Brushless DC Motors in Robotics: Powering the Future of Automation

Control algorithms are at the heart of optimizing the performance of brushless DC motors (BLDC), enabling these motors to deliver precise speed regulation, torque management, and smooth operation. Whether it's sensorless control or closed-loop feedback systems, the choice of control method significantly impacts the motor's efficiency, responsiveness, and overall effectiveness. In this exploration, we delve into the world of control algorithms that drive BLDC motors to their peak performance.

One of the most prominent control techniques for BLDC motors is sensorless control. Traditionally, position sensors were employed to provide real-time feedback about the rotor's position, allowing the controller to commutate the motor accurately. However, sensorless control methods have emerged as an alternative, eliminating the need for additional hardware and potential points of failure. These algorithms rely on the back electromotive force (EMF) generated by the motor to estimate the rotor position, thus achieving commutation without external sensors. Sensorless control is particularly advantageous in applications where adding sensors might be impractical or cost-prohibitive.

Closed-loop control systems, on the other hand, utilize sensors to provide real-time feedback and adjust the motor's operation accordingly. This type of control is known for its precision and accuracy. By constantly monitoring variables such as speed, current, and position, the controller can make rapid adjustments to maintain the desired performance. Closed-loop control is vital in applications that require high levels of accuracy and responsiveness, such as robotics and industrial automation.

Another important consideration in control algorithms is the choice between trapezoidal and sinusoidal commutation. Trapezoidal commutation is simpler and often used in applications where the motor doesn't need to operate at very low speeds. Sinusoidal commutation, on the other hand, provides smoother torque delivery and is suitable for applications requiring precise speed control across a wide range of speeds.

Advancements in microcontroller technology and digital signal processing have paved the way for more sophisticated control algorithms. Field-oriented control (FOC), for instance, offers precise torque and speed control by transforming the three-phase AC currents and voltages into a two-coordinate system. This method allows for independent control of torque and flux, resulting in smoother performance and reduced torque ripple.

In the realm of robotics and automation, brushless DC motors (BLDC) are emerging as the driving force behind precision motion control, high torque-to-weight ratios, and quiet operation. From collaborative robots (cobots) to unmanned aerial vehicles (drones), BLDC motors are playing a pivotal role in shaping the future of automation by providing the efficiency and performance required for a wide range of applications.

Collaborative robots, or cobots, are designed to work alongside humans in industrial settings. They require motors that are not only powerful but also safe and responsive. BLDC motors fit the bill perfectly. Their ability to deliver high torque at low speeds makes them well-suited for tasks that require precise and controlled movements, such as picking and placing objects on a production line. Moreover, their compact size and lightweight nature are advantageous for integrating into cobots without compromising their overall agility and safety.

Drones, another rapidly advancing area of robotics, heavily rely on BLDC motors for propulsion and maneuverability. The lightweight design and high power-to-weight ratio of BLDC motors enable drones to achieve impressive flight times and carry payloads effectively. Additionally, the precise speed control and rapid response of these motors allow drones to navigate tight spaces and execute complex aerial maneuvers with ease. Whether it's aerial photography, surveillance, or package delivery, BLDC motors are the workhorses that keep drones airborne and operational.

Industrial automation is yet another domain benefiting from the capabilities of BLDC motors. From conveyor belts to robotic arms, these motors provide the necessary muscle for machines to move, lift, and manipulate objects efficiently. The ability to precisely control speed and position enhances production processes, minimizes errors, and improves overall productivity. The quiet operation of BLDC motors is an added advantage, contributing to a more conducive and less noisy working environment.

The application of BLDC motors in robotics and automation isn't limited to just these examples. From exoskeletons that assist in rehabilitation to robotic surgical instruments that demand precision beyond human capabilities, the versatility of BLDC motors continues to expand the possibilities of what robots can achieve.

In conclusion, brushless DC motors are ushering in a new era of robotics and automation. Their combination of power, precision, and efficiency makes them indispensable for tasks ranging from delicate maneuvers in cobots to high-speed flight in drones. As technology advances and robots become increasingly integrated into our lives, BLDC motors will remain at the forefront of innovation, driving the automation revolution forward.

