So open minded, my thoughts fell out…

Vex Kit – OTW

Posted by Deliverator on November 24th, 2005

Purchased a Vex kit on eBay this week. I was a little worried about making the purchase, as the seller only had one purchase feedback (another vex kit), but I got him to send me a number of picture of himself, photo identity and picture of him holding the kit. The next best thing to information super-highway street cred is knowing where someone lives :) The box is coming from California, so hopefully it will be here by the end of the week.

After this week’s hacknight (which is deserving of its own entry) I headed across the street to Rob’s place. Rob bought a kit after I told him about the Vex system a few weeks back and he hasn’t been idle. I got to play around with his first creation, a highly modified squarebot. He changed the design to utilize two bigger, powered wheels, shifted the axle and added a tiny third wheel (which acts a bit like a caster). To this base, he added a laser pointer to the front and a plastic rod with string attach at the back; each attached to respective servos. In short, he created a robot to torment his cat! I got to play around with it for a few minutes in the parking lot in front of his place and took some pics. Rob was nice enough to loan me the programming interface. I am loading up all the VEX software and documentation on an old laptop, along with all the FRC dev environement stuff for the IFI mini robot controller. We are using the IFI mini robot controller in the ROV project. First/IFI has been using PIC18 chips for their controllers for quite a while. I am hoping that I will be able to figure out how to program the VEX controller without having to spend $100 on the official programming kit , which looks to be little more than a USB->serial dongle and the install files for the EasyC dev environment.

Here is a pic of Rob’s cat-bot:
