Interesting note: the UHABS-7 team originally chose the Arduino for the onboard “brain” for the recovery vehicle since team members have had past experience with using an Arduino. After talking with Eric Pilger from HSFL, he advised the UHABS-7 team that a Raspberry Pi would be a better alternative to the Arduino. A PCC and DMM were also created to compare different microcontrollers and microprocessors and the Raspberry Pi was selected as the best option.
