  • Lynxmotion - A4WD3 Rugged Wheeled Rover Kit
  • 4WD Mobile rover platform for remote controlled / autonomous robotics
  • Rugged frame incorporates seals for water & dust resistance
  • Includes four planetary gear motors with integrated magnetic encoders
  • Requires assembly and additional parts

The Lynxmotion A4WD3 Wheeled Rugged Rover Kit 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 developers can integrate their own parts); an RC version and microcontroller-based for autonomous or semi-autonomous use.

This variation of the rover includes four 160mm diameter off road wheels and it is left to the user to purchase additional electronics separately. The beadlock wheels provide dampening and are a good choice when the robot will be traveling over flat or uneven terrain. These wheels provide a respectable 41 mm of ground clearance.

The machined aluminum frame integrates seals around each motor shaft, and 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 12 V DC motors coupled to 27:1 all metal planetary gears. The rear shaft of each motor has a magnetic encoder which provides 12 pulses per revolution (PPR). These motors provide 4WD and allow the rover to reach a top speed of around 3 m/s (120 inches per second) without payload.

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 ).
