Based off NASA’s Opportunity, our rover gathers and displays light information from the environment as it drives. It is also controlled wirelessly with a household remote control!
In order to put the rover to work, you need to build a data collecting circuit and a wireless drive shaft.
The drive shaft is made up of two parts:
The data collection unit is made up of two parts:
Complete the circuit with two wires, the power module, and a 9V battery.
You can activate the drive shaft with any common remote control that uses infrared light to send signals. Power it up and you’re on your way to exploring the planet’s surface (a.k.a. the kitchen floor). As the rover travels, the number module display will rise or fall based on the amount of light hitting the sensor.
NASA engineers send instructions to the rovers via radio communications. Depending on where the planets are in their orbits, a radio signal traveling at the speed of light will arrive on Mars between just over 3 minutes or as long as 20 minutes. Your remote control signal should get to its destination much faster.
Create the body of the rover using your favorite building materials. You can replicate Opportunity or use one of NASA’s other rovers for inspiration. If you’d rather use household craft supplies, we have instructions for a simpler version of the rover on our website.
