Mantis 2.0 build is in full motion!
Mantis V2 is designed to fix many of the issues Mantis v1 had. It's now on entirely brushless drive and lift motors for better driving performance. It's using 4wd belt driven drive pods with 80mmx50mm wheels for good traction. The frame will be made from 2024 Alu and the outer armour is a mixture of 5mm grade 5 titanium and hardox. Claws are now 5mm gr5 titanium too.

A big upgrade to the design is the new claw which uses only one motor to grab and lift, this will simplify driving and hopefully make the bot easier to control.

Some CAD pics, one showing the close up of the new lifter gearbox for extra lifting power (64:1 saturn, 2:1 gearbox, 3:1 pulley)
Here are some of the CAD renders. Close up on the lifter gearbox, hopefully a more robust solution than Mantis v1.

Drive pod bits, these are all 6082 alu with steel wheel axles and gears. Wheels themselves are cast polyurethane 60A using 3D printed nylon hubs and 3D printed molds.

These are all the nylon printed parts in one wheel pod:

And here is a jumble of bits in the works, upper claw, front armor pods, pics from CNC shop of frame in progress and the lift motor connected to a 64:1 saturn...

A fair bit left to do, but things are shaping up nicely. More updates to come
