For 2020 CSB 2 will be rebuilt into CSB 2.1. A completely new chassis made from HDPE (there's still some Hardox and Aluminium in there) and features interchangeable wedges and side panels to fight spinners.

The Robot is slightly bigger and current weight calculations look to have the robot roughly 1kg lighter on the main configuration. The weapon has been improved upon the old one that suffered from some screw ups I made in the CAD. The weapon arm can now fully extend and reach 30cm in height. The drive as been changed, the single stage spur gears are just a headache and well... good hockey pucks :P The drive will use 5:1 planetary gearboxes paired up with brushless motors and have been moved to the front wheels so the internal layout is more streamlined.

The HDPE chassis is basically a 6 wheeled version of CSB 1's chassis. I realised how simple it would be to make once I stopped overthinking it. This also means the build should be cheaper as all the HDPE stuff can be done by me, plus most of the internals can be reused in CSB 2.1 as the only (planned) change is the drive motors.
