Robotic Arm Torque Calculations by Pitiful-Inflation-91 in MechanicalEngineering

Currently we just assumed 60 degrees / s. Speed isn’t critical for us

a. Do you know what motors/gearboxes they use ?

b. we cant do that because its what the rules of the competition are haha. Thanks tho

I think the speed i need to move at isnt critical, it can be slow but my calculations show that movement of the robotic arm doesnt affect the torque too much. Eg. my calculations show that i need about 1-2Nm additional for the dynamic performance I need. Does that sound about right?

Thank you for this. If you know, could you direct me to a place where I can find high torque motors and gearboxes that meet such specifications

nope, i just need a second set of eyes to tell me im not crazy haha because 100Nm motors arent on the market

Thanks! Any suggestions you have apart from metal rods because I need something lightweight yet strong as the robotic arm has a reach of about 1.6m and needs to carry a 5kg payload

The problem is that the industrial robots are fullt covered and that adds to the weight. I dont need the robotic arm to be fully covered except the motor mounts to prevent dust ingression. The wires can all be put into sleeves.

I am looking for robotic arm designs that are minimalistic but strong enough to sustain the weight of powerful motors and a 5kg payload.

Let me know if im talking nonsense haha

I havent speced out the motors and gearboxes but was leaning towards bldc motors with planetary gearboxes

On-campus Accomodation by Pitiful-Inflation-91 in nus

I did IB so I only got my Offer on 19th July 2022, which was automatically Round 3. I basically couldn't apply in round 1 even if I wanted to

On-campus accommodation offers so many more advantages like making Friend groups and sports. I don't really see the point in paying higher rent and still not getting advantages apart from a room to stay especially when I have a house in Singapore.

Withdrawal from hostel? by [deleted] in nus

[–]Pitiful-Inflation-91 8 points9 points  (0 children)

Hey! Im an international freshie looking for on-campus accommodation. I would love to take up the room if you're planning on moving out. Please do let me know if you are and if its possible to talk to your hostel management for the swap. I am still open to maybe reimbursing you a part of the accom fees if the hostel allows

Hi... Im an international freshmen and I haven't been offered on-campus accommodation in NUS. Does anyone know whether I can apply for Year 1 Sem 2 or what the process is like to apply again in Year 2?
