Trying to use ArduSub to control a student built ROV. We’re very new at this and are having some difficulty making things work. I know this question may seem silly, but is a companion computer (raspberry pi) required? We’re using the Fathom S tether boards with the topside board connected to the laptop via USB.
Hi Brent, in this case, you do not need a companion computer!
The role of the companion computer, or Fathom S is to
- transmit video from a camera to the surface
- transmit information between the pilot and the rov control system
The Fathom S accomplishes both of these, but in a different way than the companion computer:
|Video camera support||autopilot / control system link||Topside outputs|
|Fathom S||SD, analog||serial TTL UART||1 SD analog video out + 1 serial (TTL OR USB)|
|Companion Computer||HD, digital||serial TTL UART||1 ethernet network|
Excellent. That was my thought. Guess we’ll have to do a little more trouble shooting in that case.
What is the trouble?
