This device is based on the Cherokee 4WD mobile robot platform. As we need to use many interfaces and bluetooth, we chose the Bluno Mega2560 controller.
During the design, we select the "GoBLE App" developed by DFrobot (a bluetooth 4.0 remote controller particularly designed for iOS devices) as the main controlling method.
Add camera and WIFI modules, you can start the platform even when you are on a short journey or on a expatriate work, observe your pets at home, play with them and feed them happily...
