The InvenSense MPU-6050 sensor contains an accelerometer and a gyroscope in a single chip. It is very accurate, this sensor is used in self balancing robots, drones, smartphones, etc. The sensor uses the I2C-bus to interface with microcontroller.
This is our prebuilt HD2-S robot modified with a 5 axis robotic manipulator arm. This robot is loaded with all the options including a programmable Arduino. Ready to ship. We will supply the Source Code.
