i want top build my 3 servo exapod like this one
it have to be half in size
i will try to use polymorph for legs and body
exapod wish double-malt beer during a cable download session =D
i have replaced the servo...
this one is fucked... i think it's a problem of the internal control sistem
please help me
i have a malfunction on a servo...
i can not figure the problem, sometime it seems a wire malfunction ... but when servo stops to work , if i touch the leg it start to meve, but it moves slowly, then stop again, some time if i touch the plug it start or stop to work.... but it seem it have lo torque...
it's awesome to work with poly...
it's a contiuous transformation during the building process
it have to be able to lock and reach the ragret then engage the target
i am not sure to use grindig claws cause to complexity
i was thinking to a saw operated by a pager motor
in order to acquire a proper alignment with the objet it have to get distance redings al close range too
i have tested ir led/diode (reflection) but it is not good
i will use a Sharp GP2D120 IR
and i will go blind under 4 cm
those are the answer i was looking for.... thank you m8s
i will report in soon...
well i have to explain more in order to obtain some support
Purpose of the robot:
it have to nav enviroment and lock on isolated thin vertical object like a bic lighter
then reach those object, and grind them with his claws... :)
It will have 3 servo for legs movement and a servo to swing the head.. on the head there are sensors and grinding claws
so it can sweep environment swinging the head sensor
Servos: Hitec HS-55 (http://www.robot-italy.com/product_info.php?cPath=85_28&products_id=461)
Sensors(under testing): PNA4602M (http://www.robot-italy.com/product_info.php?cPath=15_47&products_id=146)
well the problem is: what is the right power supply?
4x 1.2 v cells
5x 1.2v downregulated to 5v
Noise built a dozen bots and only now wonders about batteries... Funny.
Go for rechargeables if you intend to "use" the robot for more than just a demo video. Those are circa 1.2 V. Most micro controllers and sensors do not mind the "missing 0.2 V" in the 4x 1.2 V setup.
Five cells will not last (much) longer, unless you are using a very advanced DC-DC convertor. And even then, going down from 6 V to 5 V will not give you much margin or extra energy. Compared to the four cell setup.
thank you for the answer rik
i was thinking to 4.8 solution too
but i remember that 4.8 pack, when is full charged, can deliver more than 5v
so it may be hazardous for some 5v component ?
well now the problem is that sensor do not work
this is the tutorial i was lookin
excuse me for italian crap
