One month to build a combat robot.
Updated: Jul 17, 2019
So I've gone a bit mental and decided to cook up a new build for the Featherweight Championships hosted by Robodojo at the end of August. Originally I was just going to turn up, hang out in the pits, and watch some insane fights. However, I miss having any viable featherweights, and it's been almost 2 years since I've had a proper and reliable robot to bring to an event. Venator is incredibly outdated by this point and is crying out for a new version, so I've decided to finally bite the bullet to go ahead with Venator V3.
The CAD has been made over the course of 4 days. I'm actually quite happy with how it's turned out, considering my time constraints.
This new chassis is very different from the original version I designed over 4 years ago. The double wedge concept, while useful in a few matches, was more of a disadvantage overall and so it's been ditched completely for Venator V3.
To improve manoeuvrability, the new design has a bevelled rear, so the machine will be able ride off opponent wedges. Furthermore the ground clearance is now 10mm, even when the machine is inverted, so it can easily drive across uneven arena surfaces.
The poor front wedge was another design flaw that plagued the original Venator. In V3 a ground-scraping Hardox scoop will be mounted to the front wedge to hopefully get underneath other robots.
The quality that made the original Venator so successful was it's low weight, which allowed the machine to reach top speeds easily. In order to maintain this, the rest of the armour has been kept very lightweight. The thickest armour on board is the 15mm HDPE side panels. Everything else is 12mm, with an 8mm base and lid.
To further increase speed, I am building my own wheels. 80mm HDPE rods with bike tyre screwed around the outside, to give an effective diameter of 86mm wheels. This will give the robot significantly better traction than the blue bearing boys wheels previously used.
In terms of size, V3 is actually smaller than V1 in every dimension. This does mean the interior wiring will be very cramped again, but this should allow for an easier drive in the arena.
That covers most of the significant upgrades.
This is the tightest schedule I've ever worked towards. Will definitely be a challenge, and there's no time to waste! So with all that waffle out of the way - let the Venator V3 build begin!
