Let's Make Robots!

Servo

Navigates via 3 Sharp IR detectors

This robot uses Mark Tildens H-Bridge design for motor drivers. The brains of the robot is a HEX inverter that until the Sharp IR detects an object the motors go forward.

This is the schematic for the SHARP IR  detector.  I have all the schematics, but i dont have a scanner to get it off of my notebook so i apologize for the quality.  the state of the motors are either forward or reverse depending if the IR detects any object.  output 2 and 4 go to the forward and reverse input of the h-bridge. 

 

I used the wheels of an old model airplane and just screwed them to the servo hornes. 

 The servos are hacked...basically means i took out all the fancy stuff and just hooked two wires straight up to the positive and negative terminals of the motors.  Also i had to take the mechanical stop out of the gear so that it could make a full 360 revolution.

Here is a picture of the electrics.

haha voodoobot is funny

Yes he is :)

However, he was referring to your use of capital letters, just as I was earlier, when I wrote to you about it. It is called "Shouting" in internet lingo, sorry if I was not clear in my mail ;)

I have now edited your entire post for you, and transformed the places where you wrote with CAPITAL LETTERS ONLY to a more pleasant format to read.

Please, in the future, do not use Caps Lock, do not write with capital letters where it is not needed. And I will repeat myself from when I wrote to you; It is all in the Rules (top menu), that I will ask you to read, and which you where asked to read upon registration.

Thank you for joining in on the site, and sorry for the non-robot-related welcome :)

 

Thanks for posting your robot on LMR. Aside from reading the rules and not SHOUTING your post at us could you post more information. Schematics would be a good start if it is a beambot. Tell us why you made it, how you made it and how you overcame any difficulties in making it.

More photos are also important.

Caps lock broke?

Oh come on KL, can't you tell it's the hex inverter at work here....
