Walk straight, blasting away the Geonosians as you go. On your left, there will be a barrier to shoot with pale lego bricks. Shoot it, and go through the now open tunnel. In the screen right corner, activate the Artoo panel, then go screen left, all the way back, and then screen left again to find Windu.
