Versions
- The MiMi will iterate through different marked versions:
- Dev Kit: Development Kit of Boards, Cables, and Sensors
- M0: Head with Sensors
- M1: MiMi on (self balancing) Wheels or Tracks
- M2: MiMi Bipedal
Size
The MiMi would ideally be between 18” and 32” (46cm and 81cm) in height—such as a small walking toddler or a large toy—and would be as light as possible while not diminishing quality, stability, and strength (factoring in the anticipated weight of the batteries). A simple goal is to ‘fetch me a can of soda’ and have the Operator of the MiMi able to retrieve a can.
Function
The MiMi will be equipped with onboard capabilities for walk, run, strafe, jump, crouch, stand up (when fallen), stop. With additional actions able to be added as plugins: climb stairs, dance, flip, slide, kick, etc.
Skinning
The OP will have an avatar that upon entering the MiMi and taking control will be applied to the various configurable panels, actions, LEDs, and animations.
Parts
The MiMi should utilize known working configurations and parts, WiFi, BT, Cellular, SIM card, Antenna, Battery (possibly weighted into the mechanical design of the humanoid shape), LEDs, sensors (lots of sensors), GPS, accelerometer, proximity, night vision, cameras (for eyes), microphone (ears), speaker (mouth), gyroscope, motors (servos), grip like capabilities for feet and hands.
Expressions
The MiMi should be able to physical show the 7 universal expressions: Happy, Sad, Angry, Scared, Disgusted, Surprised, Contemptuous, that should be controlled by the LED eyes and diffused LEDs into facial panels and colors.
Eyes
The eyes should be the most expressive part the MiMi. With protective glass and cameras integrated. The eyes should be able to offer a wide range of customization and emotions.

Image Stabilization
The MiMi will operate in physical space, therefore the OP will be seeing through the camera eyes of the MiMi, when moving this will likely create immense shaking that would not feel natural to the OP. Image stabilization will likely be a requirement so walking, strafing, jumping, running, crouching, head tilt all are smoothed out to appear more to the OP as if they are physically there looking with their own eyes and moving with their own bodies.
LED Username Display
The MiMi will need to have an LED to display the username that is operating the MiMi. This will allow a very easy spot-check that the MiMi is being operated by a known approved user. The location should be easily readable from the owner, such as the back of the head or shoulders and should support a display or scrolling display to handle 32 or more characters easily. The owner should be able to quickly look at the LED username and feel confident that the operator authenticated against that username.
Hardware Kill Switches
The MiMi will have hardware kill switches (HKS) for:
- Cameras, microphone, and speakers.
- All Radio Frequency (RF) chips, Cellular, WiFi, BlueTooth, etc.
- Physical power switch. This will ensure that the owner has full control with physical easy-to-use switches disabling power at the hardware level.
Registered Operator Required
The MiMi will require a registered and authorized operator (OP) to remotely control the MiMi.
Subscription by Default
The MiMi will by default have a paid for subscription to utilize the OP App to connect to the MiMi. The local owner will have the option to self-host or operate the MiMi without a paid subscription.
Cellular Subscription by Default
The MiMi will include by default a Cellular subscription bundled with the OP App subscription, even though the MiMi can connect via WiFi for OP App use. The local owner will also have the option to do WiFi only or utilize their own prepaid SIM to operate the MiMi outside the default cellular subscription.
Charging MiMi Battery
The MiMi will have a battery level indicator near the heart panel—desiring a pulsing heart LED icon.
Operator and Owner Administration
An operator (OP) and owner must register for an account to operate a MiMi. There will be an option to self-host but would be the exception to the default.
- Domain:
A to-be-announced Purism managed domain will be utilized for username registrations.
- Usernames:
Lowest common denominator username required (same policy used for librem.one usernames). Account names cannot be reused, avoiding identity abuse. A canceled account deletes all data and that account name is gone forever. A lost password without a recovery address is gone forever. The OP username is what appears on the LED on the MiMi after connection.
- Logging:
All account uses are logged for future accountability. All MiMi operator connections are recorded for verifying operators to usage. Any MiMi logs or recordings should be kept locally on the MiMi itself where the owner owns the logs and access to them.
Owner MiMi Setup
The MiMi owner must complete the initial setup to manage the MiMi properly.
- Registration:
The owner will register the MiMi to verify an active subscription and account.
- Permission:
The MiMi defaults to deny all access. The owner must allow a specific username (opt-in) to access the MiMi. Username’s are shared with the owner out-of-band (a OP friend could text message their username to allow the owner to enable that username). Having a local only access to register the MiMi and manage the OPs that can access it would strengthen security for owner management (e.g. no remote OP permissions granted, only a local network or WiFi direct admin connection would be allowed). Alerts upon MiMi access would be shared to the owner.
