In this video, I explain how to save motors by using 1 motor to power multiple mechanisms simultaneously. I also share some examples from my 550-point robot....

2016年10月24日 · To solve the problems, an alternative flux estimator, implemented with a single second-order generalized integrator (SOGI) and a frequency-locked loop (FLL), is discussed for induction motor drives.

2021年10月6日 · Abstract: Phase-locked loops (PLLs) and frequency-locked loops (FLLs) are of importance in power and energy applications. Both technologies have been introduced to speed-sensorless- controlled motor drives, and increasing applications of PLLs and FLLs for speed estimation are foreseen.

Abstract: The purpose of this study is to describe a current control strategy for reducing torque ripple in a 6/4 three-phase switched reluctance motor (SRM). The proposed current control approach consists of a second-order-generalized-integrator (SOGI) based on frequency-locked-loop (FLL) controller and a two-degrees-of-freedom (2DOF) PID ...

Most articles on Lego EV3 PID algorithms use a line follower example (using the Lego Colour sensor) to describe it. This article will use the Lego Gyro because it might be a conceptually easier for new FLL participants to understand. A PID …

2018年6月8日 · This is a compact robot design that uses 4 medium motors. It also has a 2 color sensors, 1 gyro sensor and 1 ultrasonic. Two of the motors have been positioned upwards to enable easy attachments. The robot features an outer wall for alignment on walls and mission models. The two color sensors are well positioned for aligning on lines.

2023年10月14日 · The video shows an FLL concept design that uses 2 motors and a distribution transmission to drive 4 powered attachments (one at a time). One motor shifts the transmission between one of four possible outputs. The other motor drives the output to control the attachment.

2022年8月10日 · Experiment with resetting the motors. Make sure you reset the motors regularly, preferably at the start of every round. Two concepts are important for robotics competitions - consistently navigate and position the robot exactly where we need it to be on the field, and builing attachments that would accomplish a mission once we have reached it.

2015年10月3日 · Programming motors for competitions like the FIRST LEGO League (FLL) or World Robotics Olympiad (WRO) is not very different from programming the motors in the STEM classes. But there are a few things you should have in mind.
