2 entries for Wales:

Name: Wheely Pure Evil (Thanks to Aaron for flipper rams and armour)
Weight: 100kg
Armour: 3mm Aluminium Boron Carbite (slightly heavier than Aluminium, but harder than Tungsten)
Speed: 18mph
Shape: Low invertible wedge
Weapon 1: Top hinged flipper powered by a 120mm pneumatic ram, working at 145psi fixed on top of the robot. At the bottom of the flipper there is a 5mm Grade 5 Titanium wedge extender, designed to get under any ground clearance.
Weapon 2: Top hinged flipper powered by a 120mm pneumatic ram, working at 145psi fixed on the bottom of the robot. At the bottom of the flipper there is a 5mm Grade 5 Titanium wedge extender, designed to get under any ground clearance.
Strengths: Powerful weaponry and tough amrour.
Weaknesses: Exposed wheels on top and limited CO2 on board.
Ground Clearance: 1cm at the back, 0mm on sides due to side skirts and 0mm at front due to flipping plate.
Srimech: Invertible.
Notes: The robot is powered by 2 S28-400 MagMotors running at 24v, which give 18mph top speed. The flippers are made from 4mm Aluminium Boron Carbite, and powered by 120mm pneumatic rams working at 145psi. Each flipper can flip roughly 1150kg each. However, due to the flipper set up, the robot can flip roughly 2300kg! The robot has hinged side skirts, to stop robot getting underneath. The skirts are made from 3mm Aluminium Boron Carbite, and are hinged so they run upside down.

Name: Bigger Bully
Weight: 150kg with heaviest weapon system on.
Armour: 5mm Hardox and detachable side, front and rear skirts made from 4mm Grade 5 Titanium.
Speed: ~ 20mph
Shape: Box with skirts.
Weapon 1: Interchangable weapon systems (See Notes)
Strengths: Strong armour and good pushing power.
Weaknesses: Hard to control at full speed, and cannot self right with spinning bar.
Ground Clearance: 0mm with all weapon systems.
Srimech: The robot is invertible or can self right using the axe or flipper, but cannot run upside down with the spinning bar.
Notes: This is the 2nd incarnation of Bully, my best shuffler to date. This version has kept the 5mm Hardox armour, which did itself proud, but the weapon system has changed a lot. Due to the varying number of vapourbots entering the competition, Bigger Bully now has interchangable weaponry, designed to kill a certain type of robot. The robot itself is powered by 2 LEM130 Lynch motors running at 36v, which give 18HP. This is designed to push other bots out of the way and into the arena walls or pit. There are 4 weapon systems, all designed to defeat a certain type of robot. These weapons are:
The top hinged flipping arm is the main weapon of Bigger Bully. It is powered by 2 50mm Dia High Pressure Rams fed off 4kg of liquid C02. It is capable of flipping 250kg, and also self rights the robot if flipped. The flipping arm is hinged at the back of the robot, and has a bungee cord attached to it, designde to snap the flipper back straight away, increasing momentum and thrust. All skirts are added to the robot, apart from the front skirt, which is added to the flipping arm, designed to get under and act as an Atomic 2 style flipping plate. The flipper has roughly 15-20 flips in it per fight. The flipper is used against flywheeled robots, FBSs, ramming robots, robots that have a high ground clearance, high pressured flipping robots and robots that lack srimechs (not invertible robots).
The robot also has an axe weapon it can choose from. The axe is Dominator 2 style, and is powered by a C40-400 MagMotor running at 36v. Due to the way the axe self rights the robot, only the front skirt is used for this system, aiding in manouverability. The axe can come down with roughly 4KJ of force, and can dent any armour up to 6mm Titanium. The axe weapon is used against robots with weak top armour and robots that do not have damaging weaponry, such as Velocirippa or Mighty Mouse. It is also used against invertible robots with inner wheels and robots that rely on a rollcage or rollover deisgn to self right.
We also have the choice of a pair of horizontal crushing jaws, powered by hydraulics. The robot can operate upside down with this weapon system. The jaws are mounted horizontally at the front of the robot, and are powered at 2700psi with a flow rate of roughly 4.5 litres per minute. They can roughly crush 5 tonnes at the tip. No skirts are used for this weapon system, due to the invertability of the design. The jaws are made from 5mm Ti/V alloy, with diamond coated tips, designed to get through anything. When the jaws are embedded in another robot, Bigger Bully will push them into the pit, or into a house robot. The jaws are used against robots with low traction and robots with no skirts. It is also used against clusterbots and invertible robots with outer wheels.
The final and most deadly weapon is a 10kg horizontal spinning bar made from Ti/V alloy. It is mounted on top of the robot, meaning that if it is flipped, it cannot run upside down. However, all the skirts are added, which give 0mm ground clearance all over. The spinning bar is powered by a C40-400 MagMotor running at 36v, and is geared down 6:1, meaning that the bar spins at roughly 5000RPM. The spinning bar hits with a lot of force, and can damage most armour. This weapon system is used against axed robots, robots with no flippers or lifting devices, also against poorly armoured robots and axelbots (both without a flipper) and crushing robots.
I would like to finalise my weapon choice before every fight, if I may.
