Built to enter the Heavyweight division of Robogames 2017 Huntsman is a scaled up version of Avenger. It was built on the smallest possible budget and while it had issues driving due to weight distribution it performed well.
Unfortunately due to budget constraints Huntsman was unable to be shipped back to Australia and was sold at the event.

From Robowars Forum "Redrawn 50 times and the last few months. Started with HP pneumatics and changed to LP and then back to HP again. I've calculated that HP pneumatics will get 3 times as much energy into the axe and cost a third the price.
The model isn't finished yet but I'm behind in my timeline". 14/8/2011

From the Robowars forum "I'm going with an inverted wedge with 10mm armour on the front. Listening the the builders on Killer Robots it seems that 3/8" armour is considered thick on a heavyweight. The inverted wedge is because unlike everyone else I actually want to be on top of the other robot". 14/8/2011

From Robowars forum "A 100mm bore 150mm stroke ram with a 1" Burkert and no buffer. I've calculated that this setup will be fine and I won't need more flow as the axe will take 200ms to swing.
A low pressure setup on the other side of the ram will retract it and self-right but I haven't drawn the QEV because I don't know the dimensions, will need to buy one first". 14/8/2011

From the Robowars forum "The chain and sproket setup on the weapon axle is my biggest concern and I'll be tweaking this part of the design. I prefer a solid pusher and a twin chain for the return". 14/8/2011
