Adapting a Low-Cost Selective Compliant Articulated Robotic Arm for Spillage Avoidance

Abstract

Flexible automation systems provide the needed adaptability to serve shorter-term projects and specialty applications in biochemical analysis. A low-cost selective compliant articulated robotic arm designed for liquid spillage avoidance is developed here. In the vertical-plane robotic arm movement test, the signals from an inertial measurement unit (IMU) and accelerometer were able to sense collisions. In the horizontal movement test, however, only the signals from the IMU enabled collision to be detected. Using a calculation method developed, it was possible to chart the regions where the obstacle was likely to be located when a collision occurred. The low cost of the IMU and its easy incorporation into the robotic arm offer the potential to meet the pressures of lowering operating costs, apply laboratory automation in resource-limited venues, and obviate human intervention in response to sudden disease outbreaks.

Linear Stepper Actuation Driving Drop Resonance and Modifying Hysteresis

“…To characterize the linear stepper motorized actuator (Zaber), an inertial measurement unit (IMU) 26 was attached to it, and readings from it were recorded as the actuator was made to travel at 4 mm/s. To detect for any directional differences, measurements were made with the actuator moving forward and backward.…”

Aplicação Da Simulação De Eventos Discretos Como Ferramenta Computacional De Análise E Tomada De Decisão Em Processos De Automatização De Ensaios Químicos Em Laboratórios De Análise Mineral / Application of Discrete Events Simulation as a Computational Tool for Analysis and Make a Decision in Chemical Test Automation Processes in Mineral Analysis Laboratories

“…Lalongo et al (2015) afirmam que esta automação total do laboratório demanda um grande esforço da empresa em termos de recursos econômicos, alterações estruturais e processuais, e até mudanças culturais da equipe de funcionários. Entretanto, tem-se constatado ganhos relativos à produtividade, qualidade e custo oriundos da implementação desta tecnologia no processo de análise laboratorial (DOLCI et al 2017;MCMORRAN et al, 2016).…”

Development of an Intelligent Robotic System for Plasma Processing of Industrial Products with Complex Shape

“…Nowadays, industrial robots are widely used, manipulators are used for loading, packaging, plasma or laser cutting and melting as well as for various types of surface treatment: painting, spraying coatings, etc. [1][2][3][4][5][6]. With regard to the thermal plasma spraying process, the main task performed by the robot arm is to move the plasma source or substrate in order to expose the substrate surface to the plasma flow with the coating particles in a stable, consistent and repeatable manner.…”
