My First Project- Fred the Lobot (Lego Robot)

I am halfway through building the main body. I am awaiting more lego blocks as I have depleted my store of 1 by 4 and 2 by 4 pieces. When the servos and board have arrived I can begin mastering the connection process. I have practically finshed all the programming before any of the items have arrived.

Creativita that's what I did too, programmed before hand. I found it really helpful because I could see what I could do, then order the parts to do it.

Also I saw your robot picture, looks pretty sweet; but have you considered a PING sensor? that would allow it to roam around with out bumping into anything. Using one will really open more windows for your robot in the future.

Here is the guy I bought mine from. Its a really good price.

Thanks TXT, that's a great idea. Is there any particulary complex programming invloved? I would prefer that if I bought it I was able to make it work.

No programming. It works the same way as the servos. Here is how you connect it to the EZB:

• Connect VCC/b,[b]Trig, and GND to any of the digital pins.
• Then using a separate wire, connect the Echo to another digital pin, making sure this one is on the Signal pin, not ground or +5.
• Now its just a matter of configuring the Radar Scanner, Object, or Collision windows in the ARC.
• In those windows config areas, it will ask for the Trigger and Echo ports, simply note where you placed them before and select the pins from the drop down menu.
• To get the robot to scan using its head, open the Radar Scanner config and on the drop down menu for Servo Port, select the heads servo pin.

I hope thats clear enough for you. If you still have trouble, remember you can click the "?" on any window to be taken to the Tutorials page to learn more about it.

Hope this helped! ~TXTCLA55

Thanks again TXT. It would be perfect for me seeing that I am having a servo for head rotation. The price will definitely fall into my budget.

No problem, always glad to help.

The EZ-B has finally arrived after approx. three weeks (which I am quite impressed with). After the servos have been ordered and arrived I will be able to start building. In the meantime I plan to start testing of the EZ-B and a do a bit of polishing on my programming.
