Atmel @ the Silicon Valley Maker Faire – Sarge the home patrolbot

So the 2013 Silicon Valley Maker Faire was held this past weekend in sunny California, with Atmel’s microcontrollers taking center stage in many creations, both big and small.

Although it is practically impossible to list all the devices at the Faire with Atmel microcontrollers under the hood, we’ll be taking the next few days to highlight a number of projects we came across while walking the rather expansive Faire grounds.

In this article, we’ll offer up a closer look at Sarge the home patrolbot, designed by the RoboRadix crew. Sarge’s basic function is to roam around a home or apartment, deftly avoiding pesky obstacles and keeping an electronic eye on things when its owners are out and about.

Currently, the good Sarge is a work in progress, but we were able to get a basic rundown from the folks at the Faire. Unsurprisingly, the ‘bot is built around the versatile Arduino UNO (ATmega328) or MEGA (ATmega1280), both of which are powered by Atmel microcontrollers.

Additional specs include two 12 Volts DC motors from an old lawn mower, a Linksys wireless IP camera, one Piezo Buzzer, two 12 Volts DC motors from an old lawn mower, one Pololu dual VNH5019 motor driver shield, one ultrasonic range sensor, two Sharp IR distance sensors, one Breadboard and power supply, one DC/DC power supply single Output 3A 15W 5-pin, one Power-Sonic 12V SLA battery and two 9V battery holders and 9V battery.

Oh, and yes, a special shout-out to the cool R2D2 unit (courtesy of Camp Peavy and their home-brewed robots) that was sharing the same exhibit table as Sarge. Sorry Sarge, we didn’t mean to make you feel inadequate, but we just couldn’t pass up the opportunity to gawk at our favorite Star Wars droids.
