Our engineers offering Perth Robotics Development services have something like a combined 50 years worth of experience in the robotics field, from teleoperated and semi-autonomous mobile robotic applications, to custom software and/or custom hardware for general automation solutions, signal processing and control systems. Our knowledge base started in NSW and ACT, but now we primarily service East Coast Queensland.
We have developed autonomous mobile robots for air, sea and ground. Our professional experience started with developing various control and sensor systems for small underwater vehicles in the late 1990's. We where fortunate enough to have been involved in one of the first self-driving car R&D projects back in early 2000's using a 4WD (to support computers for the large processing requirements). For an overseas client we developed a low profile (70mm high) semi-autonomous mobile robot platform for manikin/dummy mounting to simulate people moving (for vehicle crash safety and collision development by German R&D car manufactures). We have been fortunate enough to have been invited to the bulk of the German R&D car manufactures where they develop and test self-driving and driver assist development systems. We have developed various solutions for 2cm accuracy precision steering-guidance solutions for various types of Agriculture tractors (via the CAN bus and ad-hoc methods), which are still used by 1000's of tractors all over the world. We have retro fitted Quadbikes to allow semi-autonomous control via GPS way points. We have custom developed various indoor mobile robotics for indoor localistion and SLAM R&D purposes.
Robot navigation is the task where an autonomous robot moves safely from one location to another. This involves three primary questions:
For robotic localisation and obstacle avoidance we use sensors to solve the problem. To move along the planned path, we use control systems.
We have a deep understanding of signal processing and sensors of various types. We appreciate sensing is a hard problem. There is no one-size-fits all solution. Odemetry (wheel encoders) provide a cost-effective method to measure relative position. however suffer from wheel slip and errors are accumlate over time. GPS only works outdoors, effected by trees/buildings, and without a nearby basestation (for expensive DGPS/RTK) the absolute position error is several meters. IMU (accelerometers + gyros + Magnetometer) suffer from drift errors and noise error causing ``random walk'' when integrated. Magnetometer are effected by magnets, are slow to respond and measure magnetic north (not true north). Infrared are cost-effective, but short range and saturated by sunlight. Ultrasonic range sensors are cost-effective and good for detecting large objects, but can't detect glass/water, only measure a few metres, have a wide beam and provide medium accuracy. RADAR uses radio (instead of sound) to detect objects at long distance, but are relative more expensive then ultrasonic range sensors. Image sensors (video cameras) are a cost-effective, rich in information, and two or more can get depth information, but are computationally expensive, hard to process the data (aka computer vision), affected by dust/fog/rain, and light variations. LIDAR are high accuracy (about 1mm), however are expensive (prices are coming down every year), but can't detect glass/water. Distance measurement sensors are easy to interpret, other sensors are hard. Colour constancy and object classification is very hard (e.g. “Is it a tree or a human?”).
We have a deep understanding of control systems. We typically use Linux-based SBC's and a program a custom PID controller - perhaps even a cascade PID controller, bayesian filters, particle filters, kalman filters, Monte Carlo methods, or train a deep neutral network. The outputs of these systems might control various types of motors (e.g. brushed, brushless, servo, steppers) and/or various types of actuators (e.g. linear, pneumatic, hydraulic), and/or other things like lights or speakers.
We have been involved with computer vision and machine vision since early 2000's - we where involved in the development of two computer vision libraries before OpenCV became popular. Have done much biologically inspired techniques such as optical flow. Was involved in the early days of artificial intelligence using techniques such as Local Binary Patterns (LBP) and Haar-like features (HAAR). These days we typically use machine learning methods such as designing and training deep neural networks (outstanding for vision-based object recognition using ImageNet).
We where involved in the development of a robotic operating system which had 364,578 lines of code, before ROS was written.
We have developed custom software for various manipulators, and have a good understanding of forward and inverse kinematics.
We appreciate that challenges with robotics - particularly with robot navigation, computer/machine vision, and manipulation with the real-world, in real-time using real-robots.
We are confident with a broad range of skills and confident our Perth Robotics Development services can offer solutions such as:
These technologies can be used for various applications such as:
The CTO of COLETEK (Luke Cole) originally worked for Hemisphere GPS as a "Robotics Engineer" implementing auto-guidance solutions for agriculture tractors and quadbikes.
Lance Cole has also worked at NICTA and has a background of various hardware development, such as working for a contract company to the US millary (EOS), building the Common Remotely Operated Weapon Station (CROWS).
Perth is a town in the north-east of Tasmania, Australia. It lies 20 km south of Launceston, on the Midland Highway. The town has a population of 1,984 and is averaging a 1% increase per year (2001 census). Perth is part of the Northern Midlands Council. Federal Lyons MHR Dick Adams also has an office in the town.
It is the first major town out of Launceston on the route to Hobart, and also serves as a major junction for people bypassing Launceston on the route from Hobart to the north west of the state.
Like nearby Longford, Perth is a historic town with many buildings dating back to the early 1800s.
Perth is the capital and largest city of Western Australia. With a population of 1,650,000 (2009), Perth ranks fourth amongst the nation's cities, with a growth rate consistently above the national average.
Perth was founded on 12 June 1829 by Captain James Stirling as the political centre of the free settler Swan River Colony. It has continued to serve as the seat of Government for Western Australia to the present day. Its port, Fremantle is a city in its own right and slightly older than Perth.
The metropolitan area is located in the south west of the continent between the Indian Ocean and a low coastal escarpment known as the Darling Range. The central business district and suburbs of Perth are situated on the Swan River. Perth is ranked 4th on The Economist's 2008 list of the World's Most Livable Cities.
Perth became known worldwide as the "City of Lights" as city residents lit their houselights and streetlights as American astronaut John Glenn passed overhead while orbiting the earth on Friendship 7 in 1962. The city repeated its feat as Glenn passed overhead on the Space Shuttle in 1998
