Autonomous delivery vehicles …..coming soon!

delivery robot

Swiss start-up company TeleRetail is testing a prototype delivery robot that delivers groceries/ small packages autonomously.

Called “mobile trunks” these autonomous delivery robots are small containers on wheels equipped with sensors, intelligent software and powerful maxon DC motors. Made and designed to travel autonomously, reliably and without obstructing or endangering anyone, these small robots reduce congestion on the roads and are more economic to run than an electric car.

Maxon brushless DC motors, the EC 90 flat, features in the mobile trunks. Developed in conjunction with maxon engineers since 2016 the vehicle is still in it’s infancy. Before these delivery robots can be produced en-masse, laws need to change. Currently these types of delivery robots can only move around with the use of special permits away from the large bustling cities.

Brushless DC motor with temperature sensors.

BLDC motor with temp sensors1-shadow450px

When prototyping with Brushless DC motors information is key to product success.

Pictured here is a highly customised brushless DC motor developed for special aerospace applications. The 200W nominal 30mm diameter has had a special winding wound to suit the unique requirements of the application where the motor needs characteristics for driving and generation. It is a 4 pole topography with a sealed stainless steel body and welded flanges. The application for this brushless DC motor requires operation for very short bursts of power at over 500W. To facilitate testing that gives design engineers absolute confidence the winding will never exceed its thermal limits a platinum thin film temperature sensor has been fitted in contact with each phase. This allows the R&D staff to slowly increase the duty cycle whilst monitoring temperature and develop controller functionalities around the thermal limits. In addition the motor has been assembled with a planetary gearhead that is quite special in itself. The gearhead ratio has been slightly adjusted to allow for smaller planetary gear diameters. The smaller diameters allow for an additional set of gears on the output stage increasing the torque capabilities. A special 2RS rubber sealed bearing has been incorporated along with a customer specified axial threaded bore in the middle of the shaft. At the rear of the motor is a 4,096 quad count encoder facilitating the smooth zero cogging motion control.

Saving the lives of preemie babies.

Paul-2

Paul is a robotically simulated training model of a 27 week old preemie baby. Created by an Austrian paediatrician to help train medical practitioners, maxon motors replicate the breathing movements of the baby.

Meet Paul. The smallest and most advanced high-end patient simulator in the world. Paul is a 27 week old preemie. He is 35cm long and weighs 1kg. He breathes on his own with a consistent heartbeat. His chest gently moves up and down, veins and arteries are visible under his thin skin. Paul needs artificial respiration and will sometimes turn blue.

Born to train medical staff in emergency situations that occur every day in neonatal intensive care units, the creator of Paul is Jens-Christian Schwindt, an ex-paediatrician in the Division of Neonatology of the Vienna General Hospital. In 2015 Schwindt started his company SIMCharacters, that arose from a need where “Critical situations in preterm care have to be trained time and time again, under as realistic conditions as possible, to ensure that everything goes equally smoothly in a real crisis” says Schwindt. With the ability to evoke emotions and cry, the baby looks exceptionally lifelike and is full of high-technology on the inside. His skull hosts a Linux system, he is charged cordlessly by induction using a customary charging pad. Paul can be operated for up to two hours. When he has difficulty breathing or the oxygen saturation drops, his head turns blue. Sophisticated hardware and software fit into a silicone skin.

maxon DC motors, gearheads and sensors ensure that the thorax and abdomen move in accordance with the programmed test scenarios. Three DCX 12mm motors with gearhead and sensors are used – two for Paul’s thorax and one for the abdomen. Another maxon DCX 6mm motor moves a valve in the lung of the simulator, with a total of 40 motors installed. The motors were selected for their torque, density and quiet running. The robust design and the ironless maxon rotor make these motors a perfect fit for this unique application. Maxon’s DCX motors are brushed and available in sizes from Ø 6 – 35 mm. They can be easily configured online and customer can select from graphite and precious metal brushes, sintered and ball bearings, and many other components.

Renewable wind energy harvested from an altitude of 500m.

Clean energy from alt 500m-Kite

A new method of garnering renewable energy is being explored and it’s not from wind turbines.

A Dutch start-up company, KitePower is creating a system to produce green energy from Kites. In collaboration with the Delft University in the Netherlands, the approach consists of a generator on the ground that is connected directly to a cable winch that has a steered kite attached. The kite pulls the cable upward by flying in a figure-8 pattern creating a strong tractive force with the ability to reach heights up to 500 metres. When altitude is achieved the cable is retracted (using very little energy) and the procedure is repeated.

The device offers an attractive alternative to diesel generators and wind turbines. In comparison the kite needs less material for construction, is more mobile and can flexibly use winds up to 500m. Of particular benefit to secluded communities, military camps or remote islands the first commercial version is due for release at the end of 2018.

Maxon motor is one of a few companies assisting KitePower. Maxon’s expertise is in developing the control unit for the steering movement of the kite. This included integrating DC motors, different sensors, transmitters, receivers and batteries while considering extreme radial forces on the gearhead. The device uses maxon’s Ec-i 52 DC motor with planetary gearhead and encoder. This combination is usually found in robotics applications for its high torque and compact design.
