Let's Make Robots!


My First Bot missing a cable for the Sharp IR sensor

I found what I think is a matching cable on DFrobots under Arduino sensor parts as a Cable for Arduino Analog Sensors. It looks like the right cable. It is 3 pins with a JST type connector. It is the best fit I can find since Solarbotics no longer ships the IR Sharp Cable with the unit. DFrobots sells the same IR sensor with the cable and that cable matches the Arduino Analog Sensor Cable and the Sharp part number as “JST -3 Sharp” for the cable.

Mini Sumo Bot Parts!


I decided to make a mini sumo robot a few weeks ago instead of doing an obstacle avoider. Turns out that once you think about it, mini sumo bots and obstacle avoiders are pretty much the same! The only changes I would need to make would be to the code. Great! Sumos can also double as line followers. So in short, they're pretty versatile. Here is an image of most of the parts that will go into this sucker. 


IR Sensor Killer

Hi all,


My team is building a competitive robot as part of our course work. As all of us are using the sharp IR sensor, I;m thinking of ways to confuse opponent's readings.


So far, here's the list I've come up with:

1) mirrors to deflect IR--pasting mirror surfaces around robot

2) IR jam--using IR leds to shoot out beams in all directions


I'm thinking of using uneven surfaces that will diffuse the IR beam (not tested yet).


Any suggestions to disrupt the sensors?

Sneak Preview of Navigate & Map (NaM) (XMOS)

Well, here's the early beginnings of my Xmos project.

A dead PS2 mouse, a micro servo, a Sharp GP2D12, and a WowWee Bugbot.

Yes, this is half (well, okay, slightly less than half) of the project. Figure I'll just build one to start off. Once I make it work then it's easier to build the second one.
