There are Russian robots on Mars??
Not funtioning ones. But they did get there first.
The overview of the Russian launches toward Mars
May 28, 1971 Mars-3 Mars orbiter/lander Orbited Mars; Lander failed upon landing
Aug. 5, 1973 Mars-6 Mars flyby/landing UR-500 Flew by Mars, landed capsule
Numerous later Mars missions planned by the Russians never quite got the funding they needed to fly their proven hardware. Their whole mission budgets were fractions of what NASA spends annually on planetary projects.
