Great video! Note that in the video description, it says Skystone instead of Ultimate Goal.

Where do you have your Control Hub and Expansion Hub mounted? My team was thinking of having an arm elevated above the ground and using a pyramid structure to support it (similar to your robot, although I don't think they pyramid supported it), and putting the hubs on the angled walls, which would obviously be bad since we need the gyro for autonomous.

We mounted the hubs vertically to the outside of the transfer walls. As seen 4:30 they are just above the drivetrain and outside the MDF walls.

@@Brainstormers8644 Thanks! Also, what material did you use for the angled walls? It looks really good, so since we're planning on a design that would have walls similar to that I'll suggest whatever material you used to my team.

It seems like you guys run belts in-channel for your drivetrain. Do you use the round-bore set-screw timing belt pulleys from actobotics? Did you ever face issues with the set screws loosening?

@Brainstormers8644 2 жыл бұрын

You are correct that we run belts in-channel for our drivetrain. We started the season using 3d-printed pulleys and clamping hubs. We then changed to gobilda 5mm HTD belts with 16 tooth pulleys. One pulley was the D-bore for the motors and the other was the 8mm REX Bore for the wheel axles.

@@Brainstormers8644 I see, thanks for the reply! Since Actobotics channels are imperial (inches), and the belts are metric, did you have to use any belt tensioners?

@theclueless11212 2 жыл бұрын

May I also ask how you fit Actobotics Clamping hubs inside of Actobotics U-channels? I just checked the tolerances, and there is less than 1mm of space from the hub hitting the inside of the channel, if you replace the screws on the clamping hubs with button-head screws.
