Andron4000 HW crusher build

[Andron4000]

Hello Roboteers.

Lots of progress!

We received our Hydraulic unit today from relatedfluidpower.com
Attachment 6204Attachment 6205
They have been very helpful in helping us select the right unit and configuring it to be suitable for combat.
The solenoid driven valve, mounted on top has 2 positions for forward and reverse, rather than the usual 3 with the default position being all ports blocked.
The reservoir also draws from the centre instead of the bottom, which allows the unit to deal a little better with being inverted, or operate off centre.
It should give us our 8tonnes using a 80mm bore cylinder

We have also started converting our concepts into models.

This is the wheel. The idea is we waterjet the 'jigsaw' hub out of alu, and the complimentary tread shapes out of pu or rubber.
When the pieces get damaged they can then be switched out easily.

We have elected to go for the NPC-T64s for the drive (they are currently sitting in customs!), and decided to mount the wheels on separate bearings so the gearmotor will not see any side loading.

The next stage will be to choose a cylinder so that the weapon arm can be designed, concept shown above.
We also still have to decide on RC components and batteries/ chargers etc.

This is very interesting... I'm making a feather and due to the rules of most tournaments not allowing high speed spinners and too many flippers everywhere I wanted to do something else. A crusher is oen of my preferred options. However I'm not convinced they have a place anymore due to hardox.... so I have a question, what tip pressure would be required to pierce hardox of maybe 3mm to 5mm,, and what material would your tip have to be to accomplish this?? Anyone know? Or done it? Lol
