Lego Motions — Move Tribot Around
And Backward…Five Programs Files — Episode #05
Let’s get Tribot there and back! videos? click here now!
Follows five codes for our study of the EV3 world :D
05_a_EV3_back and forth_v1
Get Tribot v1 into a journey to one or more places and back again: real round trip;
05_b_EV3_around square_v1
Places the Tribot v1 in a rectangular journey, following the sides of the rectangle;
05_c_EV3_coasting_issue_v1
When you run a motion block using Brake At End parameter, the firmware keeps track of how far the motor actually moved (the firmware is the program that runs on the EV3 and executes the program you write). Because of the motor coasts to a stop, it will move nothing more in this first code but 2 rotations …
05_d_EV3_coasting_issue_v1
it will move a little more than the duration you specified in the first block, and the next motion block that runs will adjust its duration to account for extra distance…
05_e_EV3_coasting_issue_v1
or you can cancel this behavior by using Wait Block together with Steering Block in Off Mode.
Please see the video above for more information.
Curiosities:
That’s all for now!
Thank you!
See you in the next Episode.

Troubleshooting
- I have to improve the lighting; I had reflex problems, I’m sorry: /;
- When disconnecting the Tribot v1 and then connecting it again, the app does not read the distance sensor; We have to close and open the app so we can see the sensor data in Port View: /;
- The Tribot v1 did not make the square layout perfectly; Our L-loop has to be improved: /;
- If you have any suggestion send it; So that you can put it in the list here :)
