Ill enter Batmobile and Ringwraith.

BATMOBILE
Weight: 100kg
Shape: Like the Batmobile from Batman Begins (http://www.starstore.com/acatalog/Batman_Begins_Batmobile-L.jpghttp://www.starstore.com/acatalog/Ba...atmobile-L.jpg), except it has an arm going between the front wheels, with a flat plate at the end. It has a static spike where the exhaust is at the back.
Dimensions: 100 x 40 x 40
Speed: 20mph
Ground Clearance: 0mm at front due to plate on arm; 8mm at sides, 15mm at rear
Armour: 5mm titanium
Wheels: 4, outside robot
Power: 4 Perm 080s motors on 24V powered by 24V @ 12amp batteries
Weapons: At the front is a pneumatic lifting arm - it attaches at the top, goes down diagonally, inbetween the front wheels, and at the end is a plate lying flat across the ground to get under other robots. At the back, where the exhaust is on the real thing, is a static spike.
Srimech: Arm acts as srimech
Tactics: Run into opponents, lift them and carry them around, and ram them with the spike if they cant be lifted or attack from the rear.
Strengths: Good traction and pushing power; fast; manouverable
Weaknesses: Exposed wheels; high ground clearance; slow srimech
