  • Motor controller, battery pack, charger and BotBoarduino microcontroller
  • Assembly required

The Lynxmotion A4WD3 Rugged Tracked Rover Autonomous 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 includes four sets of sprockets and a pair of reinforced continuous rubber tracks as well all the electronics needed for controlling the robot using an Arduino-compatible microcontroller, the BotBoarduino. Tracks offer incredible traction and weight distribution on a variety of surfaces and give the rover 63 mm (~2.48 inch) of ground clearance which allows it to be used effectively over brush, forest floor, paved and unpaved roads, on sand, over snow and mud, in urban environments and more.

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 12 V DC motors coupled to 27:1 all metal planetary gears. The rear shaft of each motor is equipped with a magnetic encoder that provides 12 pulses per revolution (PPR). The rover can reach a top speed of around 3m/s (120 in/s) without a 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 LED lights for increased visibility (Lynxmotion - A4WD3 Red Brake & White High Power LED Module ).
