With ROB learn to PS his two projectiles, they are very easy once you learn the animations. This does a lot to hinder his camp game.
He has one of the best horizontal spacing games in brawl so instead of trying to beat him there, work on landing a dtilt or grab, anything that will put him above you. From that point on, the only options he really has are fast falled nair (which is telegraphed if you know the animation, up b or uair him out of it) and gyro wavebounce mindgames. I have yet to play someone who effectively used the second option, but I can see how it would be pretty good.
SO that's ROB above you, he is very easy to juggle and frame trap there. Another area you can really pressure him offstage. ROB's recovery, while really good for that purpose, is not good if you understand how it works. WHen he first activates up b theres a noticable period where he can't attack. He also cannot airdodge or special out of up b, he has to attack or land. You can abuse both of these to continuously deflect his attempts to get back on stage. So you can side b with impunity basically. If he does get to the ledge, ROB has a hard time getting back to the stage with his ****ty options there. He can do drop down double jump projectile, which is easy to see and easy to intercept with a fair or just shield it. He can drop double jump fair, which is easy to see coming and easy to punish with a uair OOS. He can drop down double jump air dodge, which is probably one of his better options, but there's big potential for landing a dsmash on that if you predict it. He can also try and robo burner above you and get to the stage that way, but because he can't dodge out of it its upb or uair bait against us.
And then theres dsmash infinite, which is a lot like ICs infinite in that ROB has to change his playstyle to avoid that range. He can avoid it, but that means sacrificing fighting in close range where he can do decently against us, and taking to the air instead where we **** him.
