Robot Rick has blown out his battery while trying to upgrade his software. You can help him recharge by giving him a Supercharged Battery. A regular Battery is not powerful enough. You will need to turn a regular Battery into a Supercharged Battery by using the crafting recipe listed here. Once the Supercharged Battery is crafted, give it to Robot Rick and he will give you a Level Up Mega Seed.
During the second Robot Rick side quest he will need a new Motherboard after your Supercharged Battery destroys his original. You can craft a Motherboard using spare junk and the recipe listed here.
