In-game, "Elemental HERO Necroid Shaman", "Dark Jeroid" and "Magical Android" are also "roid" monsters on account of having "roid" in their name and as such can qualify for some support designed for the "Vehicroid" archetype. However, some of the "roid" support cards specify Machine-Type roids.
Informally, the "roid" cards are sometimes referred to as Vehicroids, which is technically a sub-archetype of this one.
Another highly used combo is "Chain Material" and "Vehicroid Connection Zone". The summoned monster will survive the effect of Chain Material (thanks to the effect of "Vehicroid Connection Zone") and you will have a very powerful monster on the field. This allows you to Fusion summon from your Deck in a similar manner to "Future Fusion". The only drawback is that you cannot attack the turn you use this combo, though it is negligible, as the monster summoned is impervious to effect destruction, and its effect cannot be negated. Prior to the release of "Stardust Dragon", this combo was considerably more powerful, since most players would be unprepared to deal with a monster that had this kind of protection; since almost all Decks now include "Stardust Dragon", cards that can work around this effect are far more commonly used.
A "Roid" Deck is typically a balanced Deck and does not have a regular easy to summon beatstick. The other weakness is that the more powerful the monster the more requirements it will have. The single tribute cards "UFOroid" and "Rescueroid" never exceed 1600 ATK.
"Ambulanceroid's" ability to Special Summon "Roids" added from your graveyard to your hand can quickly fill your field when using cards such as "Expressroid", "DUCKER Mobile Cannon" and "Monster Reincarnation". To fill the graveyard, cards such as "Hand Destruction", "Card Destruction" and "Card Trooper", and many other draw-for-discard cards should be used. "Jetroid" can be a handy card as your opponent may be reluctant to attack him, especially if you summon just him in ATK and leave you back row empty; this says to your opponent "I have a hand of traps and I'm not afraid to use them". If this doesn't work and your opponent thinks you are bluffing, you can activate the traps that you DID have in your hand such as "Mirror Force", and "Magic Cylinder" that might have otherwise been destroyed by cards such as "Mystical Space Typhoon" and "Breaker the Magical Warrior". "Armoroid" is often used as a finisher to clear your opponent's back row without triggering "Starlight Road" or "Stardust Dragon". Something this Deck must be careful of though is "Cyber Dragon" combined with "Chimeratech Fortress Dragon", however the Deck may choose to run these cards itself.
By using "Roid" effects to return "Roid" monsters from your Graveyard to your hand and Special Summon "Roid" monsters you can add Tuner monsters to make a Synchro-based "Roid" Deck. Use "Shining Angel" to get "Chaos-End Master" and use him to get "UFOroid". Use Tuner monsters to Synchro Summon powerful Synchro Monsters.
This Deck's main strategy is to summon a pair of "Armoroids" to the field. Cards that send cards to the Graveyard from your Deck (e.i. "Card Trooper") will help the Deck dramatically. You could select a "Chimeratech Overdragon" for "Future Fusion", and send "Cyber Dragon", two "Armoroids", an "Expressroid", and an "Ambulanceroid" to your Graveyard. Using the combination between "Expressroid"/"Ambulanceroid", they will be Special Summoned. "Limiter Removal" can double the ATK of the "Armoroids" to 5400, and attacking your opponent directly with both will allow you to win the game.
This build is mainly based around "Steam Gyroid" and "Ambulance Rescueroid". The Deck is based around using the weaker "Vehicroid" Fusions and equipping them with "Fusion Weapon" to make their attack higher than normal.
With cards like "Unstable Evolution" or "Solidarity", your "Truckroid" and "Steamroid" will be very powerful beatsticks. "Unstable Evolution" can also make "Submarineroid" a 2400 ATK direct attacking monster. And then you can wait until the opportunity arises for you to use "Chain Material" and "Vehicroid Connection Zone" to summon "Super Vehicroid Jumbo Drill" or "Super Vehicroid - Stealth Union". After this, boosting the attack of the Fusion Monster using "Limiter Removal", could be a good option, due to the monster's immunity of being destroyed by the effect of a magic card, so you would have a powerful monster with more than 6000 ATK, that would not be destroyed at the End Phase, proving you a good possibility to win this turn.
This combo renders your opponent unable to attack (without something like "Angel 07" or "Skill Drain"). You Summon "Ambulance Rescueroid" and "Decoyroid", and if you are attacked, "Decoyroid" takes the hit, and the "Ambulance Rescueroid" revives it. To prevent "Angel 07" or "Skill Drain", cards like "Pulling the Rug and "Royal Decree" might be good ideas.
