Title: Need Help With $50 Robot Schematic Simulation In Proteus
Post by: Mahmud Shimul on February 07, 2014, 11:46:21 AM
Hi, This is my first post on this forum. I'm a high school student so don't have much prior knowledge of robotics. This is my first attempt at robotics.

Problem:
I made a simulation of the schematics of the $50 robot on Proteus. In my simulation the servo rotates a certain angle for a while than stops. It doesn't rotate continuously.

So I would really appreciate it if someone could look at the simulation and tell me what i did wrong. Thanks in advanced.   :)

Ok I found some problems with my last schematic. So I made a new one. I think the connections are all right. But for some reasonthe servo's rotate pretty much on their own (even without the LDR connections). So could someone please help me out with this and tell me what's wrong with my schematics  :-\

If you post a JPG or PNG image of the schematic and PCB layout, it would be possible for someone reading this forum to actually look it over and see if something is obviously wrong.
Posting design files without even mentioning which program they are for is unlikely to make anyone want to spend their own time, for free, to look for and solve your problem for you.

Well I did mention it was for Proteus  :-\ anyways thanks for your reply.  :)

The photovore relies on modified servos that go from position-seeking to velocity-controlling. It looks like you've used an unmodified-servo component in Proteus. Thus, the behavior would be to seek a position, not control velocity, for those simulated servo components.

Thanks for your reply. So is it possible to modify the servo in Proteus so that it will control velocity? (Sorry for being a noob. I just passed my high schools so I'm kind of a high school student so don't know that much)

I don't know -- you should check the manual that came with Proteus, or ask the makers of the software.

Ok. Thanks for your answers. I'll just start building it. Also can I add you to my buddy-list?
