In latter part of 2014 I was asked to review the new Nomad robot chassis from Actobotics. The article was in the March 2015 issue of Servo magazine. These are some images taken of the robot which adopted the name of its chassis kit. Nomad is a roving robot designed to participate in Magellan navigation competitions.
The chassis kit was slightly modified by with the addition of four shock absorbers and articulation of both suspension beams. I did this to help reduce shake and to help keep the body of the chassis more level while it navigates rough terrain. Nomad is driven by four 12v DC motors with a differential drive configuration. The main processor is a Samsung Galaxy S3 connected via bluetooth to an Arduino Uno with a custom shield. I chose to use the Android device because it has a number of sensors built into it such as GPS, accelerometer, etc. Not to mention the dual core ARM processor. To read about the build and my impressions of this impressive chassis check out the March 2015 issue of Servo Magazine. And be sure to check out the video below.
