Description

The idea is to create a remotely controlled rock crawler, based on an 8x8 chassis for shits & giggles

Planned Featureset

  • 8x8 drivetrain
  • 3 steerable axles
  • remotely lockable differentials
  • remotely switchable hi-lo gearbox
  • double-wishbone individual suspension
  • pan/tilt FPV camera

Drivetrain

The following drivetrain will be configured: Drivetrain-layout.svg

Motor

TBD; This will need to be a motor with a high amount of windings so that it will generate a lot of torque with a low RPM. This likely limits the choice to brushed motors.

Gearbox

Since I want to be able to have multiple gears, some gearbox needs to be built. For this, the following layout has been designed Gearbox-layout.svg How this works: The motor will drive the motor gear. This gear drives the first reduction gear, and the axle of this reduction gear drives the gearbox. Using a servo, both LO and HI gearing can be chosen.
