Coleman Benson 18.2 11 The Lynxmotion A4WD3 Mecanum Rover is a general purpose mobile robotic platform intended to be used in RC control or microcontroller-based for autonomous or semi-autonomous use. Each wheel is controlled independently to allow the robot to move in any 2D direction (i.e. omnidirectional drive). The wheels are large enough to be able to travel over bumps and obstacles, but the system is most suitable for flat surfaces, and it is best to avoid debris falling between the rollers.

Eric Nantel 6.1 15 The machined aluminum frame integrates rotary 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.

Coleman Benson 19.1 17 The rover includes four powerful 12V 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). These motors provide 4WD and allow the 4WD variation to reach a top speed of around 3m/s (120”/s) without payload. Unlike the 4WD and tracked variations of the A4WD3, the Mecanum rover requires two dual channel motor controllers.

19 Front and rear access panels are made of G10 composite and are intended to allow users to machine openings to add their own components, which may include a wired tether for power and control, LED or LCD feedback, a handle, or whatever else their application may need. Included are a pair of transparent polycarbonate panels which allow for an internally mounted camera and/or or LED lights for increased visibility. Additional panels are available separately.
