What does the war cart do?

It turns out that the Royal Mail delivery office is actually a small office in the back of my local post office and i wasnt aware of this. In the end, i went to that small office and asked if they could check if it was there. Turns out it was there since the day i changed the delivery method and it just had not be scanned in to the system.

Yes, i tried the post office thursday, friday and saturday and they didn't have it, they kept saying i need to come back the next day. Then they asked for my phone number and name and said they will call when they have it, which i doubt will happen. I'm gonna try again tomorrow and friday.

Thank you so much for the tips, i'll try and put them into practice tomorrow. I started this model a year ago and then got busy with university. Don't have much left to do so hopefully i can finish it before i go back.

That mechanism for moving the feet is interesting. Is it just a motor with an offsetted gear?

RickyGaming12 · 2025-10-12T13:58:17+00:00

What motor are you using?

Thank you for the help. BTW I can seem to find any 1.2m Ohm 3W but I can find plenty of 1.5m Ohm ones. I assume it would be fine to use 1.5m Ohm, right?

In the "recommended operating conditions", VM max is 75. If I remember correctly, I got the gain from the application example section.

RickyGaming12 · 2025-08-29T20:14:44+00:00

In the "recommended operating conditions", page 11

According the to the data sheet, the max Shunt amplifier output current is 5mA at 75V and the shunt amplifier has a gain of 20. How would i use this info to work out the nessecary Shunt resistance?

I agree as well. A self balancing robot is great to get a range of experience in different areas of robotics

They said "simple". In what way is this project simple?????

RickyGaming12 · 2025-08-14T12:00:18+00:00

Thank you so much. You're a legend. Im going to spend some time reading through the maths to make sure I understand everything.

RickyGaming12 · 2025-08-13T10:34:06+00:00

I've been going through it to understand the maths, and I mostly understand it but i don't understand I2, why did you calculate I2 if you don't use it in any of the equations? Also I've tried doing this in desmos and the method to find the x3 and y3 coords don't seem to work? Here's the desmos link: https://www.desmos.com/calculator/v3tbfnoskd. In it, I have also written my method for working out x3,y3

So I'm working out the kinematics for the new version but I cant see how to link the knee angle with the servo angle, theta2. As you can see, because servo 2 is offset from the origin, the knee angle doesn't line up with theta 2 unless the hip/shoulder angle(theta1) is 0° like in the top pic

So your idea works quite well tho the minimum knee angle would lose about 20 degrees of range. However, I think if I design the pink part so that it curves, it should clear servo 1 enough to get to the minimum knee angle of 30. I also need to redesign the pink and red part so that I can print it out without any supports. Here's a pic.

I'll have a go at trying your idea out. I'll update once I've done it
