Some stuff I work on now
Low cost 6-axis robotic arm developed for education. Fully 3D printable, released for free use along with all the instructions, BOM etc. Made under Erasmus+ Eu program.
I did some experimenting and made a custom color resin for 3D printing. That is translucent amber printed enclosure for LoRa ESP32 dev board. To be experimented with.
Another experiment with gearboxes. Proof of concept of ring gearbox, single stage, high-reduction (1:40 or so in the video) non-backdriveable and hopefully almost no backlash. Can be mounted on the outside rim of BLDC outrunner. Better prototypes are being made, I will update that with relevant stuff if it turns out to work well.
