How to get Level 3 Certification in Honkai Star Rail
There's no question to answer for the next robot. Instead, you have to battle it to get the Level 3 Certification. These Automaton Beetles all share an Electric Element weakness, making Serval a good pick for your party due to her AOE Electric damage. The enemies are also separately weak to Wind, Physical, and Imaginary Elements too.

However, they're not very strong, so you should be able to defeat them with a party of any Elements, as long as your characters are strong enough.
After defeating the enemies, head back to the gate and pen the first gate into Svarog's base.

There's another hitch in the Astral Express crew's plans though, so prepare for a trip back to Rivet Town and a few more battles before you can come back to the Robot Settlement.
