4WD Metal Robot Chassis Kit w/ Mecanum Wheels

Included in this set is an aluminum frame equipped with four motors and mecanum wheels. The frame offers sufficient space to incorporate sensors such as LiDAR or a camera for computer vision, as well as a computer like Raspberry Pi or Nvidia Jetson or an Arduino MCU and batteries.
Mecanum wheels prove highly beneficial in enhancing a robot’s maneuverability. These wheels possess rollers angled at 45º that move independently, enabling the robot to move in various directions: forward, backward, sideways, diagonally, or spin in place. It’s important to note that these wheels differ from omnidirectional wheels, although the end result is nearly identical. By manipulating the rotation of specific wheels, the robot can alter its heading or spin in place.
The motors come equipped with encoders. The inclusion of encoders allows for the addition of an IMU sensor and the creation of a room map. This facilitates the conversion of the chassis into an autonomous robot capable of navigating smoothly across surfaces in apartments, buildings, or factory floors.
Mecanum wheels do possess some drawbacks when compared to the “normal” wheels used in cars or shopping carts. These wheels have a tendency to sway from side to side when the robot attempts to traverse an inclined floor.

Mecanum wheels have a reputation for experiencing a decrease in grip.
