COMPLEX Final robot
The final version of the robot was a bigger version of this robot. It should have more push-pull outputs
to support the motors for the arm, should be able to send back sensor information, have lights and have
a tilt option for the camera. I wanted to build it as universal and modular as possible. Later in the
project it proved to be a very wrong decission. The downlink was again created with of-the-shelf 433 MHz modules. The uplink was created by using the unused audiochannel of the 2.4GHz transmitter through FSK. In the final version, 4 circuit boards were interconnected with ribbon cables. The circuit boards had the following functions:
- Supply Board (fuses, regulators, voltage/current sensing)
- I/O controller board (AD-conversion all 24 analog inputs and generating 16 PWM signals)
- Driver Board (all 16 push-pull drivers for the motors)
- Communication board (433 MHz receiver and decoder, FSK encoder)
