Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Xemo is ready for players to provide feedback on the creation of robot motions and game play in the early levels. We need your input to help shape the game challenges.”

Approximately how long will this game be in Early Access?

“Xemo will be in Early Access through the end of 2017.”

How is the full version planned to differ from the Early Access version?

“The full version will have additional game levels along with in-game access to the Xemo game server, which tracks the leader boards, shared user content, and game stats. In the full version, we plan to add a level builder and an evolution engine to refine motions such as walking or running.”

What is the current state of the Early Access version?

“Xemo currently runs on Mac and PC, and provides the full motion pattern editor, a sequence controller and 16 game levels. It is a playable game with refined graphics and sound.”

Will the game be priced differently during and after Early Access?

“The early access of Xemo will be free-to-play. We plan to introduce robot kit add-ons as paid DLC (downloadable content). Anyone who purchased the game prior to v1.6 will receive free robot kits of equivalent or greater value to their original purchase price.”

How are you planning on involving the Community in your development process?

“We invite all players to participate in our Xemo Community forum. The developers and designers will be actively responding to players feedback. Our plan is to update the Xemo version every month, adding new content and game play refinements. Players can review our roadmap in the Xemo forums and provide feedback on our plans.”

Xemo - Evolution Chamber Released! (v1.7)

Here are the new features in Xemo v 1.7. We've received an overwhelming response to Xemo after moving to Free-To-Play. Try out the new evolution engine. If you are having trouble getting started, check out our videos at https://www.vimeo.com/xemory. We also have in-game tutorials to help you out.

The New Stuff

Evolution Chamber - A new section of the game used to evolve robot motions. This is survival of the fittest, where the best robot is the one that gets closest to the target. The target is a moveable puck in the Evolution Chamber. Any of the four robots can be evolved. You set the number of generations, robots per generation to test, and the total test time. Choose a symmetry (left/right, front/back, diagonal or free) and start the evolution. It takes any where from 3 mins to an hour to evolve a motion, depending on the type of robot you use. You can change the time scale (5x is 5 times faster than real time) to evolve quickly. When you robot is ready, save your evolved motion with a name and assign a key to use in the game levels.

Leaderboards - Each game level has its own leaderboard based on time. The top ten score are shown.

Remember me - We added a feature to remember your login and password, which is encrypted.

Xemo Biped - Tthe balance controller has been restored, and now works correctly.

Tutorial Videos - The videos now display in-game rather than open your browser. The first level on each game level track has a video link.

Feedback button - Now includes your email or steam name automatically. The feedback email goes directly into our support system, viewed by our developers. We will respond to all feedback received (good or bad), so click away!

Xemo : Sixteen New Game Levels, Redesigned Robots, Improved User Interface

Xemo 1.6 Update - August 2017
We now bring you Xemo v1.6, a major overhaul of the user interface, robot designs and game levels. We have completely re-designed and replaced the game levels with 16 new levels - from mostly easy to more difficult. We've reworked the user interface, created better controls including keyboard mapping for motions. The game has been split into sections: the Robot Selection, the Motion Creation and the Level Play section. Have a look at the new screen shots - the game art and new robot designs are impressive!

FREE-TO-PLAY: Xemo is moving from paid to free-to-play. Not to worry if you paid for the game we'll take care of you. In the future, we'll be releasing robot parts kits and the Xemo Robot Builder - paid DLC for the game. All Steam players that purchased the game prior to August 1st, 2017 will get free access to the new DLC to match or exceed their game purchase. We thank you for your support and continued interest is seeing Xemo evolve.
(it may take us a day or two to convert from paid to Free-To-Play while we turn the crank on the Steam engine).

“Robots Podcast #220: Teach Xemo to Move”

“Time to bring my Toribash skills to a test! Xemo Robot Simulation is a neat simulator game where you can create movements for a robot! I went through some challenge levels where I had to get my robot to walk, run, turn, and even jump by manipulating its joints. Pretty cool!”
Ze Royal Viking

Free To Play in August 2017

In August 2017, Xemo will move to Free to Play. This will happen with the release of version 1.6. In the future, we'll introduce the Xemo Robot Builder and robot part kits as paid DLC. If you purchased the game prior to August 1st, you'll get equivalent credit in DLC when released.

Evolution Engine Added Sept 2017

For release 1.7, we've added the Evolution Chamber, which includes and evolution engine used to evolve your robots behavior. This is still experimental, so play around with it and let us know what you think. We will be adding penalty constraints to the fitness function along with ability to evolve the motion of a subset of robot joints. Lots more to come.

About This Game

Xemo is a physics-based simulation of a humanoid robot. Highly detailed graphics and a refined user interface allow you to quickly create new robot motions such as crouching, crawling, jumping, rolling, walking and climbing. Combine your motions in a control sequence to solve the game's challenging obstacle courses. Compete against your friends and rivals to move to the top of the leader board for each level. You are rewarded for sharing motions with the Xemo community, and can continue to improve your robot's performance using better, faster and more efficient motions. How fast and agile is your robot? Play Xemo and discover just how good you are.

We just added: (v1.7 Sept 2017)

  • The Balance Controller redesigned for bipedal robots.
  • Leader boards - one per level
  • Evolution engine for evolving complex robot motion behaviors

This simulation game already includes:

  • Xemo : a robot with 13 joints with a total of 24 DoF (Degrees of freedom)
  • Sami - a simple 4-legged robot that you teach to crawl, turn, walk, jump andturn over.
  • Buster - a more complex 4-legged robot that can walk something like an ant.
  • Fido - the dog-like robot that has hip and knee joints - a greater challenge!
  • Integrated rigid-body physics simulation
  • The Robot Lab where you create new robot motions
  • The Pattern Editor, which you use to creation motions for your robot.
  • The Game Levels (16) where you compete with your robot
  • The Gravity Well, to suspend and position the robot in mid-air
  • The Joint Editor, used to adjust the robots ankle, knee, hip, abs, shoulder, elbow and neck joints
  • The Spring Editor, used to set the speed and strength of each joint
  • Environment and machine sound effects

Early Access
Come and join us to help shape the future of Xemo! We need your help. This first version of the game includes the motion pattern editor, the motion sequencer, fully functional bipedal robot and four game challenge levels. Our plan is to release a new version every month over the next year, with these features planned:

Roadmap for Future Releases
  • Xemo Robot Builder - build your own robot designs from parts! (in development now!)
  • Robot Kits - pro designed robots that you can use in the game challenges.
  • Motion sharing through the Xemo game server
  • Ghost recording and sharing (allow in-game playback of other player's motion recordings)
  • Learning Guides for classroom use
  • Player Scripting (Lua/Javascript) interface through XemoAPI for direct robot control. VS Code debugger integration
  • Data capture, export and plotting of robot motion (joint trajectories, center of mass, rigid body position, acceleration, rotation)
  • Robot skins and colorization
  • Cool ideas for expansion from the community from players like you!
