After a first contractor was incompetently slow and then sadly suffered a stroke literally days before it was hoped this project would finally be functional (he is still out indefinitely with a substantial sum of my money that may be forever gone now), and after a second contractor has now totally flopped with some more of my money while delivering nothing useful in time for an annual trade show (now over), I am now in a position where the patent protection period is half over for this system with nothing to show for it yet and essentially back to square one for finding a suitable contractor(s) to help. Time is now of the essence and becoming more critical with each passing day. This is a golf-related project that the industry needs very badly at this point in order to prevent the clubfitting trade from continuing its horrible and embarrassing performance record and reputation. Some knowledge of and/or interest in golf and the game's future might be a plus, but is not required and m...

We we need a robotics contractor, to help us succeed in our project. If have a strong background in computer vision, robotic sensor fusion and in control, please respond. This is a hourly job because I'm not yet sure what is possible, so would like to start with a feasibility analysis and go from there. The general milestones I expect are: 1. Discuss possibilities. 2. Agree to milestones. 3. A feasibility analysis and unit cost assessment of each. 4. Circuit design for one or more of these. We need a roboticist who is passionate about coding and lives to solve technical challenges. You should be obsessed with keeping your code neatly documented, excited by improvements in performance/efficiency/reliability, comfortable with ambiguity, and driven to make things work. You'll be working with custom-built controller boards, so knowing your way around a circuit is a must and past experience in robotic control is a huge plus. While decades of work experience is not necessary, you should ...

**Profile** We're looking for a developer with extensive experience in firmware design & development of Bluetooth Low Energy devices. We want someone who will take charge and doesn't need to be followed up to or managed. You will proactively suggest better ways of doing things when you discover them. You will raise red flags as soon as you see them. OSX application development experience or willingness to build a small test application (More about it below) is a big plus. **Work** The work is split into 3 parts. 1. Bluetooth Profile Design. You will carefully design the profile along with the structure of BLE services and characteristics for the device. 2. Firmware. There are again two parts to this. The most critical part of this is building a library to read/write the characteristics defined in the first part. The other is integrating the sensor libraries into the firmware so as to send the sensor data using the library written. 3. Test application. Write an OSX application t...

We need someone with experience programming the Nordic NRF51-822 chip. We have a linescan imaging sensor that we need to detect edges of an object and depth information based on illumination. The linescan camera will also have to be moved using an attached motor to capture a complete image. The linescan camera outputs 128 bits of illumination values and those will need to be parsed and data stored. Complete image with location of edges and depth will then be sent via BLE to a computer/iphone. Programming needs to be completely commented and succinctly written. We will perform the testing of the system. Work will need to be completed (including tested and verified by us) by March 16.

We are looking for a Mathematician/Robotic Engineer/Developer with strong background in math/quaternions/IMUs to help us improve a gimbal remote control application. We currently use an off-the-shelf 9DoF + fusion IC, and we are not quite satisfied with the results, so we are considering developing our own solution (possibly around the mpu6050/9150 sensors). There are also various calibration challenges that we're facing, mostly consisting of mapping rotations between different coordinate systems, which we'd like to also improve. That's where you come in. You'll help us finalize our proof-of-concept prototype by providing models/solutions for these problems. For prototyping we use Unity+C#+recorded imu tracers, but matlab/ other tools are also fine. Programming background is not required, as our developers will implement/adapt the solution(s) to the platform that will be used in the final product, but is always a plus. Requirements - Strong background in IMUs and sensor fusion - St...

We're an automotive start-up looking for very smart, creative individuals with hands-on experience of sensor fusion to help us extend and improve our mathematical driving models. Specifically we're looking for people with strong maths and statistics and a background perhaps in robotics or drones who have experience with location and orientation fusion techniques, including: > IMU fusion, calibration routines and techniques. > Implementing Kalman filters possibly EKF, UKF or particle filters. > In particular we're looking to handle both sensors with gaussian (e.g. MEMS sensors) and non-gaussian noise (e.g. GPS sensors). It's anticipated the models will be written/validated in Matlab/Octave and and later implemented in Java/C++. We're primarily looking for the former skill-set, though the latter will be a bonus. Kindly reply with relevant background information and I'll send over more information on the project. Cheers, Mark

My main goal at this time is to add an avatar (character to our now skeleton or stick figure, so if someone can use our software do that by using windows 10, we would not need to use Unity. Either method is fine with us. By the way we used a kinect2 as the sensor in this project.

This project is to develop a sensor network system. The network will consist of many identical but configurable sensors wired together in a daisy-chain. The sensor PCB is already designed but needs to be debugged. Therefore most of the work will be in writing and debugging the firmware. Each sensor module will have a button for configuring the function of the sensor. For example one sensor might be configured to trigger an alarm when a switch closes. There will be approximately 17 commands related to sensor configuration and control. We are not using a standard network protocol. Firmware must be in C for an 8 pin PIC PIC12F1822-I/P-ND. The sensor network cable will have a total length of up to 500 ft so the firmware must consider noise immunity. Confidential details will be provided to qualified applicants after which you can fine-tune your bid.
