Products and Reference Designs
Over the years, we have found that many customers need similar technology solutions, but they need them implemented in special ways. This has caused us to develop our library of references designs. We use these as starting points for doing custom work. This makes projects happen cheaper and faster, while preventing us from having to constantly re-invent the wheel. In the case of our custom wheel designs, we mean that quite literally.
The EM Bot (pronounced M Bot) is our omni-directional mobile base reference design. We run across many customers who would benefit from a mobile base that is modular and can be scaled up or down for particular applications. We built EM Bot to serve as a basis for those custom applications without our customers having to expend the additional time and money to develop a fully custom platform. To operate EM Bot and it's variants, we have a full suite of tools called Base Suite that make bringup and utilization of an omni-directional platform much easier and cheaper than in the past.
iPDS - Intelligent Power Distribution System for Robots
Bringing up a new robot electrical system can be a major challenge. Early mechanical design, packaging, sensor selection, software behaviors, among other criteria, can all cause a domino effect whereby the electrical system must change quickly. Constantly making these changes usually will have the effect of a prototype rarely being available for testing, which is the entire point of the prototype. To address this major problem in robot product development, we developed our Intelligent Power Distribution System. The iPDS serves as a development platform that lets robotic hardware teams iterate and make changes very quickly. It provides DC voltage conversion, fusing and busing, as well as an Atmel micro-controller to serve as the stable basis for you to build your electrical architecture on. Electric Movement will release this as a dev kit in 2017.
iPDS is a modular architecture for power distribution that could be used in any design. It has multiple DC-DC converters onboard and allows for configurable outputs, for the purpose of powering components without the need for discrete power supplies, cases, and the multitudes of connectors. Our smart system gives feedback through sensors to reduce effort in bring up, testing, and troubleshooting.
Custom Omni-directional Mecanum Wheels
In our opinion, more robots should use omni wheels. The major problem with these wheels is that there are very few options to buy off-the-shelf production-grade mecanum wheels. This state of the market caused us to design our own wheels with a formulaic approach. This reference design allows us to vary parameters within the wheel to accommodate different environmental conditions like terrain and payload-ability. Want to put a brushless hub motor inside a mecanum wheel built specifically for you application and in so doing, accomplish mechanical packaging nirvanna? You came to right place!
RFID Ignition Controller
Key management in large commercial fleets has always been a challenge. When working recently with a large corporate customer here in Silicon Valley, we came up with a way to eliminate the need for keys altogether and instead, use RFID employee badges to turn a vehicle on and off. This system offers a streamlined way to for users to operate pool vehicles without ever having to worry about someone taking a key home with them at the end of the day.
Time Delay Power Supply
Frequently, in working with our electric vehicle customers, there is a need to power 12 volt electronics while a vehicle's ignition is off. This caused us to design this Timer Delay Power Supply system that converts traction pack voltage to 12V and turns on automatically when the ignition circuit is opened. The time can be set to a wide range, but we typically set these to 4 hours. The module is assemble in-house from a custom PCB with sturdy, production-grade harness, potted with thermal compound into an aluminum case that we machine in-house.
