Weapons

Our original design was a lift powered by two Parvarlux geared motors mounted at one end and driving external chains to plate wheels welded to the weapon. This was very powerful but also heavy and vulnerable to impact damage.

Clearly this was in urgent need of a redesign.

This latest electrical lift is powered by a single geared Parvarlux motor via a heavyweight chain to a torque limiting clutch (set to 50kg at 1 metre) mounted on a transverse axle. This axle runs between the wheels. Large aluminium plates bolted to the sides spread the load and support the weapon bearings. Interchangeable weapons mount onto this axle.



The weapon provides us with a self-righting mechanism. However, since the robot is largely symmetrical in three planes, i.e. it works just as well "upside down" or running "backwards".

Weapon Specification -

• Lift motor 7kg
• Lift speed 30 rpm at 36V
• Torque of lift mechanism 500Nm at 36V protected by clutch
• Electric lift about 100kg capacity depending on length of weapon
• Length about 500mm
• A replaceable component

This plough was originally designed for football.
It came in handy in the recent snowfalls.


The side bearings are each threaded to receive a bolt which easily allows quick replacement of the weapon during bouts. However, the entire transverse shaft may also be removed using one of two methods...

1. A joining muff on the shaft can be released to allow this component to be removed from either side.
2. Vertical slots in the side allow the shaft to be removed as one unit. The transmission chains must be parted to facilitate this.
