Finally, a bot that pays for itself!

 

The challenge is this: make a piggy bank robot.  I won't make any "rules" in order to allow complete creativity, but here's the basic idea ...

Make something for halloween.

Animate a skull. Make a flying vampire bat. Make a lightshow to frighten the wits out of small children. Make loud noises. Use the "magic smoke" for effect! How about a scuttling spider?

Time is short. I'll try to give more notice next year!!

One ball robot

Here is a challenge, something I just thought about.

A Segway is a vehicle on two wheels that uses a gyroscope to keep the rider upright, accelerating the motors when the user tilts forward and slows down when leaning back so the rider doesn't fall.

This would create a two wheel robot, but if the motors were mounted at right angles and drive a ball in the opposite way a ball mouse works. One motor drives forwards and back, the other turns the robot clockwise and counter clockwise. If the robot tilts to the left, the motor drives to the right to stabilise. 

The Write-LMR-Challenge

The rules here are simple:
  • Make a robot that one way or the other writes either "letsmakerobots.com", or "LMR" the way you like it.
  • Shoot it on video, enter it as a robot.
  • Best entries will be promoted / used to promote LMR - Fame, envy, marvel, admiration and respect is the prize!

Your robot can shape the letters in clay, burn it on your sisters dog with a laser, build them out of breadcrumbs.. or draw it with a pencil on a piece of paper.

The Challenge

Not so much a complete robot, rather a very important robot component. The challenge here is to build a Microchip PIC based I²C to Bluetooth device.

The protocol used by the bus master to address device on the I²C bus is completely up to you but the end result must be the ability to send/receive information to/from a BlueTooth equipped desktop PC. (Edited 2008-09-13) Extra merit will be awarded for the ability to take input from a Wii remote.

Most of us make robots, and most of us make robots that can somehow manage to move around on a flat surface.

But.. Can you make a robot that can

Drive, crawl, walk, or jump around.. perhaps even avoid obstacles etc..

AND

Lay upside down

AND

If it is lays upside down, sideways, or in any position on a flat surface, will manage to turn itself around to "upright" and start moving again

Welcome to The Chair Challenge! (Part II - the real challenge)

I was in the middle of writing "The Chair Challenge" here on the site, and then we got server-problems with this site.

Result was that an unfinished competition went un air, unintended! And before I knew it, it was won by JIP with this robot. But then i realized that hes robot did not in fact circle all the legs of the chair, and he was disqualified!

Therefore "The Chair Challenge" is now "The Chair Challenge! (Part II)" - we try again, and this time the rules are a little different :)
