Robin Söderling joined as Peace and Non-Violence Ambassador in 2011 together with his good friend the artist, painter and writer Ernst Billgren. Robin and Ernst painted their knotted gun together – Ernst dipping tennis balls into paint, Robin hitting them onto the knotted gun – and the sculpture "Tennis For Peace" was then unveiled at the Swedish Open tennis championships at the centercourt in Båstad.
