The Lynxmotion A4WD3 Rugged Rover Frame Kit is a general purpose four wheel drive frame which allows a user to add hubs, wheels, electronics, battery and accessories to create their own semi-custom mobile platform.

Lynxmotion - A4WD3 Rugged Rover Frame Kit - ISO

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 hatch on the top panel provides easy access to internal parts as well as providing the ability to quickly swap or recharge batteries. Aside from the internal electronics mounting plate, the platform is symmetric and can be inverted.

Lynxmotion - A4WD3 Rugged Rover Frame Kit - Hatch

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 which provides 12 pulses per revolution (PPR). The motor’s D-shaped output shaft is 8 mm in diameter, so choose appropriate hubs (sold separately).

Access panels are made of G10 composite and are intended to allow users to machine openings to add their own components. Four square transparent polycarbonate panels are also included which allow for an internally mounted camera and/or LED lights for increased visibility (Lynxmotion - A4WD3 Red Brake & White High Power LED Module ).