The choice of control algorithm significantly influences the performance of brushless DC motors. Whether opting for sensorless or closed-loop control, trapezoidal or sinusoidal commutation, or even more advanced techniques like field-oriented control, engineers must carefully consider the specific requirements of their applications. By mastering these control algorithms, engineers unlock the full potential of BLDC motors and ensure their optimal performance across a wide range of industries and applications.

Estimation of Tool-Tissue Forces in Robot-Assisted Minimally Invasive Surgery

The advent of robots in surgery started in 1994 when the first AESOP (voice-controlled camera holder) prototype robot was used clinically in 1993. AESOP was then marketed as the first surgical robot ever in 1994 by the US FDA. Since then Robot-assisted minimally invasive surgery (RAMIS) has gained immense popularity over the last two decades. Statistics show that more than 50% of errors performed by surgical trainees are due to excessive force. This may often lead to irreparable damage. RAMIS reduces the error percentage of tool-tissue interaction forces significantly, it is much more accurate than an open surgery or laparoscopic minimally invasive surgery. Although it may seem like this approach saves the patient from excessive trauma this method is limiting. This is because the surgeon is not directly controlling the machine. Which means the tool might lose direct contact with the surface of surgery, i.e. loss of tactile information for the surgeon. This entire process of relaying tool-tissue force information to the surgeon is the haptic feedback or force feedback. The tool-tissue interaction forces affect the efficacy of the surgery to a great extent, so it is imperative for RAMIS to overcome this obstacle to reach its full potential. 

This disparity in information is the main reason RAMIS has not reached its apogee. The lack of haptic feedback, tactile sensing, and tool tissue force-sensing contributes to this method’s dubiousness. Several attempts have been made over the years for the sensorization of surgical instruments but even the most of developed sensory systems required to alter the standard shape of the surgical tool (as it may affect the handling of the surgical tool and possibly the amount of tool-tissue interaction forces), are not suitable in terms of size or the installation place, require the filtration of noise signals, or have an unsuitable range of measurement. In addition to that they make the instruments bulky and complicate the process of sterilization. The size of force sensors, and incision ports, the sterilization of tools at high temperature and the disposable nature of surgical tools have so far prevented the integration of end-effector/tissue force sensing in RAMIS. 

Scientists soon understood that sensors are definitely not the way to go.

There have been multitudes of research solutions for this problem. None of the methods seemed to provide a complete remedy. However, a recent research brings forth an answer to this long-lasting issue by proposing a new algorithm to estimate the tool-tissue force interaction in robot-assisted minimally invasive surgery in a way that it does not require the use of external force sensing (sensor-less). This incredible feat was achieved by applying a neural network method to estimate the tool-tissue force interaction during a grasp manoeuvre in RAMIS for future application in providing haptic feedback to surgeons. Its distinctive features reside in the fact that it considers a black box approach regarding the whole mechanism, thus rendering the analysis of the grippers mechanism unnecessary. The proposed method is based on utilization of the current of the gripper-actuating motors as well as a detailed examination of the various stages of a grasping motion. In contrast to existing algorithms in literature, this model does not require external sensors or equipment such as vision systems, predicting sufficiently both small and large forces.

This model was tested online and offline to check its feasibility and feedback system. The results showed that the developed algorithm can estimate the tool-tissue interaction force during the grasp online and could thus allow haptic feedback in robotic surgery to be provided. This model can predict both large and relatively small forces which was an issue in the algorithm developed by Zhao and Nelson (2015). The model developed by Zhao and Nelson used motor current and was the first model to tackle the existing problems of RAMIS without the use of sensors. Their model utilized the Gaussian Process Regression, which unfortunately failed when the target went out of range. This research tactfully handles the problem of GPR not being able to predict the outcomes when the target goes out of the range of the dataset. This problem was combated with the help of neural networks. This approach was inspired by Yu et al. (2018) who proposed a cable tension based method to estimate external forces and utilized a back propagation (BP) network to estimate resistance parameters such as friction to aid in the force estimation. Along with Yu, Aviles et al. (2015, 2015) also inspired this algorithm with his seminal paper on combined vision based methods with recurrent neural networks to estimate tool-tissue interaction.
