USBQuadStep USB host board for 4 TMC2209 stepper driver modules

For the Amsterdam North-South metro line station at Amsterdam Central we designed a custom sieve, sort and select installation allowing untrained archaeologists to continuously retrieve artifacts during the sinking of the station caissons.

ESC designed for driving two BLDC motors per board, up to 32A per channel and 2x 15A indefinitely (reliably). The in-phase shunt resistors allow FOC, a feature not present in drone ESCs. Hall sensors are also supported. The control interface is 12Mbps USB for more flexible control and telemetry, in…

The Road So Far

The rise of robotics and AI is often described as a risk to labour. But is it really?

Write-up on configuring an ODrive v3.6 brushless motor controller to drive two sensor-less motors from a battery. From unboxing to first runs, adding some notes and experiences to the startup guide.

Robotic, fully automated, stone cutting installation for creating prefab cut-to-size basalt chunks and sand-lime blocks for prefabricated construction elements.

The Wall-R wall and window washing robot is a cable-bot for autonomous building maintenance. It can inspect and wash an entire hotel facade for a fraction of the costs and risks of traditional window-washing services.
