Banebots motor mounting

So i have a pair of banebots motors (http://banebots.com/pc/MP-36XXX-540/MP-36064-540)

I was working on the chassis for my latest robot, but, I could not find a suitable way to mount these motors on my plywood chassis. They have mounting holes, but they aren't very deep. Any suggestions?

IR Distance Sensor (not a sharp! wahoo) for my xmos project

 So I had an idea (because i i like building my own stuff) of an IR range finder very similar in fact to odbots attempt at a laser rangefinder combined with CtC's ir beacon. So a narrow beam IR LED is mounted on a servo or stepper (or several if more power is needed). A IR transistor (one of those TV remote receivers) is mounted next to it at a known distance inside a tube similar to that in CtC's design. The servo or stepper scans from pointing towards the sensor (near perpendicularly) outwards near parallel while the led is being pulsed at the appropriate frequency.

Subsumption Archecture

Hey all I found this very interesting idea in a book (The Robot Builder's Bonanza) for a way to code a robot. Instead of having a robot that merely goes straight till it hits something you have several "levels" or "layers" of code. The first one being an obstacle avoidance sorta thing, and then on the next level an aimless wander. This wander section of code which would ask the obstacle avoidance level if it was OK to move. If it was OK then the random wander would do its magic but if there was an obstacle then the obstacle avoidance would take over like a sort of reflex.

My New Robot Ideas

     Hi all, I have been mostly a silent observer (http://letsmakerobots.com/node/3817 is the exception). Anyways, a few days ago after talking to a CIA tech genius about robotics and the field of electronics I was inspired to build something again. I dont want it to be a small little bot that once the novelty wares off is imediatly sent to a shelf. I want it to be something slightly usefull, fun, and constantly runing. I have two cats and it would be excellent if this robot was like another pet.

Multi Temperature Sensor Reading and Recording Device

The video shows what it does, but I will explain again here. It establishes a serial connection. When one of the switches is flipped it starts collecting data from the temperature sensor once every however long I want it to be for how ever many times I would like it to take temperatures...or until it runs out of memory. When the other switch is tripped it shoots the data out into the debug window. The other sensors' data is random numbers It works better if you take data from a sensor that is actually connected :P. I have to get more of the sensors.
This is a robot I am working on to create art, I hacked an old RC car, but instead of hacking the car, i hacked the remote (the leftovers of which are on the hood … Read more


Im off to buy An RC car to create a robot first basic things (pre defined movement) then logic


Im will use an arduino Duemilanove
