Developers, hobbyists and robot enthusiasts looking for a way to easily build complex robots using Adafruit’s range of Feather boards, may be interested in a new shield created by David Bershadsky and Alexander Kirillov. RoverWing is part of the Microchip Get Launched design program, using the SAMD21G microcontroller.
The RoverWing uses same connectors for the battery, motors, and encoders as the REV Robotics Expansion hub used in First Tech Challenge robotics competition, so it can be easily used with the same motors and sensors. It’s creators explain a little more about the inspiration and design of the Feather shield.
“RoverWing is an expansion board (or “wing”, following Adafruit’s terminology) for Adafruit’s Feather boards. This wing provides motor drivers that can handle motors of 6-12 V, Inertial Motion Unit (IMU), and connection ports for servos, sonars, GPS, and other peripherals commonly used by mobile robots. All at an affordable price, with a powerful Arduino library, and excellent documentation. It also contains a microcontroller preloaded with firmware to control these peripherals, which communicates with the Feather board using the I²C protocol, thus freeing resources of the Feather board for other purposes.”
“The RoverWing can be quickly deployed in variety of DIY robotics applications ranging from simple cars to robot tanks, to bipeds, to segways, to any application you can think of that needs 2 high-power motor drivers as well as integrated sensors and sensor ports.
The RoverWing library allows it to be used by any maker regardless of their experience level, making it perfect for both educational settings as an introduction to robotics, as well for any seasoned maker looking for an all-in-one control board for their project.”
