Hey there, I am planning on going to a robotic competition and would like some insight on what kind of components will be best suited. I am pretty familiar with Arduino hobby projects but I have only been using components that are not very precise as it was just for fun.
In the competition, speed and precision in the components will be vital and that’s why I am writing this message to ask for suggestion on the available components sold in Core Electronics. The task is to build an autonomous vehicle to collect and deliver loads. The vehicle is size constraint to roughly 50cm^3.
The main question I have is:
What kind of motors and tires can be used to have the quickest run and be precisely repetitive? Timing is vital in the competition. I have previously used DC motors and an Arduino motor shield, the movement of the robot was too unstable to run the same every time
To ensure the robot can be in a precise location everytime to pick and deliver the load, what distance sensors is recommended? I have tried using the ultrasonic sensor but the data from it is too noisy to reliably position the robot.
What kind of overall set up (batteries+motor driver) is recommended to ensure that the robot will run the same every time?
Would it be possible to come down to the shop to have a discussion with any of you regarding our project? We currently have not brought any components yet. It will be great to have some advice from local experts.
