Do robots have personality?

Many sci-fi shows and books depict robots with personality, sometime as the result of an accident like the movie "Short Circuit", sometimes intentionally as in the movie "I, Robot". Now that I am working for Dagu I have discovered that even simple robots demonstrate personality.

How to send serial data after collecting data from different functions

Hi,

I need some help regarding my subject. My hardware is Arduino UNO. My setup is as follows.

I have 3 or 4 functions which collect GPS, compass and sensor data's. As telemetry i out put the data via xbee module wirlessly to my PC. My issue is when the data comes so fields missing due to delays on some operations. Example format of the data is lat,lon,heading,temperature,rpm. which is output from a serial.print

But when sometime due to some processes the some data misses. so tell me a way which i can do this much affectively.

autonomous, web controlled.

Found the correct motors for Leo

Well found the correct motors for Leo, less than a $10 fix, actually $7.16 before S&H. Polulu.com wants another $10.95 for S&H.  I don't mind paying for S&H but would rather wait till I ordered more than the S&H is going to be.  I might get a few extra motors to put on the swap board and see what I can get for them.  $20 for 4 motors, or $30 for 15 motors, you do the math and see what you come up with.

Hex Caster

Hex Caster is my attempt to come up with some play on the word "hex".

I plan to use this PCB with both my hexapod projects.

Here's the top of the board.

Below is the bottom.

The servo banks are broken into groups of six.

Heated Bed Warning Light

Hello everyone, I thought I'd share a circuit I am using on a little 3D printer upgrade project.

I have a heated bed PCB for my Printrbot that I am currently adding to the underside my aluminum bed. I needed clips to hold the pcb in place and provide a housing for wire strain relief. I designed some and printed them out. I wanted to add LED warning lights to the clips so they would glow when the bed was hot. I really wanted the lights to stay lit after the bed was off and slowly dim to nothing over about an hours time like the warning light on my stove does.
