Hi guys!
I present you my sixth robot. It`s from plywood and it´s very light robot.
It can be moved in the middle.
He receives four strong (12kg/cm) servos modiefied for continuos rotation and four servos for control.
It can dance "sine or cosine" and it can overcome various obstacles
I wanted to actually write chalk "I Like LMR", but i need more time for programming.
Here some pictures:

This robot is so cool! I

Cool :D

very cool!how did you make
very cool!
how did you make the turning serrvos move so smooth?
@ Wed, 2009-09-30 12:20
It was very easy!
Look:
init:
b1 = 100
b0 = 225
b9 = 3
b10 = 3
b11 = 3
b12 = 3
servo 0,150 ‘ initialise servo
servo 1,150 ‘ initialise servo
servo 2,150 ‘ initialise servo
servo 3,150 ‘ initialise servo
servo 4,150 ‘ initialise servo
servo 5,150 ‘ initialise servo
servo 6,75 ‘ initialise servo
servo 7,75 ‘ initialise servo
servopos 4,150
servopos 5,150
servopos 6,75
servopos 7,75
main:
let b0 = b0 - b9
servopos 0,b0
servopos 1,b0
servopos 2,b0
servopos 3,b0
pause 50
if b0 < 75 then goto main1
goto main
main1:
let b0 = b0 + b9
servopos 0,b0
servopos 1,b0
servopos 2,b0
servopos 3,b0
pause 50
if b0 > 225 then goto main
goto main1

5 ***** for the concept and
5 ***** for the concept and for the design ;)
I wonder what you gonna do next :D

Thank you for your praise
Thank you for your praise.
Perhaps I'll write things on the pavement with chalk. I do not know, becouse I have a new idea - with "remote control".
@ Tue, 2009-09-29 02:22
Very impressive! I love how
@ Tue, 2009-09-29 07:34
No sensors!
@ Tue, 2009-09-29 01:21
Interesting design
so you used 8 servos?
@ Tue, 2009-09-29 07:27
Yes!
Yes,
Ii used 8 servos. four servo move the wheels and four control the direction.
