The students at the University of Oklahoma have put together a robot that will surely join the other drones in our future robot overlord regime. This autonomous vehicle was produced to replace human security patrols which can be both boring and dangerous. Intent on delivering surveillance to most locations, an all terrain vehicle was used as the base. It can navigate by itself through an obstacle avoidance system and communicate video and audio wirelessly. After the break we’ll take a look at the systems that make this work.
The team implemented steering controls by mounting a geared motor to the front of the ATV. This steering motor interfaces with a gear they added to the steering column via a chain. Obstacle avoidance is facilitated by sonar sensors on the front and sides of the chassis. These sensors can detect ground level obstacles such as curbs.
The vehicle uses both pre-programmed as well as sensor-based behavior. To start, the patrol route is fed into the program. Once unleashed, the bot uses a combination of this data, as well as input from a GPS module, digital compass, and the range finders to complete its mission. All of these components are tied together by the onboard Toughbook in conjunction with a 16-bit microcontroller. A wireless router provides connectivity for transferring data as well as remote joystick based control if needed.

Project developers [Fares Beainy] and [Sesh Commuri] sent us their paper detailing the project (PDF). The readily available, inexpensive hardware used to complete this bot says a lot about how far we have come with technology. It shouldn’t be too much longer before this type of hardware shows up in your town sweeping the streets for criminal scum (or humans recently escaped from the processing facility).
Wow. This is awesome, because hey… free Toughbook!
Awesome. I would love to build something like this.
When I seen the title of this post on my igoogle i thought for sure we were all damned that there was going to be artificial software that one day would take over the internet. boy am I glad that wasn’t the case.
I support toughbooks in the field (posting from one now). I would hardly call them inexpensive (for that matter neither are ATV’s). But this is a cool project.
BTW, Thanks to all the HAD staff for straightening things up around here. You guys have been doing a much better job of late. Please keep up the good work.
I, for one, welcome our new robotic overlord.
(can’t believe nobody has said this yet)
It needs to go faster. That ATV is pretty much just idling along. I want it programmed to shoot guns at people while jumping over dead bodies at full throttle.
So what’s keeping me from scraping one of these roaming my campus for parts?
I had always wanted to build one of these to patrol my parking lot. Smaller based on a 2-cycle string trimmer engine (with better noise management), using skid steering. But thought GPS needed to be more accurate or come up with an alternate way of knowing its location (triangulation from radio pylons?).
To answer your question, I planned on a system that if it noticed it was moving, not under its own power, it would sound a siren, strobes, and communicate its situation via wifi.
that ATV is inexpensive. Looks like a chinese model that can be had for little over $200 new. Just google “Mini ATV/Quad Bike/50cc ATV | Yongkang Fulaitai Industry”

It needs to have some claws and a blinking red eyeball. Without those things it is just not very scary. A built in grenade launcher wouldn’t hurt either(at least it wouldn’t hurt the robot)
Wow that was really amazing its better for the product to be tested not by human coz its more safe for rather tested in person that was a good idea. Chinese ATV Parts
