Your explanation is incredibly nice and simple. Thank you so much for explaining complex ideas and distilling them into easy-to-understand concepts. I'll wait for your next video!
Thank you so much! I've been struggling reading the introduction to tracking theory by the pilons and your series has been much easier to learn from. By the way, I know many people are asking, but when could we get a part 4? I'm excited to put it all together and I'd like to use odometry for spin up this season! Keep up the great work!
when calculating the x coor, can you explain why the theta used is the same as the theta used in the y coor calculation? Isn't theta calculated with the right and left tracking wheels? then say the robot were to get pushed purely sideways, in the formula, the x coor would not reflect that change? thanks
If the robot is purely pushed side ways theta doesn't change i.e its 0. In the implemenation you can make a seperate case for when theta is 0. Basically you set the sin(theta/2) to be 1 instead and the rest of formula stays the same.
Because you're taking a two that isn't there from the inside, it's the same as dividing by two, or multiplying by 1/2. As such, the denominator of 1 - cos(theta) becomes a 2, which leaves you with (1-cos(theta))/2.
hi, bro! use left tracking wheel and right tracking wheel is order to get the degrees of robot changed??? so , if use gyro, Can I reduce the use of one tracking wheel and only use two tracking wheels???hope for your reply，thanks
man you got everyone waiting for part 4.. seems like something went wrong. could you please update us on ur situation and try for part 4 since it would very useful to have a example and see odometry in use/explained.
Hello, i was wondering what thoughts you have about using an inertial sensor to find absolute position, do you think it would be more or less actuate then tracking wheels, thanks
Thank you for the videos, I was waiting for this video, I working in a odometry system, I use 2 pid Controls, one is for the lineal motion and the other one is for the turns, so finally I have a odometry system with the PID to control the velocity of the robot, do you think that is a good idea? Your videos of odometry are very helpful, good job, you help me so much to develop my odometry system
Hi, thank you so much for going through the effort and time to explain the math so well. I just a one question about how to measure the distance from encoders to tracking center? Is there any very accurate and consistent way to do so? Thanks so much
Hi can make an arduino code for implementing odometry using only 2WD smart chassis kit. The idea is to make the robot car to go to a specific set (x,y) coordinate using only two speed sensors and using Arsuino IDE. I'll pay you for a fine price cuz really i's so hard and there'a not enough info on yt and internet. It's also our project btw.

Will there be a part 4 soon? Could use it for spin up.
can we please get part 4 pretty please with a cherry on top pretty please rex liu
When is part 4 coming out, this is really helpful.

When is part 4 :
Thank you so much, im only doing ms vrc and this was one of the only tutorials i could understand
Great video! When are you making a part 4?
When will part 4 be coming out?
Great video can’t wait for part 4
Thank you for the detailed explanation. We're eagerly waiting for the code implementation example of odometry.

Need a part 4 right now
My robotics teams autonomous would be so much better with odometeyb
Hi, good Job. Do you know when Part 4 will be online? Greetings from germany.
When are you making the part 4 video?
Do you plan about visual odom video?
@5:06 I was wondering how does factoring out a 2 place a 2 in the denominator of 1 - cos( Θ)?
Because you're taking a two that isn't there from the inside, it's the same as dividing by two, or multiplying by 1/2. As such, the denominator of 1 - cos(theta) becomes a 2, which leaves you with (1-cos(theta))/2.

so, part 4 not coming? 🥺
man you got everyone waiting for part 4.. seems like something went wrong. could you please update us on ur situation and try for part 4 since it would very useful to have a example and see odometry in use/explained.
in the end when calculating the y coordinate when substituting shouldn't it be delta r * theta
have plan for part 4?
nice video.... clear and easy to understand.
how about Part 4? I think many viewers waiting for your next tutorial
Your videos are awesome

Less accurate
Please do a part four.🙏🙏🙏
Please do the next video!

part 4? great vid
Where is part 4
Hi, thank you so much for going through the effort and time to explain the math so well. I just a one question about how to measure the distance from encoders to tracking center? Is there any very accurate and consistent way to do so? Thanks so much
physically measure the distance using a ruler or calipers...
Rex wheres the next video
part 4?
ah yes the long awaited sequel
Bro please give us the part 4 already !
still waiting for a part 4
why they don't just use an accelerometer ans a gyroscope
Part 4?
Y is it called vector ?
We are only finding a single value ??

Part 4!!
episode four please!!!!! 🤡🤡🤡
