First robot :S

[hellsplumber]

Hi! I really want to build a robot but im not all that rich
I was hoping someone could tell me how to build a simple and cheap robot as this will be my first robot.
I will add weapons and other things later.Also,Im 16 so I only have simple tools (screwdrivers,plyers,soldering iron etc)
so welding is out of the question :sad:

Thanks,whoever helps me :wink:

Get some MDF wood plates, some cordless drills for the motors, and a cheap 40Mhz FM transmitter and receiver with 2 servos. Find a wiring scheme to use 4 microswitches and relays to forward and reverse the motors and use the batteries from the cordless drills to power it all. make sure you use failsafes for the radio channels.

Hope this helps.

Look through the Forum.
Click on Featherweights in the Bot building hints and tips menu on the left.
There are many threads for you to browse.

Where can I learn about them? Also, what is the lowest powered drill motor I should use? I have found some for £10 but dont know if thay are strong enough.
Thanks

Where are you from? It might be best to visit a live event. You get the chance to see the robots and ask as many questions to roboteers as you want.

Im 16 tho and doubt anyone will take me as Im the only one who seems to b intersted in it :sad:
Id love to go though Im asking questions to roboteers now
Do you know what the lowest powered drill motor I should use is?
Also,Il check the site and see when the latest live event is Id like to participate too when I finish this bot

Think of servos as a litte finger you can operate from a distance, and micro-switches as a doorbell.

you dont need a lot of force to push in the doorbell, just enough to activate it. Any standard servo will do that easy.

Im beggining to understand this now. Do you have a picture of how everything should be wired up/connected together?
Also,whats the minimum power of drill I should use for the bot?

Generic 12v or 14.4v cordless drills from Argos, B&Q etc will be fine. If you look around, some chain store or other will be selling them for £10 or so each. Better yet get down the car boot sales and pick some up there- my team-mate Woody seems to be able to find almost everything to build a robot down the car boots...

All low cost drill motors (exc. 6v or thereabouts sizes) provide virtually the same power output.

One source for pre-stripped drill motors ideal for robot use is my store http://www.gimsonrobotics.comhttp://www.gimsonrobotics.com

http://www.micro-maul.co.uk/images/howtofeather.jpgIve illustrated a basic robot wiring diagram here. Often The secondary (reciever) battery is often not needed as many speed controllers will take a small amount of power from the main battery to supply the reciever.

Are electric screwdriver motors not good/fast/powerfull enough? becuse I found some for £5 .Aswell, If I do buy from a carboot,then the motors wont be the same (brand,type,power etc.) so that wont be an option will it?
Nice shop btw.I might buy a couple of motors from you. Maybe you could make a special offer for me...
