Post Hybrid Robot: Lego plus Fischertechnik
here 2 views of my Fischertechnik-Legotechnik Hybrid-Robot
Legotechnik chassis
ft-/Lego-grabber arm with 5 (!) degrees of freedom,
1 Hitechnic Compass-Sensor,
8 Sharp GP2D12 IR-Distance sensors at a MightyDistanceMuxBoard
for detection of obstacles and grabber control (planned: 16)
6 NXT-motors, grabber tongs with 2 ft Pneumatic-cylinders,
2x 3/2-way magnet ventiles, compressor: Lemo-Solar ;
controlled by 2 NXT Bricks (to be connected via RS485 network protocol <--- still to be developed)
(to be extended by a POB cam and an ultrasonic bearing system for navigation <--- for this a US single shot mode needed...)

driving position: ... 600Q85.jpg

grabber 30% extended, Pneumatic-grabber tongs turned 80°: ... 600Q85.jpg

#define S sqrt(t+2*i*i)<2
#define F(a,b) for(a=0;a<b;++a)
float x,y,r,i,s,j,t,n;task main(){F(y,64){F(x,99){r=i=t=0;s=x/33-2;j=y/32-1;F(n,50&S){t=r*r-i*i;i=2*r*i+j;r=t+s;}if(S){PutPixel(x,y);}}}while(1)}
