The Tumbleweed rover V3 gets its characteristic shape from its numerous arcs, creating the 5-meter-diameter-sphere. Its six tetrahedrally arranged sails ensure optimal air-resistance and maximize the Tumbleweeds’ area of coverage. On these sails, solar cells harness the Sun’s power for the rover’s electronics while additionally charging a battery for night-time operations. The Tumbleweed rover gathers data using a wide array of sensors such as barometers and hygrometers, as well as high-resolution cameras. These can be integrated into the rover’s payload bays. Further features include a collapse mechanism for transport to Mars as well as omnidirectional antennas for communication.
