New Romi chassis
I am excited to announce the release of the Romi chassis, our new platform for mobile robotics. Romi is a 6.5″-diameter round chassis that includes all the basic mechanical parts that you need for a mobile robot: a base plate with integrated battery holder, motors and motor brackets, wheels with silicone tires, and a ball caster as a third point of contact.
The Romi chassis is designed to be extended. It includes numerous mounting holes and slots, including specific spots for Arduino and Raspberry Pi and a place in front for a second ball caster. The motors have extended shafts for use with Romi encoders in applications requiring precision. For power, you can choose between four and six AA cells; we recommend the Romi power distribution board for access to battery power.
As an example of what you can do, here is the chassis with a Raspberry Pi A+ and our A-Star Robot Controller mounted on top, with power, motors, and encoders all fully connected and operational:
