MOBOT 2003 and 2006 videos
« on: May 31, 2008, 02:13:45 PM »
This was my very second robot, named Pikachu, that I entered into MOBOT 2003. The video starts off showing what it looks like, followed by a big Pikachu thing on top of it as it goes down the course.

Pikachu used a CMUcam and a Cerebellum (PIC16F877) microcontroller.

The reason it failed on the hills was mainly a result of having poor speed control. Plus, I sucked at making robots back in 2003 . . .



This is Hex, the first hexapod robot to attempt the MOBOT course.

It was built by my friends Pras and Rich, and uses my CMUcam code from my Pikachu robot.



This is Pikachu IV, a simple photoresistor line follower robot that I entered into MOBOT 2006 at CMU.

Its fully documented here with source code:

How did you mount the standoffs to the sides of that thick hdpe on pikachu IV?

I bought the metal standoffs from radio shack and the screws are too short to mount to 1/4" thick hdpe.

obvious thought was to get longer screws, but going to hardware stores, I have been unable to find ones that fit.

I simply drilled holes into the plastic, and then screwed the spacers into the holes.

The holes were drilled to I think .106" diameter, and the 4-40 spacers (1/4" long screw) I used were more like .116". It self-threaded really easily.

i'm confused....

My standoffs have short screws at both ends.

Are yours not like that?

Mine looks like this. The bottom has a screw coming out. The top has a threaded hole so that I can put a screw into it.
