Bipedal humanoid robots have been around for over 30 years, but developing and implementing intelligent motion algorithms to keep their moves from looking Frankenstein-esque have remained a challenge. Using NI hardware, LabVIEW, and third-party add-ons, a team of engineers at the Temasek Polytechnic School of Engineering have built a teenager-sized humanoid robot with a smooth gait.

The project focused on developing a user-friendly graphical interface to implement motion control algorithms. Engineers used LabVIEW to create control software that students used to easily develop and debug the program, and they’re going to be able to flexibly adapt and redeploy the program in the future on other robotics projects. PXI-8101 was the main system controller and students programmed wireless LAN using the LabVIEW Internet Toolkit. The LabVIEW MathScript RT Module executed The MathWorks, Inc. MATLAB® code to generate gait trajectory.

 

LabVIEW reduced development time to one semester, made it possible to perform motion simulation with SolidWorks, and executed code created with MATLAB. The bipedal humanoid robot made its debut at the SRG 2014 Singapore Robotics Games.

We may be nearing the end of the line for diesel buses in the United Kingdom as hybrid powertrains take the road. Vantage Power, a company specializing in electric and hybrid systems for buses and heavy-duty vehicles, has developed a hybrid powertrain that cuts fuel use by 40 percent. This makes it the most energy-efficient hybrid bus on UK roads.

Vantage Power made CompactRIO the core of the hybrid vehicle control system. CompactRIO controlled each power delivery component and analyzed and logged large sets of acquired data. Vantage Power also used LabVIEW to implement an advanced Kalman filter algorithm, which provided crucial onboard estimation functions for battery charge state, health, and thermal management.

 

The hybrid bus has passed all required tests and is currently beginning trials in a public service fleet in the UK. This hybrid bus is driving change on the road and turning our lines green.

Unmanned vehicles are extremely useful in situations that are dangerous for human operators. The ILX-27 is an unmanned helicopter designed to support special military operations. The helicopter’s applications include reconnaissance, cargo transportation, and evacuations, but before the ILX-27 can answer the call of duty it must first pass a series of ground and flight tests.

 

The Institute of Aviation (ILOT) designed the ILX-27 in cooperation with the Air Force Institute of Technology and Military Aviation Works. After the helicopter was built, engineers working on the project needed to create a test system to obtain reliable data retrieved from ground and flight tests.

ILOT used NI LabVIEW, DIAdem, and CompactRIO to create a measurement system that managed the helicopter’s construction and monitoring. ILOT used CompactRIO as the main data recorder and DIAdem to store measurement data obtained from the tests.  

 

Engineers used LabVIEW to monitor the vibration levels of multiple helicopter parts under inspection and control the parts in case of an emergency. For ILOT, LabVIEW facilitated data analysis and the presentation of results, leaving time for the company to concentrate their efforts on the helicopter tests.


ILOT achieved the overarching goal of the project performing ground and flight tests of the ILX-27 on a proving ground. But testing on the ILX-27 isn’t done quite yet. NI’s flexible hardware gave ILOT the tools to further expand the trajectory of the project. The company plans on adding a module to the helicopter rotor head to gain insight on the dynamics of ILX-27.

The game of chess is complex and requires intense strategy, and developing a robot that can play the game requires the same. So when students at IUT1 de Grenoble decided to create a chess-playing robot to compete in the French Cup of Robotics 2011 Chess’up! Competition, they turned to NI LabVIEW for help.

By using LabVIEW to design and program software, the students were able to create easy communication between the robot’s NI sbRIO-9632 module “brain” and its movements. The students were able to operate complex platforms simply and quickly because of the uncomplicated approach to programming that LabVIEW provides.

 

The chess-playing robot took 41st place in the competition, a very encouraging success for students that received their BAC two to three years prior and were competing for the first time. The robot ranked higher than many engineering schools, and the results were the best IUT1 Grenoble has seen in its eight years in the competition.
