mumbles in build quality
(btw Ryan Liao’s YouTube channel and 9MotorGang’s Youtube channel have videos about build quality)
From what I can see… hook + ladybrown. The standard design for a decent robot (half-meta?). (I’m kinda making fun of it because I’ve recently had urges to build a High Stakes clawbot.) Is the drivetrain 200 RPM 72 tooth to 48 tooth (ending up as 300 RPM)? Have you checked to see if rings can travel unobstructed through an imaginary intake? (And, if the intake is hook, the C-channels are probably sticking out too much in the back, going past the tip of a (securely clamped) mobile goal.)
For the mobile goal clamp, a design I am interested in is KUdos’s clamp on Pits and Parts. There are two other designs I have in mind:
- Lever: just pneumatics pushing/pulling on a rotating piece of metal.
- Locking mechanism: where the motor/air cylinder can simply move as normal but, in doing that, makes a pivot bend back on itself, making it impossible to steal the mobile goal (without breaking the mechanism). I believe that if a motor is to be used on a clamp, it should be a locking clamp. (Is it possible to use a 5.5 W motor on the clamp?)
@99976D covered all of the basic stuff I can notice. One thing I’d like to say though: a good PTO is not going to be built in 2 weeks.
