BUG BOT OVERVIEW
Download the Bug Bot Assignment
In the last unit, we created a surveying satellite to get a look at what the Martian landing surface looked like. If all went well, you and your team should have a group of maps of the area, and a plan for where you want to pilot your rover. You now get to work with your team to plan a rover mission. In this unit you should be learning:
- How to plan and program a remote rover
- How to plan and map out rover commands and pathways
- How to pilot a rover remotely
In the end, you’ll need to be able to use your team’s rover to remotely explore the landing site for the Malemute Mars Mission. As you develop your remote rover solution, you’ll go through three major steps:
- STEP 1: Learn about other rovers and their development
- STEP 2: Build, program, and test your remote rover
- STEP 3: Plan your rover’s navigation and route, then pilot your rover on the Martian surface
When you’re all done, you will have learned about rovers used by NASA to explore the surface of the moon and Mars. You also will have helped design, build, and program a rover and use it to explore a landing site for the Malemute Mars Mission.
PART 1: REMOTE ROVERS
(10 pts) About 2 days
For decades, NASA and other space organizations have sent satellites and rovers to the moon and other planets to learn more about them. As we start this unit, we’ll take some time to become familiar with those efforts and how rovers have evolved.
PART 2: DESIGN, BUILD & PROGRAM
(30 pts) About 3 days
Your team now has to build a small rover that can be easily driven on the Martian surface to identify and collect samples before the Malemute Mars Mission can send its crew. Your rover needs to be small and reliable so that it can be sent to the Martian surface and piloted from here on Earth.
PART 3: REMOTE ROVING
(30 pts) About 4 days
Finally, you and your team need to plan out the route for your rover’s traverse. Your rover will only have a limited functional lifetime on the planet surface, and you’ll need to balance that with the communication delay between Earth and Mars. Careful planning can lead to a great exploration of the surface!

Part 1: Remote RoversInvestigating the development of lunar and Mars rovers
To get started with unmanned systems, we need to begin by learning about the kinds of unmanned vessels used in space. We’ll start with a quick look at remote surveying satellites both on Earth and in other places in space. Then we’ll look at rovers of different kinds to think about how groups like NASA needed to design them in order to accomplish specific tasks.
You’ll also be asked to identify an Unmanned System that interests you and do some research to find out how it was made and how it is used. These ideas together will give us a good perspective as we start designing our own remote satellites.

- Mr. Benshoof’s Confirmation
Here’s what’s due in Part 1: Remote Rovers
- Take a full page of careful notes on lunar and Mars rovers
- Complete your own Rover Investigation
- Have Mr. Benshoof confirm your notes & investigation
Part 2: Design, Build & ProgramDesign, build, and program your rover
As our Malemute Mars Mission continues into Phase 4, our job is to design, build, and program a rover. This rover will be sent to the Martian surface that your team was able to map with your satellite. The job of your rover will then be to navigate the surface of Mars to identify water samples, magnetic ore, and clear the landing site.
Your job as a team here is to build your rover using your chosen system (VEX, FTC, etc) so that it can be driven remotely. You’ll need to add attachments for sampling water, collecting ore, and cleaning the landing site. You’ll also need to be able to receive a video feed so you know what your rover is doing!
GRADING & PROCESS
Discuss the problem with your team and clearly define your design brief in your engineering notebook
Design your rover following the given parameters
Build your rover following the design plan you and your team made
Program your rover to collect the necessary data – be sure to test your design to make sure it works as needed!
Have Mr. Benshoof review your design before it blasts off for Mars
What’s Due In Part 2: Design, Build & Program
- Design Brief
- Rover Design
- Rover Build
- Rover Program
- Mr. Benshoof’s Review
Here’s what’s due in Part 2: Design, Build & Program
- Create a design brief in your engineering notebook
- Design your rover
- Build your rover
- Program your rover
- Have Mr. Benshoof review your satellite before firing it into space
Part 3: Remote RovingDrive your rover on the Martian surface to accomplish tasks
Rover Challenge Overview
With your rover built and shipped off to the red planet, it’s time to plan your mission. Your rover will only be able to power for a short time every day, and even then only for three days before its systems are degraded. In addition to this challenge, communications with Mars take time, so your commands to the rover will have a significant delay before they lead to action.
For this final part, you and your team need to use your topographic maps to carefully plan out your rover’s journey around the planet. You’ll need to have a good plan to make the most of the short time you’ll have for your rover to operate. While there, your rover needs to sample as many water sources as possible, collect as many magnetic ore samples as possible, and clear your intended Mars Mission Landing Zone!
GRADING & PROCESS
Plan your rover’s journey around the Martian landscape carefully; include a map and diagram in your engineering notebook

Double Check: Unit ExpectationsCheck what you need to have completed by the unit deadline
The purpose of this unit is to give us some experience with the concept of designing something to drive remotely on another planet. While the concept is simple, the constraints get more and more stringent and challenging as we travel other places. This unit is meant to make us tackle problems of rover size and weight, control, planning, and navigation. This is not meant to be an easy challenge, but rather one that requires a lot of trouble-shooting, communication, and persistence. In addition to having the experience for ourselves, this unit should also put the job of NASA engineers in perspective as they try to send large rovers to Mars and beyond.
