Your robot is close to how I did this comp the first time. My robot was a folding design as well only instead of a “M” shape, mine was a “L” shape. The problem I had was with balancing when over the gap, so I had to actuate everything on the robots frame to move backwards when starting the gap. Then to move forward when leaving the gap. Otherwise I kept falling in.
Your design is much better (and more stable) than what I did.
Now on to timing, you can see him turn it on at roughly 59 seconds, then its off the start table at 3:04
So we convert 3:04 to seconds
3 times 60 + 4 = an end time of 184 then subtract the start time of 59
Awesome stuff. Looks like you would have climbed up on the third video attempt if the launcher hadn’t got in the way. Maybe consider abandoning it after it fires the hook?
OK, here’s my even uglier entry to this challenge.
It doesn’t look very sophisticated but it does do the job.
A bit of explanation. It starts to lower the bridge using the nail file, as can be seen, then sets off across on its wheels, pushing the rest of the bridge down. When it reaches the black tape, using an LED and an LDR, it stops. The motor is then started to wind up the bridge behind it.
I’ve had to ask a relative on timing your video, as from the camera zoom, I can’t clearly see when the start side bridge lifts off the table. We had to use the glare in the window, and the angle of the bridge to judge this.
We both agreed within 1 second of both the start time and end time.
(drum roll)
We put the start time at 1.31 (first power switch on) and the end time at 2.23 (bridge angle).
52 second runtime (based on the limitations from the video)
Sorry about the camera work, I was watching the motor spindle winding in the thread, and forgot the other end of the bridge :o
I wondered if anyone would pick up on old “HR”. It’s an expression I heard a lot when I was growing up, but not used much nowadays. I thought it was quite apt for describing my “contraption”
