PROJECTS

Current Projects

Some of our projects are proprietary. Here are a few of the things we’re working on now.

TIK-TOK

Tik-Tok is an open-source humanoid robot developed to an early prototype stage at Cornell University, with help from a National Science Foundation grant. It weighs 30 kg and stands 1.5 m tall. Its design is intended to give dynamic performance rivaling the robots from Boston Dynamics, while enabling highly energy-efficient walking and running. Simulation results suggest that the robot should be able to walk at a normal human pace for 10 km on a single charge of a 2 kg lithium-polymer battery. In addition to legged robots, Tik-Tok’s technology could be of value in a range of fields, from UAVs to exoskeletons and prosthetic devices.

Dynaloco has licensed the technology from Cornell for further development but the original open-source design files continue to be available here. Contact sales@dynaloco.com for more information on our technology or robotics internship opportunities.

prototype high-power linear actuator

Optimized selection of motor, transmission, and driver, along with FEA-refined hardware design, gives these actuators industry-leading power- and force-to-weight ratios. The actuator shown has a peak force of 4400 N, a peak speed of 0.5 m/s, and an estimated peak power of 1100 W, with a weight of 1.1 kg. A similar but larger actuator design gives a peak force of 4900 N, a peak speed of 1 m/s, and an estimated peak power of 2450 W, with a weight of 1.9 kg.

open-source motor driver project

Developed along with our biped robot, these motor driver boards and related electronic hardware are designed for extreme peak power capability, while keeping quiescent power consumption to a minimum. As shown here, the motor driver has a peak power output of 100 amps RMS, with a DC input voltage of up to 70 volts. The allowable average current will vary with the heat sink design, from about 30 amps (air-cooled, minimal heat sink) to 100 amps (water-cooled). This design stands out from the competition for its very low quiescent power, at less than 500 mW when driving zero current to the motor. This makes it suitable for a wide range of battery-powered robot applications, particularly those with dozens of motors running at typically low power levels. The rest of the CAN-FD bus-based support boards (force and angle sensors, etc.) are also designed for very low battery drain.

Early SailVane proof of concept, developed by a team of students at Cornell University

sailvane

With this long-range, low-cost drone sailboat we aim to do for ocean monitoring what aerial drones have done for terrestrial surveys. The innovative rudder/sail design allows for a system powered only by wind, currents, and a small rechargeable battery, meaning that SailVane can remain at sea for many months at a time.We are presently pursuing funding for continued development and commercialization of our sailboat micro USV project. To discuss this or custom hardware development to meet your specific ocean research and data collection needs, contact us at sales@dynaloco.com.

Past Projects

mINI AIRCRAFT CARRIER

The world’s smallest aircraft carrier? Developed along with other Aerovel Corporation personnel, this mini aircraft carrier can autonomously launch, land, refuel, restart, and relaunch the company’s VTOL long-range UAV. See the full demonstration video here.

Contact sales@dynaloco.com to discuss ways we can help you with your machine design project.

ranger

Cornell University’s Ranger robot was developed by a team of students working with company co-founders Andy Ruina (principal investigator) and Jason Cortell (lab manager and lead engineer). Unlike other walking robots that use position control of every angle of every limb, Ranger emulates human walking; the motors work with gravity and leg dynamics to swing the legs. For a time Ranger held the world record for nonstop robot walking distance, at 65 kilometers on one battery charge. The goal of the research was not only to advance robotics but also to learn more about the mechanics of walking. Besides building better robots, applications include rehabilitation and prosthetics for humans, and even improved athletic performance. See more Ranger videos here.

HOPPER

Developed with the Robotics Laboratory at UCSB, the FRANK hopper robot is a fully 3D cable-driven electric monopod. When equipped with the right sensors and controls it can leave its boom behind and take to the streets, with hours of operation on a single battery charge.

Contact sales@dynaloco.com if you would like us to build a new and improved version of FRANK for your lab or other application.
