4WD Mantis™ robot chassis

A rover-like chassis for 4-wheeled robots

This 4-wheeled 4WD Mantis™ mini rover owes its robustness and strength to its Actobotics structural components. With its aluminium chassis, its 4 Revolver wheels and its off-road tyres, the 4WD Mantis™ is great for outdoor navigation, whatever the terrain. You’ll have plenty of torque to overcome any obstacle with smooth driving, especially as this outdoor robotics chassis can flatten itself entirely to hug the terrain.

Actobotics has thought of everything! Whether you plan to attach a GoPro, sensors or an IMU, Actobotics’ structural parts are robust enough to accommodate a great variety of modules (there are regular holes in the plates to mount them firmly).
