Engineers redesigned the Mars 2020 Perseverance rover's wheels to be more robust, due to wear and tear the Curiosity rover wheels endured while driving over sharp, pointy rocks. Perseverance's wheels are narrower, with a bigger diameter and thicker aluminum. Perseverance has six wheels, each with its own motor. The two front and two rear wheels also have individual steering motors, to turn in place a full 360 degrees. The four-wheel steering also lets the rover swerve and curve, making arcing turns.
Tech Specs - Wheels
- Materials: Made of aluminum, with cleats for traction and curved titanium spokes for springy support.
- Size: 20.7 inches (52.5 centimeters) in diameter
- Other: One full turn of the wheels with no slippage drives the rover 65 inches (1.65 meters). It has a clearance of two feet, can go over obstacles of up to 40 centimeters & slopes of up to 30 degrees with a top speed of 0.1 mile per hour.
