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 until summer of 2017 - approximately 8 months.”

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 four-legged robot, a level builder, user-scripting interface in Lua, 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 four 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 price of Xemo will be discounted from the full release version. During the development, we plan to raise the price as new content and game play are added.”

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 1.3 Update - New Robots Added

Xemo is excited to introduce 3 new robots! The new robots are 4 legged with varying degrees of freedom. Sami, the simplest robot has four 1Dof joints. Buster, has 2Dof joints for each leg, plus a center body hinge joint to turn the body. Fido, looks somewhat like a walking piano bench, has 12 DoF total.

You can shape movements for each of these new robots using the same motion editor and then test them out on the challenge floor. The new robots are easier to balance and get walking. Xemo, the biped, is still there to challenge your motion creating skills.

We've also replaced the Sequencer with a Hotkey motion list. You can assign motions to hot keys and play them back during the challenges interactively.

Included are some minor bug fixes to robot motion and the display of the joint centers. We've also revised the UI to make things simpler to use. The Player's Guide (a PDF) explains some of the changes to the new UI.

Have fun and let us know what you think! You can provide direct feedback to the developers in game (we added a feedback button) or send us email at robots@xemory.com

Xemo Update for the Holiday Break

Xemo Early Access v1.1 Build 32

Version 1.1 of Xemo was uploaded today, Dec 23 2016 at 2:30 pm EST (7:30 pm UTC).

Here are the list of features added to Xemo:

  • Game level 5 is new.
  • All game levels now have leader boards.
  • We added a video recorder in-game. This captures video of the robot and writes out to a video file.
  • New tutorials for the balance controller and the robot sequencer were added.
  • Robot Sequencer: now you can specify how many times each motion should cycle.
  • Gravity well - we added the ability to rotate the robot around the vertical access.
  • Sound: Added sound effects and a sound settings panel.
  • Motions: We added a motion template named "BackSpring"

We will be updating Xemo once every month (around the 20th of the month) during Early Access. Please send us your feedback by posting here, or sending email to robots@xemory.com. The Dev team reads and welcomes all helpful feedback.

“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!”

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.

This simulation game Includes:

  • The Xemo robot - with 13 joints with a total of 24 DoF (Degrees of freedom)
  • Integrated rigid-body physics simulation
  • The Robot Lab where you create new robot motions
  • The Challenge Floor where you compete with your robot
  • The Pattern Editor, which you use to edit 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
  • The Balance Controller, used to add automatic 1-foot balancing control
  • Environment and machine sound effects
  • Leader boards - one per level
  • Quadruped (four legged) robots

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:

  • Motion sharing through the Xemo game server
  • Motion Sequencer finite state machine that lets the player create complex motion sensing and control
  • Ghost recording and sharing (allow in-game playback of other player's motion recordings)
  • More challenge levels (added each month)
  • Evolution engine for evolving complex robot motion behaviors
  • Learning Guides for classroom use
  • Xemo.tv public website for playback of the best robot moves created by the community
  • Player Scripting (Lua/Moon#) 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!
