Quote from: ohad z on January 21, 2018, 11:13:27 PMA couple of questions/comments: There seem to be a few inconsistencies (unless I don't understand the notations) in the drive/steer motor definitions above: CAN IDs are 1-4 (steer) and 5-8 (drive), right? The table seem to indicate 0-3 and 4-7. Also, the wheel order is FR-FL-RL-RR (there is mention of FR-FL-RR-RL as well)If we are short of SRX units, we may want to experiment with SR or PWM for the drive motors - they do not require any of the fancier modes and we are using them with no feedback as of now. Even if we want to use feedback loop for them, since we only have one distance encoder, we may need to use the software PID since SRX PID would require 4 encoders. This may free up SRX for the intake and claw.Arm is long and heavy. Will have to make sure whatever sensor used (Potentiometer) is sensitive and with enough resolution to be able to control the end of the arm with enough precision to avoid sway and missed goals. If in doubt, we may need to aim higher and let the cube drop.How about IR sensor for the cube in the intake?Some feedback (pot or encoder) for the extension mechanism A concern was raised about engaging cubes that arrive at an angle and one idea was to engage different sides of the intake separately to get the cube aligned. Would require additional controller.
