DIY 2DOF Motion Simulator – Inspired by Mantis FS2

Hi everyone,

This is my first serious attempt at building a 2DOF motion simulator with electronics. In the past I experimented with a simple PVC frame build, but now I’m stepping up to something closer to the excellent F1 Style 2DOF Mantis Simulators FS2.

At the moment most of the parts are just starting to arrive. I’m still waiting for the motors and hall sensors, and I need to buy the power supply and some structural pieces. Once the motors are here I’ll start drawing and assembling the frame.

Planned hardware
• 2x 24V 440W 1:60 worm drive motors
• 2x BTS7960 43A H-Bridge Motor Driver (I'm also waiting for sabertooth driver for upgrade)
• Oubit 12-bit Hall sensors 360°
• Arduino Uno R3 (I think)
• 24V PSU (to be purchased)
• Aluminium frame, 40x40mm , almost identical to the Mantis FS2 design

Notes
• Being in Argentina makes sourcing parts more complicated, so progress may be slower.
• This is my first time working with electronics at this level, so I’ll be learning as I go.
• The goal is to replicate the Mantis FS2 style as closely as possible.

Closing
I’ll keep updating this thread as parts arrive and the build progresses. Any advice from the community on motor control, power supply choices, or hall sensor integration would be greatly appreciated.

For now, I’m still reading through the documentation available on the site, so I’m aware that most questions are already covered there.

I want to add the links to the items so you can see where I bought them, but I think I haven't enough posts yet to use this feature maybe (?), also with the link to mantis post
