Ill enter Drilla Killa 7 and Tenderizers Revenge 2.

DRILLA KILLA 7
Weight: 99kg
Shape: Low invertable box, painted red, with a Tornado-like low wedge at the front, and an upside down one at the back for when the robot is upside down, and skirts at the sides fixed at the centre so they work whichever way up the robot is
Dimensions: 110 x 40 x 25
Speed: 17mph
Ground Clearance: 0 at front due to wedge; 0 at sides due to skirts, 3mm behind skirts, 25cm at most at back due to inverted wedge
Turning Circle: 2cm
Armour: 5mm Hardox
Wheels: 6, inside robot
Power: 4 Perm 080s motors on 24V powered by 24V @ 12amp batteries
Weapon: Each wedge has a hole in the centre - inside each hole is a diamond tipped drill, spinning at 600 rpm, which comes out of the hole using a motor. It can come out to cause damage when an opponent is on the wedge, or can stay out and cause damage when the robot rams opponents.
Srimech: Invertable; cannot rest on sides due to skirts
Tactics: To get under unskirted opponents, slam them around and bring out the drills to damage their underbellies; to ram skirted opponents with the drills out and try to cause damage
Strengths: Good pushing power
Weaknesses: Drills may not penetrate very thick armour; high ground clearance at back

TENDERIZERS REVENGE 2
Weight: 97kg
Shape: Low invertable box with low wedge at the front and inverted wedge at the back - painted blue with its name painted to look like blood on the skirts
Dimensions: 90 x 90 x 20
Speed: 15mph
Ground Clearance: 0 all around due to low wedge and skirts, 2mm behind side skirts, 20cm behind skirt on inverted wedge. Both wedges have skirts attached to them at their edge. The wedge and side skirts are attached to rotatable cylinders inside the robot (or wedge) so they can be moved up and down. When they are down, they are very low and its hard to get underneath, but the robots speed is reduced to 9mph. The side skirts can go up to a point where they work inverted. The skirts on the wedges move within 90 degrees - when their wedge is inverted, they are in a vertical position to repel flippers, and when their wedge is right way up, they are in a horizontal position, riding along the ground to help get under robots. When the robot is moving around normally, all skirts except the front wedge one are pulled down low but not to maximum lowness so it can move quickly - the skirts go to maximum lowness if a flipper comes anywhere near it.
Armour: Main body has 5mm polycarbonate on top of 5mm titanium, skirts are 4mm titanium, wedges are 5mm hardox
Wheels: 4, inside robot
Power: 4 Perm 080s motors on 24V powered by 24V @ 12amp batteries
Weapon: An electrically powered lifting arm, which runs along half of the top of the robot - its tip is pointed to help hold onto robots, and is at the point where the wedge meets the body, and it does not go down the wedge. It can rotate through 360 degrees so it can be used when the robot is inverted.
Srimech: Invertable - arm will act as srimech, but this will hardly happen as the robot works identically both ways up. Moveable skirts prevent it from resting on its sides.
Tactics: Run into opponents, try to get under them, then get them onto its top and onto the arm. The arm turns them over, or catches them so I can carry them around.
Strengths: Decent pushing power; moveable skirts; difficult to attack by flippers
Weaknesses: May struggle to use arm against some opponents
