of the rover. BTW, the launch angle should be not less then 60° to avoid sombody get hit/hurt by the rocket.
