The Chassis Of The Future
By Luke Amos
Choosing a chassis is perhaps the most important and therefore difficult part of building a robot. You find yourself drowning in a sea of metal, wheels and shipping costs. Thankfully for us, one team member stumbled across on perhaps the coolest, the most awesome, the most futuristic chassis I have ever seen.
A problem in previous years has been finding a good way of mounting all components to the chassis. Previous attempts include screwing everything to a slab of wood, cutting holes into a plastic chassis and even supergluing the electricals. These attempts, while admirable in their undeniable success, left the robot looking somewhat shabby and basically awful. However, this chassis comes equipped with a plethora of holes into which we can easily screw our components. This should give a more polished final look.
The chassis is also adequately sized to give enough intimidation for the Pi-Noon challenge, though not too large as to make it large and clumsy for the Temple of Doom and Lava Palava challenges. Although the square design is crude, it leaves ample space within the allowed size parameters to attach all the mechanical parts we will be using.
However, these features are mere bonuses when compared to what you notice right off the bat: the wheels. This chassis comes equipped with four Mecanum wheels, which allow the robot to move in any direction without rotating. This is due to each wheel being covered in passive rollers. Certainly a major headache in previous years has been the prospect of rotating robots exactly, and so this chassis appears to make the task of movement far easier. Plus they look awesome.
We believe we have found ourselves a fantastic chassis that will take us to victory on the day of the competition. And at the very least we’re sure to turn some heads.
