Let's Make Robots!

Bandit @ 13:00 - Part 4 XBees (Plus Extra :- EPP Flying practice)

Project "Depron" took one leap forward , with the successful implementation of the XBee Pros and Servo mechanisms.

This is a key part of the project, which means that i can now rest easy that i have 1.5Kms of control over the plane.

It was no easy task to find compatible libraries for the Serial & Servo control,

In the end a combo of the NewSoftSerial.h and ServoTimer1.h was the perfect match for the XBee Pros, the whole system is running rock steady @ 38400Baud (@momo).

Arduino XBee Serial Multiple Servo Solution

Here i present my Arduino XBee Serial Multiple Servo Solution

Here is a Sketch of the system (apparently sketching your ideas is the thing todo...........)

I thought i was home and dry with my Depron1, Depron2 project untill i found out that mixing serial data and servos (ie >2 servos) with the Arduino environment is just not possible (due to the complexity of the multiple interrupts).

Error Correction - how can i do it

As part of my "Depron Project", i have made a XBee pro RF transmitter and receiver interface.

(it works very well, however my application will test it to its limits i guess......)

I would like the data to be 100% true. (else my 400gramme areoplane will just be a dot on the horizon - if you know what i mean)

My Question :- I have heard of error correction codes and would like to know what is the best way or method to follow ?.

My system is Arduino based ie Atmega328s.

My data string is so :-

Bandits @ 12:00 Operation "Depron" (Will Gareth take to the Air)

After a long absence from flying gliders and control-line aeroplanes, i have decided to take to the air again, with the experience/inspiration and ideas from LMR - i think i have enough guts to start right from scratch.

Yes you guessed it ........ this is not an "Off the Shelf" model, this will be a complete self build from solid floor to fluffy cloud.....

Mystery Summer Object 2010 (now revealed)

Summer Mystery Object time is here :-

What on earth does this "Something Else" device do ?........... what sane or  more fitting .... insane guesses do you have.

(at long last  my Avatar picture becomes clearer, dont let that distract you though, if you look carefully there are extra clues in the pictures)

Update1 :- Speed/Direction & Duty Cycle Potentiometers added

Update2 :- Binary Coded Switch installed - to help with the patterns - and two Hacked Nokia Lipos for "On the Road" use.

 "Wiieasy Rider" Nunchuck /Arduino hack controlling Tamiya Off-Road Car

Update :- Code posted

                  >>> Car Park Video of it in Action at end of Blog <<<

Goal:- Hack a Tamiya Off-Road RC car - and control it with Wii-Nunchuck controller

MonoCopter

Just what is the point .................. it impressed me anyways.

3 stage burnout, and what exactly is the point of the parachute............Duh

Why did i find this........... well i bought 4 rocket motors for 2 CHF (RRP 18 CHF) could not resist, dont think mine will be so effective though.

Mystery Object Time again

Yes its that time again...........Mystery object to be identified

What is it and how will it be used ?  (wild guesses also encouraged).

Only clue is that its for my latest Picaxe project (would you believe), and promises to be a cool addition ..... when its programmed..

Ok..... i could not wait to post some Video of Basic System
