Description
- Lynxmotion - A4WD3 Rugged Mecanum Rover Autonomous Kit
- Mecanum driven, microcontroller controlled mobile rover
- Incorporates seals for water & dust resistance
- Propulsion uses four planetary gear motors and 152mm Mecanum wheels
- Motor controllers, battery pack, charger and BotBoarduino microcontroller
- Assembly required
The Lynxmotion A4WD3 Rugged Mecanum Rover is a general purpose mobile robotic platform. The frame is used in three configurations: 4WD; Mecanum & Tracked, and variations of each platform include without electronics (so designers can integrate their own parts); an RC version and a microcontroller-based version for autonomous or semi-autonomous development.
This variation includes a full set of four 152mm diameter Mecanum wheels (two left and two right) as well all the electronics needed for controlling the robot using an Arduino-compatible microcontroller, the BotBoarduino. Mecanum wheels which offer unparalleled motion on flat surfaces, allowing not only for the full range of movement provided by 4WD, but also the ability to move side to side and more. These mecanum wheels are intended to be used on flat surfaces.
The machined aluminum frame integrates seals around each motor shaft, as well as solid rubber cord between the frame and all panel openings, making it dust and water resistant. A large marine inspection hatch on the top panel provides easy access to internal parts as well as being able to quickly swap or recharge batteries. Aside from the internal electronics mounting plate, the platform is symmetric and can be inverted.
The rover uses four powerful 12V DC motors coupled to 51:1 all metal planetary gears. The rear shaft of each motor is equipped with a magnetic encoder which provides 12 pulses per revolution (PPR).
Access panels are made of G10 composite and are intended to allow users to machine openings to add their own components. Included are also transparent polycarbonate panels which allow for an internally mounted camera and/or or LED lights for increased visibility (Lynxmotion - A4WD3 Red Brake & White High Power LED Module ).
Note: Be sure to install each pair of Mecanum wheels correctly. Intended for indoor use only.
