AWS DeepRacer Evo and Sensor Kit now available for purchase
AWS DeepRacer is a fully autonomous 1/18th scale race car powered by reinforcement learning (RL) that gives machine learning (ML) developers of all skill levels the opportunity to learn and build their ML skills in a fun and competitive way. AWS DeepRacer Evo includes new features and capabilities to help you learn more about ML through the addition of sensors that enable object avoidance and head-to-head racing. Both are available on Amazon.com for shipping in the USA only.
What is AWS DeepRacer Evo?
AWS DeepRacer Evo is the next generation in autonomous racing. It comes fully equipped with stereo cameras and a LiDAR sensor to enable object avoidance and head-to-head racing, giving you everything you need to take your racing to the next level. These additional sensors allow for the car to handle more complex environments and take actions needed for new racing experiences. In object avoidance races, you use the sensors to detect and avoid obstacles placed on the track. In head-to-head, you race against another car on the same track and try to avoid it while still turning in the best lap time.
Forward-facing left and right cameras make up the stereo cameras, which help the car learn depth information in images. It can then use this information to sense and avoid objects it approaches on the track. The backward-facing LiDAR sensor detects objects behind and beside the car.
The AWS DeepRacer Evo car, available on Amazon.com, includes the original AWS DeepRacer car, an additional 4 megapixel camera module that forms stereo vision with the original camera, a scanning LiDAR, a shell that can fit both the stereo camera and LiDAR, and a few accessories and easy-to-use installation tools for a quick installation. If you already own an AWS DeepRacer car, you can upgrade your car to have the same capabilities as AWS DeepRacer Evo with the AWS DeepRacer Sensor Kit.

Getting started with AWS DeepRacer Evo
You can get your car ready to hit the track in five simple (and fun) steps. For full instructions, see Getting Started with AWS DeepRacer.
Step 1: Install the sensor kit
The first step is to set up the car by reconfiguring the sensors. The existing camera shifts to one side to allow room for the second camera to create a stereo configuration, and the LiDAR is mounted on a bracket above the battery and connects via USB between the two cameras.
Step 2: Connect and test drive
Connect any device to the same Wi-Fi network as your AWS DeepRacer car and navigate to its IP address in your browser. After you upgrade to the latest software version, use the device console to take a test drive.
Step 3: Train a model
Now it’s time to get hands-on with ML by training an RL model on the AWS DeepRacer console. To create a model using the new AWS DeepRacer Evo sensors, select the appropriate sensor configuration in Your Garage, train and evaluate the model, clone, and iterate to improve the model’s performance.
Step 4: Load the model onto the device
You can download the model for the vehicle from the AWS DeepRacer console to your local computer, and then upload it to the AWS DeepRacer vehicle using the file you chose in the Models section on the AWS DeepRacer console.
Step 5: Start racing
Now the rubber hits the road! In the Control vehicle page on the device console, you can select autonomous driving, choose the model you want to race with, make adjustments, and choose Start vehicle to shift into gear!
Building a DIY track
Now you’re ready to race, and every race car needs a race track! For a fun activity, you can build a track for your AWS DeepRacer Evo at home.
- Lay down tape on one border of a straight line (your length varies depending on available space).
- Measure a width of approximately 24”, excluding the tape borders.
- Lay down a parallel line and match the length.
- Place the vehicle at one edge of the track and get ready to race!
After you build your track, you can train your model on the console and start racing. Try more challenging races by placing objects (such as a box or toy) on the track and moving them around.
For more information about building tracks, see AWS DeepRacer Track Design Templates.
When you have the basics down for racing the car, you can spend more time improving and getting around the track with greater success.
Optimizing racing performance
Whether you want to go faster, round corners more smoothly, or stop or start faster, model optimization is the key to success in object avoidance and head-to-head racing. You can also experiment with new strategies:
- Defensive driver – Your car is penalized whenever its position is within a certain range to any other object
- Blocker – When your car detects a car behind it, it’s incentivized to stay in the same lane to prevent passing
The level of training complexity and time also impact the behavior of the car in different situations. Variables like the number of botcars on the training track, whether botcars are static or moving, and how often they change lanes all affect the model’s performance. There is so much more you can do to train your model and have lots of fun!
Join the race to win glory and prizes!
There are plenty of chances to compete against your fellow racers right now! Submit your model to compete in the AWS DeepRacer Virtual Circuit and try out object avoidance and head-to-head racing. Throughout the 2020 season, the number of objects and bots on the track increases, requiring you to optimize your use of sensors to top the leaderboard. Hundreds of developers have extended their ML journey by competing in object avoidance and head-to-head Virtual Circuit races in 2020 so far.
