A Short Robot Video

In my last post, I talked about the instrument driver for a Hokuyo LIDAR that I've been working with. The new driver that supports more models (and supports them all better) will be posted to IDNet in the next week or two.



I thought I'd show you how I was actually using the LIDAR. Meet NIcholas, a robot I've been working with for the last few weeks...





NIcholas is based on a radio-controlled car platform, but is controlled entirely by the on-board single-board RIO computer running LabVIEW Real-Time and LabVIEW FPGA.



Single-board RIO is an OEM-able circuit board that contains both LabVIEW Real-time and LabVIEW FPGA targets. It's similar in functionality to the compactRIO platform. I'm using the Real-time part for processing the LIDAR data, and the FPGA for controlling the motors and steering.



I didn't build NIcholas myself; he was built by an intern last summer. As a research project, I've taken him under my wing for a while to learn more about LabVIEW on the RIO platform, and a little bit about robotics.



NIcholas doesn't have much of a mission, yet. He just drives around autonomously and tries to avoid obstacles. The LIDAR is used to detect obstacles and find the clearest path to take.



Here's a short video showing NIcholas in action...
