wall bot
- 6 Devlogs
- 10 Total hours
Robot that can draw on a whiteboard or wall using tethers and stepper motors.
First Working Moments before failure
The wall bot was successfully working and drew some very basic shapes like squares moments before the tether suddenly snapped and it succumed to the laws of physics. 🫠
The picture is of it working about half a second before it snapped
Things to do:
- Get stronger string
- Program a method to command the bot to any coordinate on the whiteboard rather than manually programming individual steps

Finished wiring (wire management was a pain as always)
Finished printing the whiteboard mounts for the string
Started programming!
Redesigned pen holder to hold the tip of the marker at the correct depth when deployed.
Things to do:
- Design spools
- Design corner mounts for the whiteboard to hold the string
- Program!
first assembly of the wall bot done in real life! Many modifications are needed, mostly regarding clearances, but the entire pen holder needs to be redesigned because it holds the pen to close to the bottom of the bot right now
finished the pen lifting mechanism, spools still need to be created
The main gantry is done except for the pen lifting mechanism. The spools for the rope still need to be designed as well as the mounts for the end of the rope.
