LoCoRo Chassis Hardware
The basic LoCoRo chassis needs to secure the wheels or treads, the drive motors, and the electronics.
There are many options for the chassis.
hardware chassis options
  • The tricycle chassis use two drive wheels and a small free wheeling caster for the front. The system used differential drive - similar to how a zero-radius lawnmower drives. There are kits available with polycarbonate or metal frames and a DIY solution may be built with almost any parts available. Wheels can be purchased, cut out of available materials, or 3D printed. Wide plastic jar lids - like those from peanut butter jars - make great wheels.
  • The tank chassis use a left and right drive sprocket and treads. This system also uses differential drive. RC tank kits are available and a DIY solution may be built using small timing belts for treads. When using RC kits, the DC motors will require electronic speed controllers.
  • A customer chassis may be constructed from a wide range of materials. They may also be designed and 3D printed.
  • Chassis typically use an even number of drive motors with half used on the left and half used on the right. A differential drive system is the easiest to build.
  • A mecanum wheel system requires four drive motors - one per wheel. The mecanum wheel has rollers which are ±45 degrees to the wheel's axle. Two wheels have the rollers at +45 degrees and two wheels have the rollers at -45 degrees. Mecanum wheels allow the chassis to move like a tank and also to move laterally. Unlike the simple wheel, where each wheel is a single print, each mecanum wheel is a collection of printed parts and fabrication. More details on the printing and assembly are covered in the section on 3D printed parts.
