UPDATE 11/1/2013

Only 18 more days to go! I've had some entries but I would love to see some more! I know a few of you are working away but don't forget that 18 days isn't a very long time. Remember, there are some great prizes up for grabs and I really want these to go to people!



I often get comments on my robot build tutorials along the lines of “Where do I buy acrylic?” or “Do I have to use those particular spacers and screws?”  I often reply with “It doesn’t matter! Use whatever you have!” That in essence, is what this challenge is about. I call this challenge the “Scrap Bin Challenge”. Many of my robots are made from cardboard, the most recent being my Tea Maker prototype.



There is only one rule to this challenge; your robot mechanicals must be constructed solely out of items that would otherwise be tossed out in the trash or recycling. You can still use all the electronics that you would normally, but the actual chassis, wheels, arms, anything, must be made from junk. Bonus points to those who also make their own boards and/or use basic tools such as scissors and hot glue.



The purpose behind this challenge is to show people that you don’t need fancy materials to make robots, robotics as a hobby can have a softer blow on the wallet if you are smart with the resources you have available. The budget is something I find to be quite a deterrent for the younger generation, showing them it can be done cheap will encourage them to try the same.



I will judge the competition. The winner will be, what I believe to be, the most creative and inventive use of the materials used. I say this as I don’t want all the entries to be coaster bots (enough with coaster bots!) let’s be creative!



I will set the deadline for the 18th of November, this should be more than enough time to create and program your robot. If however this deadline is unreasonable for a majority, then I will extend it.



Wheels could me made from cardboard circles, milk or soft drink bottle lids.

Chassis could be made from egg cartons, cheese containers or chocolate boxes.

Arms and support struts could be made from soft drink bottles or wooden skewers.




To enter you must create a robot project page and then paste a link to it on this page. Your robot page must have either a video or pictures showing the robots construction. I would also like you to explain what materials you used and how you used them. Remember I am judging this on creativity, if you don’t show or explain the methods you used well enough I will not see it for what it is.



Now what is a challenge without some awesome prizes!

The great guys over at Core-Electronics have been kind enough to sponsor this challenge and provide all of the prizes! I work for them as a blogger and I can vouch that these guys are the nicest folks around. They have a wide variety of products at great prices and I’m not just saying that! Definitely check them out.

First Prize:

Cherokey 4WD Mobile Robot

Second Prize:

38 Piece Screwdriver set

Sugru Multicolour pack

Third Prize:


Adafruit 16 Channel 12-bit PWM/Servo Shield

Let it be noted that this is not just an LMR comp, but is open to my YouTube watchers aswell, the competition is exactly the same apart from entry requirements:


I expect that LMR will be doing a marority of the creations though and I hope to see all prizes going to LMR peeps.
