@will The safest bet is to choose a wheel + hub from the same manufacturer. If you want to connect the wheel directly to the motor’s output shaft, you need to find a hub with the same inner diameter as the motor’s outer diameter, and then a wheel which is compatible with that hub. Note that there is no “standard” mounting pattern for wheels / hubs, but the most common shaft diameters seem to be 4mm, 6mm, 10mm and 1/4", 3/8" and 1/2".
@CBenson For my robot I am using the same motor as this but I can’t find any tracks that fit with it.can you help me find one?I want something like this https://www.robotshop.com/en/tamiya-track-and-wheel-set.html
Great job guys! Great tutorial…u explained all the things in very simple manner! Keep it up…
Hi so i have a question about robotics in general. Has anyone ever built a robot that can assemble a skateboard? If not, is it possible because I would want to create that and if so, that could change the skateboarding community forever. So creating a arm that could assemble a board? Thanks!
@Sanaan Akhter We don’t see why it would not be possible, the question would rather be “would it be profitable?”
Hey its me again, and thanks for that answer alot. I have another question, if I’m learning how to build my first robot, would building a robot arm be fine for my first one or is the math in that too complex?
@Sanaan Akhter A robot arm can be fun and is not too hard. It’s important to know the torque required at each joint, and the following can help: https://www.robotshop.com/blog/en/robot-arm-torque-calculator-9712
Some of the math (inverse kinematics equations) is explained at the bottom of this manual: https://www.robotshop.com/media/files/pdf/robotshop-multi-purpose-robotic-arm-guide.pdf
this lesson is really helping me out , cnt wait for more.
I am confused because you lists a lot of motors but which one can i use to make a drone or something like that
@Tushar Almost all multirotor UAVs currently used brushless DC (BLDC) motors. We have a complete tutorial series about how to build drones: https://www.robotshop.com/blog/en/robots/gorobotics/tutorials/how-to-make-a-drone-uav
Its nice and amazing …
which type of motor I use to produce a torque of 42N-m
@Bhanu Many different motors can produce torque, but if you specifically want the motor as part of a wheeled or tracked propulsion system on a mobile robot, a brushed DC gear motor is often the best value.
3 Lessons in and not sure who the proofreader of these lessons was but just FYI, there are numerous grammatical errors in the first 3. Overall, liking the lessons so far. I have just found these and am going to follow them through and purchase the parts as recommended to see the outcome.
@Peter Walker We do appreciate the feedback. If you can inform us of specific errors it would be appreciated, and we would be happy to make the corrections. Please e-mail us at [email protected]
Carlos I am making a mobile robo with tracks and I need a motor which will allow a small camera to turn 360 degrrees round and also slightly tilt upwards, which one would u recommend/?
@Dameer Most small pan/tilt units use RC servos, so if you want 360 degree motion but plan to control it manually, consider a continuous rotation servo for the base, and a normal servo for tilt.
nice work
