Neurorobotics

For behavioral experiments, we use koala and khepera robots from k-team and various sensors. In the past, we tested robot chemotaxis (Martinez et al., 2006) and robot infotaxis (Martin-Moraud and Martinez, 2010) with gas and heat sensors, respectively. Currently, we use the antennae of tethered moths mounted on a khepera robot as pheromone sensors (Martinez et al., 2013; Martinez et al., 2014). See the figure below and the video section for more details.

 

Figure 1. Biohybrid robotics. The robotic platform is composed of a tethered moth A. ipsilon mounted on a Khepera III robot. The electroantennogram (EAG) acquisition board consisted of several stages: voltage regulation providing  ±5V from a +12V battery, differential EAG input, instrumentation pre-amplification (INA121), filtering and amplification (0.1-500 Hz frequency band, 50 Hz notch filter, ), signal conditioning (0-5 V) and analog-to-digital conversion (8 bits, 1 kHz sampling frequency). The EAG signal is transmitted wireless via WIFI to a remote computer and used as input to a neuron model. The neuron simulation is performed in real-time with SIRENE, a C-based neural simulator developed in our team. A surge command is transmitted to the cyborg after each pheromone detection.
