VEX is proud to release the Build Instructions for the 2025-2026 VEX V5 Robotics Competition Hero Bot, Dex, designed to play the 2025-2026 VEX V5 Robotics Competition Game, Push Back.
Build Instructions can be found at builds.vex.com
We will be releasing Video Walkthroughs, similar to previous years, in the coming weeks.
Thank you for your patience during the delay for this release. Our sincerest apologies, again.
where’d the drive gearing go, it’s just 1 gear now
This doesn’t matter much, but is the bot in this picture built slightly incorrectly? The traction wheels are in the front, when, in the instructions, they’re in the back. Obviously this doesn’t matter much performance wise, just wanted to mention it.
Thank you so much @bkahl .
We have started building it and noticed that there are some parts required for the hero bot that are not part of the Competition super kit.
Specifically, Steps 94 and 124 require U Channels
and step 166 the 90 degree gusset plate looks different from the one in the competition kit.
I noticed this too, but just to let you know I would recommend using the wheels as shown in the instructions as this guarantees that when pushed from the side the side you are scoring with at the goals will resist movement.
What is the size of the traction wheels in the front? This seems smaller than the traction wheels in the super kit
Correct me if Im wrong but the photo I attached looks like the gear ratio its just hidden a little In the back
It does, but when looking through the online build instructions, it is not there.
The GDC has alead commmented on this topic saying which explains the changes in the gearing of the robot:
It does look like that, but this photo was likely taken before the release of the instructions. They probably changed it so it is a direct drive after this photo.
May have been one of the parts they used too many of? They had to revise the build when they noticed it could not be built with only the parts in the kit.
Even so, there is no need for a gear next to the wheel. There is also an inconsistency with the type of wheels. In the top image, the traction wheels are in the front, but in the build instructions, they are in the back. This can’t be a case of “the parts aren’t in the kit,” because all they did was switch around the positions.
We don’t know what the revision process was or how they went about it, but I’m sure VEX has a reason for what they did.
You would definitely want to build with traction in the back, as those are the powered wheels. Traction in front would cause stuttering/skidding turns.
Yeah I was going to say that the traction/omni placement seems odd, since they are not connected. It will not turn well for sure.
