For the second a part of our RoboHouse Interview Trilogy: The Working Lifetime of the Robotics Engineer we converse with Wendel Postma, chief engineer at Undertaking MARCH VIII. How does he resolve the conundrum of integration: getting a bunch of single-minded engineers to in the end serve the wants of 1 single exoskeleton person? Rens van Poppel inquires.
Wendel oversees technical engineering high quality, and shares answerable for on-time supply inside funds with the opposite mission managers. He spends his days wandering across the Dream Corridor on TU Delft Campus, encouraging his crew to discover new avenues for growing the exoskeleton. What is feasible inside the time that we now have? Can conflicting design options work collectively?
Bringing dangerous information is a part of the chief engineer’s job.
Undertaking MARCH is iterative enterprise.
Most of its office drama comes from the urgency to ship no less than one important enchancment on the present prototype. This 12 months’s obsessions is weight; a lighter exoskeleton would require much less energy from each pilot and motors. Self-balancing would change into simpler to understand.
So as to not weaken the body of the exoskeleton, there was lots of enthusiasm to experiment with carbon fibre, which is each a light-weight and robust materials. One thing, nonetheless, obtained in the way in which: the crew struggled to discover a pilot.
My job is ensuring that ultimately we don’t have 600 separate elements, however one exoskeleton.
“Having a take a look at pilot is essential if we’re to achieve our objectives,” Wendel says. “Our present exoskeleton is constructed to suit the actual physique form of the particular person controlling it. The design just isn’t but adjustable to a distinct physique form. So it’s essential to get the pilot concerned as shortly as attainable.”
Not having a pilot was irritating for all the crew.
Their dream of making a self-balancing exoskeleton was at risk. Wendel needed to step up: “As chief engineer you need to make robust selections. Carbon fibre is powerful, however not versatile and tough to machine. That’s the reason we switched to aluminium, as a result of it’s simpler to change even after it’s completed.”
“It was an enormous disappointment,” Wendel says. “A few of us had already completed trainings for carbon manufacturing. Carbon elements have been already ordered. The crew felt let down. We had spent a a lot time on one thing that was now unimaginable – due to the delays brought on by having no pilot.”
“I learnt that bringing dangerous information is a part of the chief engineer’s job. The subsequent step is to take a look at find out how to convert the engineers’ enthusiasm for carbon fibre into new options and to redeploy their private qualities.”
Wendel says the job additionally taught him to contemplate 100 issues on the identical time. And to make sacrifices. Undertaking MARCH entails lengthy workdays and perhaps not seeing your folks and roommates as a lot as you prefer to.
As a naturally curious particular person, Wendel discovered that curiosity have to be complemented by grit to make it in robotics. You usually have to go deeper and examine in additional element to make an excellent determination. “It’s exhausting work. Nonetheless, that can be what makes the job a lot enjoyable. You’re employed in such a extremely motivated crew.”
That can be what makes the job a lot enjoyable.
The carbon story ended properly, although.
When the crew did discovered a pilot, hard-working Koen van Zeeland, the selection for aluminium as a base materials paid off. By a strategy of weight evaluation, elements can now be optimised for an ever lighter exoskeleton.
The Undertaking MARCH crew continues to develop by setbacks and has doubled-down on their efforts to create the world’s first self-balancing exoskeleton. In the event that they succeed, it is going to be an enormous success for this distinctive method of operating a enterprise.
