Crazyflie 2.1 Programmable Nano Drone - STEM Drone Bundle
Bitcraze has created a new kit for its tiny programmable Crazyflie 2.1 drone(ROS compatible). This time it comes with a radio amplifier and ToF sensor!
What is the Crazyflie 2.1 programmable drone?
Crazyflie 2.1 is the latest version of Bitcraze’s programmable mini drone. Ultra-small and particularly light, this tetrapod drone carries a wide range of equipment enabling it to communicate with a mobile device, steer itself using a 3-axis IMU, increase its autonomy with an on-board battery, etc.
- The Crazyflie 2.1 UAV also has an expansion header allowing you to add lots of UART, I2C peripherals, etc. within the limits of its payload capacity.
- This flying robotics platform can be programmed using thePython API. It’s an open-source project, meaning you have access to all the resources provided by the Crazyflie’s community of developers.
- To increase its communication capabilities, this kit also includes a Crazyradio PA radio amplifier, which is a dongle that will amplify the signal to authorise a communication between the UAV and its controller, from a distance of up to 1 km.
Create autonomous flight conditions with the Flow deck sensor
This new pack also includes a Flow deck v2 sensor. This distance sensor module has two complementary components:
- A ToF laser sensor allowing Crazyflie to calculate the distance between itself and the ground
- A PMW3901 optical sensor that can measure movements on the ground beneath it
This navigation module supplements the IMU already present on the Crazyflie mini drone. It also allows you to program the path the UAV must follow using the Python API.
