upgrade to Kryten's articulating stomach

rv8flyboy's picture

When i built my robot, i liked the idea of an articulating stomach designed by Bob Houston, found as thingiverse thing:1409964.

Bob made a very nice design, but I never felt at ease with using just the 180 degree turn servos and the plastic spindles. They have a rather course pitch and can cause the robot to lean at random , for example when moving an arm.

Odd Job - BoozeBot MkII

For those too young to have seen the James bond movie Goldfinger - meet Odd Job, the evil henchman.

His hat had a deadly, razor sharp blade in the brim. This was one frisbee you did not want to catch.

FiniteStateMachine Service


A Finite State Machine, or FSM, is a computation model that can represent and control execution flow. Finite State Machines can be used to model problems in many fields, including mathematics, artificial intelligence, games or linguistics.

Example for develop:


NeoPixels and Ultrasonic sensors working together

Ray.Edgley's picture
For a long time you could not run ultrasonic sensors on the same Arduino as the NeoPixels.
This was because the sleep function in the Arduino would upset the NeoPixel communication control.
In the recent versions of MyRobotLab Nixie version, this issue has now been solved.
What you are seeing here is 23 NeoPixels running with 2 active UltraSonic sensors and a Passive Infra Red sensor all on the same Arduino Nano running under MRL control.


Who said you can't run YOLO on a Raspi

Testing Freds new program on the Nixie build 1.1.429.



Good news is it's working :-)

While I was in there, I started OpenCV, loaded the PyramidDown Filter and the Flip filter.

Bno055 Service


Intelligent 9-axis absolute orientation sensor

The BNO055 is a System in Package (SiP), integrating a triaxial 14-bit accelerometer, a triaxial 16-bit gyroscope with a range of ±2000 degrees per second, a triaxial geomagnetic sensor and a 32-bit cortex M0+ microcontroller running Bosch Sensortec sensor fusion software, in a single package.
