First test of the second instinct for Zakhar

Testing of the mind of Zakhar with two “instincts”: Error happened.

New test site!

Just finished a new site for tests and demonstrations! New place, new hardware, more updates soon! Error happened.

Unfortunately, I broke my ultrasound sensor during resoldering of connectors. Taking advantage of necessity of buying something, I’ve bought three new ones! Updated code with a new ultrasound sensor driver: https://github.com/an-dr/zakhar_sensors/tree/c4e7a5e5c91acbbc1efdaaa4122e46428793c973 Error happened.

Sensor Platform with STM32

Done! Now, sensor data is collected by a powerful STM32 MCU with FreeRTOS. This will help to add even more sensors. For now, there are two: Here is a video of the update in action: Links: Photos bellow. Error happened.

Calm prototyping evening

It’s a good night to move the sensor platform to a new MCU and add some sensors to demonstrate working of the emotional core (roadmap). PR for the update (WIP): https://github.com/an-dr/zakhar_sensors/pull/4 Error happened.

Emotional Core: temp impacts + refactoring

Just finished a huge update for the Core. The new feature is “temporary impacts”. It simulates a situation, that you can get watching a screamer (Caution! ). Something scarry is happening, you are getting a lot of adrenaline and cortisol, after 5…

Zakhar Milestone: Zakharos

Changelog since the Reptile Demo Milestone: Common: Sensor platform: Computing (brain) platform: Moving platform: Repository: https://github.com/an-dr/zakhar Error happened.

[Bad Idea, canceled] Power post. Part one.

There are a lot of issues when you connect low- and high-current devices to the same electrical circuit. Basically, you are getting: That’s really annoying that’s why I spend last several weeks thinking how to implement power supply for Zakhar.…

Turns: -45, +45, -90, +90 degrees

Updated code here: https://github.com/an-dr/zakhar_platform/pull/2 Error happened.

Assembled with the new moving platform! Turn 90 degree

From the Raspberry, the moving platform gets an argument 0x5a (90) degrees, then a command to turn right. If the argument is 0x00 command is executing during 100ms then the platform stops. Error happened.
