A. R. Rahman has begun  composing songs for the Rajini starrer 'Robot'.

Sources close to the music composer say that work has already begun in earnest as director Shankar is keen to start filming this August.

The director is on a location hunting spree while Rahman is busy composing the tunes. With Rajinikanth having completed the shooting for 'Kuselan', it looks certain that 'Robot' will begin this August.

'Robot', produced by Ayngaran International, will have Aishwarya Rai playing the heroine. The mega-budget movie will be shot in various locations across the globe.
