The Avengers' public space also contained androids for Steve, Natasha, Clint and Sam (Falcon).
This was clear from the characteristics of each android.
Steve's android also had a shield, and it was a vibranium shield which could expand.
This was Tony's 'reward' after following Luke's suggestion in the wake of the incident with Ultron to return the 'stolen goods' to Wakanda.
As soon as he obtained this 'reward,' he gave 60% to Luke.
Although it was less than what the anti-gravity device had contained, Wakanda had still given him the basic process for making vibranium weapons.
At the same time, the Avengers and the Bat Squad became 'close friends' of Wakanda.
Natasha's android had the emblem of a black spider on its suit.
Clint's android had a Gatling-style quiver on its back. Coupled with the armor's power, he no longer had to worry about being unable to pull the bowstrings to fire 100 to 200 arrows.
