I recently bought a DFRobot MiniQ v2 to evaluate as a possible pre-built robot to use in the robotics class I'm teaching.
Features
The MiniQ is small, but comes in a nice plastic case with a USB cable. (It also comes with another ribbon cable – I think it is used for add-ons, but not yet sure.) It has an intriguing mix of features:
- Built-in wheel encoders
- IR proximity sensors in front
- Left and right ambient light sensors
- An RGB LED (very bright!)
- Five line-following sensors underneath
- Three built-in pushbutton switches
- An HMC5883 compass module
- IR remote control unit (can be read through the IR proximity sensor)
There is no documentation in the box, but a Wiki and tutorial are available on the DFRobot web site, as well as other store sites that sell the robot.
