Does the Rover come with a computer?
Our Rovers do not have computers inside them but the R&D Payloads do. We recommend that all new customers purchase an R&D Payload which comes pre-loaded with ROS and allows you to drive the robot around with a controller within 5 minutes of unboxing.
Want to use your own computer? No problem, just check out the rover tools on our GitHub page. Follow the readme and the menu options for install and the rest will be handled by the tool. This is the same tool we use at our production facility in Minnesota so it is always up to date.
Do the Rovers have encoders?
Yes, both the Rover Pro and Rover Zero use brush-less geared motors with encoders on the back of the shaft. The data from them is exposed in our ROS1 and ROS2 drivers. We recommend combining this data with IMU data using a Kalman filter. The ROS1 robot_localization package works well for this. We also recommend using different covariances when your stopped, going straight, and turning, because the encoders are very accurate when stopped and driving straight, but less accurate when turning becuase the wheels will skid. An IMU is very accurate when turning, but not when stopped, so these two sensors compliment well.
What sensors do the Rover have?
The Rovers Pro and Rover Zero have encoders, motor temperature sensors, and circuitry to report the battery state of charge. All other sensors are meant to be put into the payload. This is because sensor technology is changing fast and this allows for using the latest and greatest sensors without having to redesign the whole robot.
Can you convert a 2WD Rover to a 4WD Rover and visa versa
Yes, and its very easy. It takes about 5 minutes to convert from one drive type to another.
Can you ship to countries outside the US?
We currently ship to a limited number of international countries. Please contact us if you are located outside the United States and are interested in purchasing robots from us.
